Description

 Further, for short, this furnace is called "Ruenka" (manual, universal, economical, full-scale, comfortable, accumulating ash).

The Rouenca furnace can be used:
- on a personal plot of land outside the building (cottage, garden, garden, yard, farm, forest, etc.), as well as in a home fireplace, in a bathhouse, in a greenhouse;
- on a picnic, on a hike (in the forest or in the steppe, in the mountains or in the valleys, on hunting or fishing, sailing on a raft on a river or lake, etc.).

 Known marching furnace - an analogue closest to the invention in terms of essential features (USSR patent 1779284 A 3, F 24 C 1/16, 11/30/92), containing a housing with openings for the exit of flue gases in the upper part of the side surface and an opening for installation heat receiver (tank with a lid-frying pan) and a furnace, characterized in that in order to increase efficiency and reduce dimensions in the transport position, the casing is made of an upper movable (with non-standard tank) height part with a position lock relative to the fixed lower part, and the upper edge of the latter is made in the form of a damper overlapping the cross section of the gas outlet openings.

This famous camping stove:
- provides the possibility of stepwise lowering the dishes with food to burning wood as they settle in connection with burnout, which gives increased efficiency in obtaining thermal radiation from dishes with food;
- provides the ability to fix the dishes with food at a height corresponding to the power of the combustion chamber needed to prepare a specific hot dish, which gives less loss of thermal radiation, in particular, when the remaining firewood is burned in the combustion chamber of the furnace after the completion of the next cooking in it, and therefore , and increased efficiency for the release of thermal radiation in the combustion chamber.

Known to the applicant the reasons that impede the receipt of the required technical result by an analogue closest to the invention:
(1) air intake occurs only from the bottom side of the parallelepiped volume of firewood in the combustion chamber. Therefore, in the middle and especially in the upper part of the combustion chamber and the firebox, there is the so-called chemical underburning of the combustible fractions of smoke (i.e., combustible gases and volatile combustible soot emitted during combustion) due to a lack of oxygen, and therefore a reduced efficiency in heat radiation in the combustion chamber from burning wood (see Fireplaces and stoves. - M .: Adelant, 2000, p. 31). In addition, there is burning of firewood in the combustion chamber at the same time only on one side of the volume of firewood in the chamber, namely only on the lower side, and consequently, the reduced power of the furnace;
(2) the ash remains in the combustion chamber for the entire time the furnace burns, prevents oxygen from reaching the lower layer of firewood in the combustion chamber, as a result of which they are incompletely burned, i.e., the so-called mechanical underburning, which reduces the efficiency of heat emission in the chamber burning (see Fireplaces and stoves, p. 30);
(3) the absence in the analogue closest to the invention of a separate kindling chamber that kindling firewood in an oven makes an uncomfortable (painful) operation;
(4) the absence of burners for the use of any (including standard and with any size) dishes or skewers (except for non-standard pots and lid-pans) for cooking hot food, including several floors, and with the possibility of moving dishes or skewers with any floor to any upper or lower floor. Therefore, having boiled porridge, for example, in a marked tank, it is impossible to boil more water for coffee in a standard pan - first you need to eat (or unload from the tank) porridge, scrape and wash the tank and only then can you boil coffee water in it;
(5) the absence of openings for laying fuel in the furnace in addition to the existing upper and front doorways, which reduces the comfort of loading the furnace with fuel. For example, in the case when the wind blows into the rear side of the furnace, putting additional firewood into the combustion chamber with burning wood in it from the back side is much more convenient than loading from the front side.

The absence of opposing openings, and therefore the absence of additional straight horizontal traction due to the use of wind, slows down the drying of firewood in the combustion chamber in the period from laying firewood into the combustion chamber immediately after the end of the previous preparation of hot food to the beginning of the subsequent preparation of hot food, reduces the efficiency of heat release radiation in the combustion chamber from burning wood in it, slows down the kindling of firewood;
(6) lowering the upper height-movable half of the furnace body with a non-standard food tank into the combustion chamber of the furnace to bring the food tank to the burning wood as it settles due to burning out is a relatively complicated operation;
(7) lowering the upper half-movable furnace body with a non-standard food tank into the combustion chamber of the furnace to obtain the desired reduced volume of the combustion chamber is a relatively complicated operation;
(8) the number of available power sizes in kilowatts of the combustion chamber is not enough, since hot dishes differ by a greater number of times in terms of the thermal radiation power required for their preparation;
(9) the insufficiency of the area of the internal horizontal cross section of the chimney (by the chimney means the space between the furnace body and the tank with food) in its smallest part relative to the area of the internal horizontal section of the combustion chamber, i.e. the insufficiency of the ratio (fraction) of the first area of ) of the second area, and consequently, the lack of performance of the chimney (also called smoke exhaust, smoke consumption or draft) in cubic centimeters of smoke per minute.

In this regard, in the middle, and especially in the upper part of the combustion chamber and the firebox, there is a chemical underburning of the volatile combustible fractions of smoke (i.e., the combustible fractions of gases and volatile combustible soot released during the combustion of firewood) due to a lack of oxygen, and therefore reduced efficiency for the release of thermal radiation in the combustion chamber from burning wood in it. In addition, there is a reduced intensity of burning wood in the combustion chamber, and therefore a reduced power of the combustion chamber, especially at the stage of drying and burning wood, when an increased amount of smoke is generated due to the slow burning (decay) of the wood and increased formation of water vapor;
(10) it requires labor to clean the outer surfaces of the vertical front, back, left, right walls of the firebox from accidentally escaping liquid from the dishes (soup, porridge, mushrooms, milk, jelly, etc.) in connection with its explosive boiling;
(11) when using the furnace outdoors on a personal plot of land after two or three sources of the furnace, labor is required to remove wood ash from the furnace, pour the ash into a bucket and carry the bucket to the accumulation site as a valuable and scarce potassium-calcium-phosphorus stock magnesium fertilizer, as well as a reserve of means for controlling pests and diseases of garden plants.

In addition, the camp stove has structural elements that are not necessary when the stove is working outdoors, that is, in nature, in nature (these elements are marked with the letter "n"):
1h) non-opening of the rear wall of the firebox,
2h) insufficient size of the doorway of the firebox due to the presence of two door hinges and one lock for a tight (smoke) fit of the edges of the door to the front wall of the furnace body and due to the presence of a high threshold in the firebox housing for delaying ash,
3h) the low location of the furnace from the floor level to ensure heating of the lower layers of air in the room,
4h) continuity (for anti-smoke) of the firebox housing, which unnecessarily makes the furnace heavier.

 A tourist convertible stove is known - an analogue less close to the invention in terms of essential features (RF patent 2085812 C1, F 24 C 1/00, 07.27.97), comprising a housing, a non-standard cooking container, a combustion chamber made of two knees, located in the space between the housing and the tank with the possibility of extending them down vertically, the lower of which is equipped with a door and a perforated bottom, as well as a chimney in the form of a separate pipe of rectangular cross section and rotary supports, characterized in that the tank is made it can be extended up and down vertically and has dimensions equal to the internal dimensions of the lower knee, the chimney has a length and width equal to the corresponding internal dimensions of the container, with the possibility of sequentially inserting the chimney into the container and containers with the chimney into the lower knee through the door opening, and the combustion chamber is equipped with a deflector located on the upper flange of the upper knee.

 This well-known tourist convertible stove has the same features that coincide with the essential features of the claimed invention as the camp stove described above, as well as such reasons known to the applicant that impede the desired technical result of a tourist convertible stove as the above-mentioned camp stove (for with the exception of the reason (9), as well as the fact that in the above-mentioned reasons (6) and (7) in the tourist convertible furnace there is no lowering of the upper half of the body moving with height furnaces with a non-standard food tank in the combustion chamber of the furnace, and lowering only a non-standard food tank in the combustion chamber of the furnace).

In addition, the tourist convertible stove has structural elements that are not needed when the stove is used outdoors: 1n), 2n), 3n), 4n), as well as:
5h) a chimney, which with a length of less than 0.7 m / 1 kW of furnace power is unnecessary (decorative), and with a longer pipe, the furnace, due to its cumbersomeness, turns from manual to non-manual,
6h) restriction by the lower arrangement of windows for air intake into the combustion chamber of the furnace.

 A known oven-analogue tourist stove (RF patent N 2000519 C, F 24 C 1/00, 09/07/93) is even less close to the invention in terms of the essential features, which has only one feature that matches the essential feature of the claimed invention, namely the possibility of fixing dishes with food at a height corresponding to the power of the combustion chamber needed to prepare a specific hot dish, but does not have a second feature that matches the essential feature of the claimed invention, namely it does not have the possibility of stepwise lowering utensils with food for burning wood as they sink in connection with burnout.

- has two doors, that is, four door hinges and two locks, which unnecessarily complicates the furnace.

 Known small furnace for field installation (application Germany N DE 3128298 F1, F 24 C 1/16, 04/14/83), comprising a housing, a burner on the top panel, a combustion chamber and a grate, characterized, firstly, in that it consists of a thin tin casing, which can be packed in one flat bag for transportation after disassembling, and when the furnace is installed, the tin plate is bent into a round or oval casing around a round grate, secondly, a small tin cylinder is put on the grate inside the tin casing the combustion chamber, thirdly, by the fact that between the lower cr At the foot of the casing, an air gap is left with a width of at least 10 mm, fourthly, because a horizontal ring is placed on the edge of the casing on the top panel formed under the pan around the pan.

 A small furnace for a field installation does not have two of the above essential features of the claimed invention; of the above reasons that impede the achievement of the required technical result, it has the reasons: (1), (3), (8), (9), (10); the "small furnace for field installation" has structural elements that are not needed when operating the furnace outdoors: 1n), 3n), 4n), 6n).

 Known cooking stove (RF patent N 2067729 C1, F 24 C 1/00, 10.10.96), comprising a housing formed by mounted on top of each other with a bottom and a lid, a heating device and an exhaust pipe, characterized, firstly, in that that the containers are made stepwise expanding upward and placed in a casing over which an exhaust hood is placed, each container being covered by a heat-insulating lid, and secondly, by the fact that it is equipped with a flame tube placed in the center of the stepwise expanding upward axis, along the axis of which there is a rod with n and pipes with flanges, each step of the flame tube is blocked by a shutter resting on the steps of the flame tube and collars of the tubes, the upper step is covered by a lid, and washers in contact with the lid are placed at the ends of the tubes, and thirdly, that it is equipped with a between the casing and the outer surface of the upper tank and attached to the last fixed ring with exhaust holes and mounted on it a movable ring with holes and a pin, fourthly, the fact that it is equipped with a cylindrical ring ayuschim casing, fixed and movable ring and an umbrella.

The cooking stove does not have the two above essential features of the claimed invention; of the above reasons that impede the achievement of the required technical result, it has reasons: (1), (3), (5), (8), (9), (10), (11); the cooking stove has structural elements that are not necessary when operating the furnace outdoors (the heating is described above in the field conditions): 1n), 2n), 3n), 4n), 5n), 6n), and, in addition:
- it is doubtful that the purpose of the stove is because of its bulkiness, since the stove is essentially three wood-burning samovars, set one on top of the other, and this general three-story building is also equipped with a common heat-insulating casing,
- has an umbrella with a shutter that is not necessary when the furnace is working outdoors and therefore unnecessarily weighting the furnace; the operator (cook) cannot see the food during its preparation, which can reduce its quality and lead to an excessive consumption of fuel (it is indicated in the description of the invention that a thermometer sensor is installed inside the case to control the degree of food heating).

 Known heating and cooking stove (RF patent 2097657 C1, F 24 V 1/26, 11.27.97), comprising a housing with a protective casing, a lid, a grate, an ash chamber, a fire chamber, between the walls of which a heat-resistant lining, blowing a chamber with an ash box, characterized, firstly, by the fact that the casing is equipped with a gas circulation, the grate is made of thin-walled V-shaped cross-section of the bundles, filled with heat-insulating material, the blower chamber is made with internal protective walls, the spring is provided on the outside air shutter, and, secondly, the fact that the body is equipped with fins.

The heating and cooking stove does not have the two above essential features of the claimed invention; of the above reasons that impede the achievement of the required technical result, it has the reasons: (1), (3), (5), (10), (11); the "heating and cooking stove" has structural elements that are not necessary when the stove is working outdoors (the invention described above that it can be used, in particular, in household plots): 1n), 2n), 3n), 4n) 5n), 6n), and in addition:
- has a gas circulation and protective walls of the ash chamber, not needed when cooking food outdoors and therefore unnecessarily weighting the furnace,
- has a reduced temperature of the hob due to lowering the temperature of the exhaust gases by gas circulation.

 The objective of the invention is to eliminate the above reasons that impede the receipt of the required technical result by the above-described analogue closest to the invention.

 The household solid-fuel handheld household marching food-cooking-heating-entertaining "Rouenka" consists of a removable over-column firebox, which is placed on top and is put on a little on a removable ash-collector column.

 The combustion chamber of the firebox is made in the form of a lattice basket of sparsely spaced rods placed in an air jacket between this basket, on the one hand, as well as four continuous sheet vertical walls of the firebox and a removable continuous sheet hearth of the combustion chamber mounted on the frame of the firebox, close - but not close - located on a fixed fixed trellis hearth, on the other hand.

 The air jacket is freely in communication with the outside atmosphere through 19 ribs of slit-like windows with a thickness of the order of 10 mm and a total length of 4600 mm for sucking air along the entire length of each of the edges of the frame of the firebox and is the place of afterburning of the combustible fractions of smoke, with the removable removable solid sheet hearth removed below the fixed fixed the lattice hearth of the combustion chamber is the upper half of the firebox ignition chamber.

 The furnace firebox has sliding-sliding burners located one below the other in several floors.

 One pair of one front and one rear removable rod of the upper floor of the grate basket of the combustion chamber, lying on top of the frame of the firebox, is a sliding-sliding pair, which, when the rods are moved towards each other, forms a ring for any cookware without restrictions, and when sliding, for any skewers.

 Below the first burner on top and above the last burner on top, each pair of one front and one rear fixed bar with bent ends of the same floor of the grating basket of the combustion chamber lying on the left and one-story right side of the fixed fixed fixed rods of the grating basket is movably - a sliding pair, which, when the rods are moved towards each other, forms a burner for any dishes within the lattice basket or for removable solid sheet under or under the firewood, and when extended, about Orae under any skewers.

 The lower fixed fixed rods of the trellis basket of the firebox of the firebox form a burner in the form of a fixed motionless trellis hearth, that is, the grate of the combustion chamber of the firebox, under any utensils within the trellis basket or under removable solid sheet under or under firewood.

 Each of the front and rear walls of the firebox has one internal hinged hook, and the removable continuous sheet under the combustion chamber of the firebox has a threshold that delays ash.

Sliding-sliding burners located on five floors and one fixed hearth (i.e. the first from the bottom) the burner (listed below from top to bottom) have the following name, design, height from a fixed fixed trellised hearth (that is, first from the bottom), the name and size formed by a constant-burner burner power of the combustion chamber for any cookware whose outer diameter is less than the length and width of the internal horizontal square section 200 x 200 mm of the combustion chamber and which therefore can be lowered Whether slide in front firebox (under combustion postoyannopodovoy power is meant power combustor chamber formed between the stationary, i.e. constant, trellis hearth combustor and used in the particular case of one of the five burners upstream):
- top burner. It consists of two removable sliding-sliding rods with a handle and an end bent at 91 ^o (each of these two rods also serves as a poker). It is located from a fixed trellised hearth ring (i.e. from a trellised hearth of a combustion chamber) at a height of 270 mm. It forms a combustion chamber with a power called hearth-top power in the amount of 2.0 kW (this name comes from the names of the marked two burners - "upper" and "hearth", which form the indicated power);
- upper, middle, sub-middle, supra-buccal (i.e. four) burners. Each of them consists of two non-removable sliding-sliding rods located from the stationary lattice hearth of the combustion chamber at a height of 216, 162, 108, 54 mm, respectively. It forms a combustion chamber with a hearth-power rating of 1.6 kW, with a hearth-super-average power of 1.2 kW, with a heart-and-medium power of 0.8 kW, and a hearth and power of 0.4 kW;
- hearth burner (it also serves as a fixed fixed trellis hearth, as well as the grate of the combustion chamber and, in addition, the lower side of the trellis basket of the combustion chamber of the firebox). It consists of fixed fixed seldom located (at a distance of 30-40 mm from each other) rods, spaced from the removable sheet hearth located below them only at a height of 18 mm. It forms a combustion chamber for fuel chips, small flames and coals with a hearth power of 0.1 kW.

 The middle (i.e., the fourth bottom) burner, in addition to two fixed movable rods, has two fixed fixed (front and rear) rods for hanging on them a removable front flap and a removable rear wall, respectively.

 Of the six burners, four (upper, middle, middle, supernatal) in the extended (that is, in the “shirt”) position also serve as skew-holders for simultaneously placing 12 skewers with food (three skewers on each burner).

 Compared to the variable-power output described below, constant-power power has an increased efficiency in obtaining thermal radiation from dishes or skewers with food or wood for their drying due, firstly, to the possibility of simultaneously multi-storey setting up several dishes or skewers with food or firewood (for their drying, starting from a height of 70-100 mm from dying coals) and receiving thermal radiation of smoke, and, secondly, receiving utensils or skewers with food or wood to dry thermal radiation from the combustion chamber, reflected about the vertical removable front flap of the firebox, its removable rear wall and its left and right side walls.

Five sliding floors located on five floors, one fixed hearth ring and a removable continuous sheet for the firebox also form the following five dimensions of variable-power combustion chamber for any cookware whose outer diameter is greater than the length and width of the internal horizontal square section 200 x 200 mm of the combustion chamber, and therefore, it is impossible to lower such dishes from above or push them in front into the firebox, but can only be used on the top burner (under the variable-output power of the combustion chamber there is in view of the power of the combustion chamber formed between the upper burner and used in a particular case of one of the five lower burners):
- bottom-top power of 2.0 kW. It is formed by sliding a removable continuous sheet hearth under a fixed fixed lattice under the combustion chamber and laying firewood from the fixed fixed lattice hearth (that is, from the hearth ring) to the upper burner, i.e. to a height of 270 mm. The hearth-upper power was mentioned earlier in the description of the upper burner;
- Supra-underhead power of 1.6 kW. It is formed by sliding a removable continuous sheet hearth onto a hearth ring and laying firewood from the supra-sub ring to the upper ring into the combustion chamber, that is, to a height of 216 mm;
- sub-upper power 1.2 kW. It is formed by sliding a removable continuous sheet hearth onto a supra-pod burner and inserting firewood from the middle burner to the top burner into the combustion chamber, that is, to a height of 162 mm;
- super-upper power 0.8 kW. It is formed when the removable continuous sheet hearth is moved onto the middle burner and the firewood is placed in the combustion chamber from the middle burner to the upper burner, that is, to a height of 108 mm;
- super-upper power 0.4 kW. It is formed when the removable continuous sheet hearth is moved onto the middle burner and the firewood is placed in the combustion chamber from the upper burner to the upper burner, i.e. to a height of 54 mm.

 The removable overhead column firebox of the Rouenca furnace is used not only in conjunction with a removable ash collector, but also as a separate independent furnace, for example, on a picnic, on a hike (in the forest or in the steppe, in the mountains or in the valleys, on hunting or fishing swimming in a raft on a river or lake), where the collection of wood ash is not relevant, as well as in a home wood fireplace, in a bath with an exhaust hood (or without it when heating "black"), where heating is required and the lower layer of air .

 When used as a separate independent furnace, the removable overhead column firebox of the Rouenca furnace is a manual furnace, that is, it can be carried manually due to the relatively small weight (weight) of the furnace without removable parts in the amount of 8.8 kg and the volume of the furnace with dimensions of 360 x 410 x 420 mm with a relatively large maximum furnace power of 2.0 kW.

The removable ash collector is a parallelepiped-shaped tank with a front (front) length of 260 mm, a side length of 350 mm and a height of 490 mm, without an upper wall, with a drainage hole on the lower wall (bottom) for a delayed (creeping) discharge, accidentally “escaping” from liquid dishes in connection with its explosive boiling, but without entrainment, together with the liquid, of ash from the ash column, and when using the furnace outdoors on a personal plot of land, it simultaneously performs the following functions:
- ashpit function,
- the function of the container for semi-automatic non-portable accumulation of wood ash in a volume of up to 36 l,
- the function of the stand (pedestal) for the removable overhead column firebox of the furnace to ensure a comfortable (for an adult of average height) arrangement of the control parts of the furnace and its most often serviced nodes (removable front damper handles, removable rear wall handles, burners, combustion chambers, removable solid sheet hearth, utensils and / or skewers with food in the firebox, firebox chambers, etc.) at a height of 600-800 mm from the ground level, at which an adult of average height does not need to bend down, squat, kneel, etc. d. when servicing the furnace.

 The ash is discharged from the combustion chamber of the removable over-column firebox of the furnace to the ash column of the furnace (including during the combustion of fuel in the grating basket of the combustion chamber) either by juggling the removable sheet hearth of the combustion chamber, which consists in almost fully ejecting it and then fully sliding it back removable sheet hearth (which resembles jerking the rifle shutter, but without its rotation), or by fully extending the removable sheet hearth, its light impact on the front fixed rod above the middle (i.e. fourth from the bottom) burners (so that ash is poured from a removable sheet hearth into the ash column) and moved to its original place. In this case, the ash will instantly fall into the ash column of the furnace.

 On a private land plot outdoors, the Rouenka stove is conveniently used in a kit consisting of one removable over-column firebox and two ash collectors.

 So, at the summer cottage, the Rouenka stove is more convenient to use in a set of two ash collectors (placed on opposite sides of a summer (that is, extra-ordinary) dining table) and one removable over-column firebox, which, depending on what, needs smoke to the table ( for example, to drive away mosquitoes) or not needed (for example, in winter), is placed on one or the second ash collector column. When changing the direction of the wind during lunch, one person can easily transfer a removable over-column firebox (including firewood burning in it) from one ash collector to the second.

 In addition, the second ash storage column is convenient and as a significant one (reserve) capacity for the accumulation of wood ash, because the ash is produced all year round (the Rouenka furnace can be heated outside the house all year round, and in addition to this in the winter in the country house Usually, they also heat a home stove with firewood), and wood ash can be used as a fertilizer and / or a means of controlling pests and diseases of garden plants only in the absence of snow cover.

 When using the Rouenka furnace in a greenhouse or outdoors in an open (unprotected from cold) summer cottage as a smoke and water vapor generator during spring frosts to save heat in the soil and in the adjacent layer of atmospheric air after igniting not quite dry firewood, branches, grass, etc., in order to obtain a longer (an order of magnitude) burning time, they need to cover the removable overhead column firebox on top with a baking sheet, which will reduce the smoke draft by an order of magnitude, and therefore, increase the duration by an order of magnitude burning one bookmark wood, twigs, grass and the like. g. in the combustion chamber.

The spectacular use of the Rouenka stove (that is, the use of the stove with the removable front damper removed as a civilized fire) compared with a conventional fire with the same amount of firewood burned has the following advantages:
- gives a higher flame (due to greater efficiency in the release of thermal radiation in the combustion chamber due to the reflection of the rear, left, right leaf vertical walls of the firebox back into the combustion chamber of thermal radiation from the fuel burning in it and due to the greater burning power of firewood for their burning, not only from above, front, back, left, right, but also from below), and, consequently, better illumination of the front hemisphere of the surrounding landscape,
- the soil under the furnace is not destroyed (does not burn out), the soil under the furnace is not dirty with ash and soot, and the wood ash is not clogged with soil and is not lost on the soil.

 FIG. 1 - the Rouenka furnace in a set of one removable over-column firebox 1 (containing a removable front damper 2, fixed left 3 and right 4 side walls), standing (slightly worn) on the ash column 5, standing on stones (cobblestones) 6, lying on the ground 7.

 FIG. 2 - Rouenka furnace with a removable front flap, a removable rear wall, a removable sheet hearth and eight front and rear rods 8 of four sliding-sliding burners of the combustion chamber located one below the other in the combustion chamber removed for better viewing by the firebox four floors.

 In FIG. 2 front and rear rods can freely move along the fixed left 9 and one-story right 10 side rods inserted into an opening in the shelf of the vertical corner 11 of the firebox frame.

 The left and right side walls are hung on the marked frame. In FIG. 2 the lattice basket of the combustion chamber (except for rods 8, 9, 10) on the top contains two removable sliding-sliding elongated (with a handle and with a bent end) rod 12 of the upper (i.e., sixth from the bottom) sliding-sliding burner, and from the bottom contains seven to eight fixed fixed rods 13 hearth (that is, the first bottom) burner (that is, rods fixed fixed trellis hearth or grate) of the combustion chamber.

 In addition, in FIG. 2 between the trellis basket of the combustion chamber of the firebox and the sheet walls (front, back, left, right, lower) of the firebox there is an air shirt 14.

 However, in FIG. 2 it is seen that below the rods 13 of the grate of the combustion chamber is a chamber for igniting the firebox with its grate of fixed rods 15.

 In FIG. 2, the Rouenka oven is prepared for cooking on one tab firewood of fried potatoes in a pan that does not fit inside the combustion chamber of the firebox and is therefore placed on the top (that is, the sixth bottom) burner. The combustion chamber is formed between the super-middle (i.e. the fourth from the bottom) burner and the upper (i.e., the sixth from the bottom) burner, has a height of 108 mm and a super-high power of 0.8 kW. In this case, the kindling chamber temporarily serves as the space between the sub-middle (i.e. third from below) burner of the combustion chamber and the above-average (i.e. fourth from below) burner of the combustion chamber (and not the nominal kindling chamber with its grate 15). In FIG. 2 shows the paper pushed into the marked temporary ignition chamber to ignite the firewood in the combustion chamber.

 As the firewood settles in connection with their burning out, a removable continuous sheet with firewood burning on it will step up to the higher burners to bring burning firewood closer to the bottom of the pan with roasting potatoes in order to increase the efficiency of obtaining thermal radiation from the pan with potatoes.

 The possibility of carrying out the invention is confirmed by the following.

 The Rouenka stove can be used outdoors, for example, in the forest part of a summer cottage in a set of one removable overhead column firebox 1, one ash column 5 standing on stones 6 lying on the ground 7 in the shade a few meters from the forest dining table to northeast (if the prevailing wind in the summer cottage is from the southwest), and the second ash column, standing in the sun a few meters from the forest dining table to the west (if the place is sunny).

 The first or second ash collector column is used depending on the following factors: firstly, from the need for the furnace to stay in the sun or in the shade (in the heat it is more convenient to heat the stove in the shade, and in the cold in the sun), and secondly, from the need for the movement of smoke from the stove to the forest table (to drive away mosquitoes) or from the table (in the absence of mosquitoes), thirdly, from the need for additional capacity for the accumulation of wood ash (in spring, summer, autumn, there is no such need, because the whole wood ash goes to fertilize and protect the garden GOVERNMENTAL plants from pests and diseases, and in the winter there is such a need, t. To. The whole wood ash is in storage).

 The removable over-column firebox of the Rouenka furnace contains (spark-reflecting and bearing all normal strength loads on the firebox) a parallelepiped-shaped frame from corner 11, mainly of type 25 x 25 x 4 mm.

 Inside the firebox frame at a distance of 14 mm from the inner wall of the corner of the frame, the firebox contains a trellis basket (rarely, at a distance of 18-36 mm, rods 8, 9, 10, 12, 13 located apart from each other) of the combustion chamber to form an air jacket 14 around of all (six) sides of the volume of firewood in the combustion chamber, including the rear, left, right vertical sides of the air jacket are 30-40 mm thick, the lower side of the air jacket is 18-54 mm thick.

 This air jacket on the outside for reflection back into the combustion chamber and on dishes and / or skewers with heat radiation from the wood burning in the combustion chamber has five separate continuous sheet walls: a removable front wall mounted on the firebox frame at a distance of about 10 mm from the outer wall of the corner of the frame a damper 2, hinged on the firebox frame at a distance of about 30 mm from the outer wall of the corner of the frame, a removable rear wall, hinged on the firebox frame at a distance of about 20 mm from the outer wall of the corner of the frame, fixed left 3 and right 4 side walls, a removable continuous sheet under the combustion chamber at a distance of 18-54 mm from the fixed lattice hearth of the combustion chamber.

 When the removable continuous sheet hearth of the combustion chamber is removed, the place below the fixed fixed trellis hearth of the combustion chamber is the upper half of the firebox ignition chamber with its grate from the fixed rods 15.

 The top of the air jacket does not have an upper horizontal sheet wall (panel), in particular because the reflection from top to back into the combustion chamber of thermal radiation from the wood burning in the combustion chamber is carried out by the bottom of the dishes and / or skewers with food.

 The combustion chamber is at the same time the place of smoke formation, including its combustible fractions, and the air jacket is also the place of burning of combustible smoke fractions (i.e., combustible gases and volatile combustible soot emitted during combustion).

The lattice basket of the combustion chamber contains:
- left and right: left 9 and right 10 lateral straight fixed fixed rods inserted into holes in the shelf of two vertical corners 11 of the left (and right) side of the firebox frame at a distance of 18 mm from the outer edge of the corner;
- front and rear: sliding along the left and right side direct fixed fixed rods fixed removable sliding-sliding rods 8, in particular, for the formation of four burners, located one below the other on four floors under any food grid or under a removable solid sheet under or under firewood, namely the upper burner (fifth from the bottom), the middle (fourth from the bottom), the middle (third from the bottom), the supra-gen burner (second from the bottom);
- above: two removable sliding-sliding elongated (with a handle and with a bent end) rod 12 for the formation of an additional burner for any unlimited food utensils, namely the upper (sixth from below) burner;
- bottom: seven to eight rarely located (at a distance of 30-40 mm from each other) fixed fixed rods 13 of the grating hearth of the combustion chamber for the formation, in particular, of another burner for any dishes with food within the grating basket and for removable solid plate under, namely the hearth (first from the bottom) of the burner.

 To use the Rouenka furnace on a personal plot of land (cottage, garden, garden, yard, farm, forestry, etc.), the furnace under a removable over-column firebox contains a removable ash collector made of steel 1 mm thick in the form of a parallelepiped-shaped tank with a front (front) length 260 mm, side length 350 mm, height 490 mm and capacity 36 l, without upper wall, with a drainage hole on the bottom wall (bottom) for delayed (creeping) discharge of fluid that accidentally “escaped” from the dishes due to explosive boiling it, but without entrainment place with liquid ash from the column-zolonakopitelya, weighing 5.0 kg to ensure vertical stability oven from tipping when a strong random grazing and / or pushing the furnace. The action (work) of the Rouenca furnace.

 The Rouenka furnace has the following customizable multifunctional tools: movable rods of the trellis basket of the combustion chamber, multi-floor sliding-sliding burners of the firebox, removable continuous sheet hoisting-lowering sliding-extendable under the combustion chamber.

 The setting for the action (operation) of these multifunctional means consists in determining a specific fuel-saving value (parameter) for each specific function of the marked customizable multifunctional means of the Rouenka oven, depending primarily on the desired menu of hot food dishes, and secondly on the number of available menus dishes for preparing hot dishes, in the third turn - from the menu of the type and size of the power of the combustion chamber of the Rouenka furnace, in the fourth turn - from the menu of the location of the combustion chamber and the combustion chamber ignition of the Rouenka furnace, in the fifth place - from the menu of the number and type of different-floor sliding-sliding burners for cooking hot dishes in the dishes at the same time on the different-level rings of the Rouenka furnace, in the sixth place - from the menu of the location of the removable continuous sheet lifting-lowering sliding - retractable hearth of the combustion chamber of the Ruenka furnace.

Several menus of types of utensils for cooking hot food include the following menus of types of utensils that affect the setting of the multifunctional means of the Rouenca oven:
- a menu of types of dishes in relation to standard: standard dishes, non-standard dishes (for example, non-standard dishes require non-standard settings for a sliding-sliding burner),
- a menu of types of cookware according to its diameter relative to the size of the horizontal section of the lattice basket of the combustion chamber (the type of cookware in this menu determines the type and size of the power of the combustion chamber of the furnace),
- a menu of types of cookware in relation to the possibility of lowering cookware to the lower burner: lowering is possible, partially lowering is possible, lowering is not possible (the type of cookware on this menu determines the location of the furnace combustion chamber),
- a menu of types of dishes according to the size of its side (the type of dishes on this menu determines the number and types of different-level burners for cooking hot food in dishes at the same time on different-level burners).

The custom multifunctional movable rods of the trellis basket of the combustion chamber have the following functions (these functions are indicated by the letter "f"):
1f) participation in the formation of the type of power of the combustion chamber of the furnace (hearth-upper power, upper power, etc.) from ten possible types of power,
2f) participation in the formation of the size of the power of the combustion chamber of the furnace (2.0 kW, 1.6 kW, etc.) of the six possible power sizes,
3f) participation in the formation of the location of the combustion chamber of the furnace (structural location, upper place, etc.) of the ten possible locations of the combustion chamber,
4f) participation in the formation of the location of the chamber of ignition (structural location, nadpodovogo place, etc.) of the five possible locations of the chamber of ignition,
5f) participation in establishing the number of multi-level adjustable multi-function sliding-sliding burners for cooking hot food in dishes simultaneously on different-level rings (simultaneously six floors of rings, simultaneously five floors of rings, etc.) of six possible options,
6f) participation in establishing the type of the indicated multi-level burners for cooking hot dishes in dishes at the same time on different-level burners (on the middle and upper burners, on the upper and on the middle burners, etc.) from dozens of possible options, namely, from the number of combinations of six elements, two elements, three, four, five, six elements each,
7f) participating in the determination of the location of the removable continuous sheet of a customizable multifunctional lift-lowering sliding-sliding hearth (structural place, nadodovoe place, etc.) of the five possible locations.

 The adjustable multi-function multi-storey sliding-sliding burners have the functions 1f, 2f, 3f, 4f, 5f, 6f, 7f.

 The customizable multifunctional removable solid sheet lift-lower sliding-extendable under has the functions 1f, 2f, 3f, 4f.

 The action (operation) of the Rouenka furnace with the setting based on the use of the required menu of hot food dishes, the menu of the types of utensils available for preparing hot dishes, the menu of the types of power of the combustion chamber of the Rouenka furnace, the menu of sizes of the power of the combustion chamber of the Rouenca furnace and others listed above the menu on the example of cooking food outdoors on a summer cottage is as follows.

 A menu is prepared for the upcoming intake of hot food: for example, for an afternoon snack for three people, the menu includes scrambled eggs and coffee.

 From the available dishes, dishes suitable for preparing this hot food are selected: standard (unlike the analogue closest to the invention) a frying pan with an external diameter of 180 mm for eggs and a pan with an external diameter of 145 mm with a capacity of 1.5 liters for coffee.

 The required type and size of power are determined from six possible power sizes (instead of the three power sizes of the analogue closest to the invention) of the combustion chamber based, firstly, from the outer diameter of the selected cookware for cooking hot food, and secondly, from the fact that dishes with food should go down to the burning firewood as they settle in connection with burning out, and, thirdly, by the time the last (in this case, the second) hot dish - coffee - is finished, the firewood and coal from them should completely burn .

 The diameter and height of the selected pans and pans allow you to use a more economical type of power - constant under-power - due to the possibility of simultaneous multi-storey setting of several dishes with food in the firebox (instead of the single-storey setting in the analogue closest to the invention).

 From many years of experience, it is known that for cooking the marked two hot dishes in the Rouenka furnace, a combustion chamber power of 0.8 kW is necessary and sufficient, that is, a combustion chamber with a height of 108 mm (in this case with a hearth-average power) with a one-time ( that is, without subsequent additions) filling these 108 mm with wood.

 A removable front damper 2 is removed from the removable over-column firebox 1 of the furnace 2. Firewood is placed on the combustion chamber from above, which is most convenient, or from the front through an extremely wide opening (in the analogue closest to the invention, there is no extremely wide opening) to a fixed fixed grating below the height 108 mm, that is, to the rods of the sub-middle (that is, the third from the bottom) burners (in the analogue closest to the invention, there is not a single burner).

 Next, two fixed movable rods (about 1/3 of the distance between them) of the middle (i.e., third from the bottom) burner are shifted towards each other and the frying pan is pushed onto it in front. Thus, the desired reduced power of the combustion chamber is obtained by a simpler action compared to how it is done in the analogue closest to the invention. Also, two fixed movable rods of the middle (that is, the fourth from the bottom) burners are shifted to each other and a pot of water for making coffee is placed on top of it.

 Thereby, the arrangement in the solid fuel firebox of two dishes with food at the same time on different-floor burners of two floors is used, which gives an increased efficiency in obtaining thermal radiation from dishes with food in comparison with the analogue closest to the invention.

 Then, a removable sheet under (floor) is removed (in this case, the ash from the previous furnace of the furnace is semi-automatically and non-transportally dumped into the ash collector until ash is accumulated in it to a volume of 36 liters, which is not in the analogue closest to the invention). This does not require (as in the analogue closest to the invention) labor costs for scrubbing ash after several fires from the furnace, pouring ash into a bucket and carrying the bucket to the place of accumulation as a stock of valuable and scarce potassium-calcium-phosphorus-magnesium fertilizer and / or means of controlling pests and diseases of garden plants before the accumulation of wood ash in the ash column of the furnace in a volume of 36 l.

 After that, the ignition chamber (which is not found in the analogue closest to the invention) is easily inserted (like a hot knife into the oil) and then the paper is ignited. As it burns out, additional paper is pushed in to obtain stable burning of firewood in the combustion chamber.

 Further, a removable sheet under (floor) is pushed under a non-removable fixed lattice under (floor) of the combustion chamber, which is at the same time a smoke chamber, including its combustible fractions (i.e., combustible gases and volatile combustible soot emitted during combustion) .

 Due to the fact that the firewood parallelepiped in the firebox is in an air jacket, which is also the place where the combustible fractions of smoke are afterburned, the flame covers the firewood parallelepiped not from one bottom side (as in the analogue closest to the invention), but at the same time all (that is, from six) sides, which gives an increased efficiency for the release of thermal radiation in the combustion chamber and its increased power.

 After removing the frying pan with the finished scrambled eggs from the middle (i.e. the third from the bottom) burner with one hand, the pan of water rises from the middle (i.e., the fourth from the bottom) burner, with the second hand, using the poker, the rods of this burner are extended to the front and rear walls of the firebox, and the pan with water drops to the lower (lower than the frying pan with fried eggs) middle (i.e. third from the bottom) burner, i.e. closer to the flame of burning firewood, with a simpler action compared to how it is done in the analogue, the most close to the invention.

 After a few minutes, as soon as the burner settles to the level of the under-the-top (i.e. second from the bottom) burner, the pan with water similarly acts with the sub-middle (i.e. third from the bottom) of the burner drops even lower - onto the above-water (i.e. second from the bottom) burner to warm to a boil.

 During furnace combustion, after ash is filled with the entire space from the removable sheet hearth to the fixed trellis hearth of the ash combustion chamber, by simply juggling the removable sheet hearth, it is automatically and non-transferringly dumped into the ash collector column, which gives increased efficiency for the release of thermal radiation in the combustion chamber (rather than accumulating in the combustion chamber, as in the analogue closest to the invention, during the entire time the furnace burns, it prevents the access of oxygen to the lower layer of firewood in the combustion chamber, as a result ate what is their incomplete combustion, i.e. so-called mechanical incomplete combustion, which lowers the separation efficiency of the thermal radiation of the combustion chamber).

 If during the preparation of coffee it was not possible to avoid explosive boiling of coffee and some of it accidentally “escaped” from the pan, then it is not necessary to clean the outer upper horizontal and vertical walls of the firebox from the coffee, because the “escaped” coffee will not fall onto the outer walls of the firebox as in analogue closest to the invention, and into the free space of the combustion chamber between the standard cylindrical pan on the burner and the square internal horizontal section of the combustion chamber.

 The Rouenka oven is a universal oven in several respects: it provides the preparation of hot food in any dishes, on any skewers; works at any size (out of six sizes) of power in kilowatts; provides kindling of firewood and putting firewood on either side of the horizon (from two sides); It works at any time of the year, including when using the stove on its own land in winter it does not require digging up snow, since the removable overhead column firebox of the stove is at a height of 490 mm above the ground level, which, for example, in the Moscow Region, exceeds the largest snow cover thickness.

 Technical results of the Rouenka furnace (these results are indicated by the letter "p").

 1r. Increased efficiency in the generation of thermal radiation in the combustion chamber from burning combustible smoke fractions due to the intake of air oxygen from the air jacket around the combustion chamber not only to the lower side of the volume of firewood and volatile combustible smoke fractions in the combustion chamber as in the analogue closest to the invention but also to the upper, front, back, left, right (that is, simultaneously to all) sides of the volume of firewood and volatile combustible fractions of smoke in the combustion chamber, and due to this, afterburning of volatile combustible fractions of smoke in the middle and especially in the upper part of the combustion chamber, in the upper part of the air jacket around the volume of firewood and in the upper part of the firebox (that is, increased efficiency due to the so-called chemical burning of volatile combustible fractions of smoke, which are combustible gases and volatile combustible soot emitted during burning of wood substances).

 2 p. Increased efficiency in obtaining thermal radiation from dishes with food due to lower heat losses due to direct contact (contact) of the flame of burning wood and burning coals not with highly heat-conducting (i.e., highly heat-consuming) steel walls of the firebox as in the analogue closest to the invention, but with highly heat-insulating (that is, with a highly heat-saving) air jacket (more precisely, with an air-smoke jacket), in which there is a trellised basket of the combustion chamber.

 3 p. Increased efficiency in the generation of thermal radiation in the combustion chamber from burning wood in it due to the fact that ash does not remain in the combustion chamber during the entire furnace time and therefore does not interfere with the access of oxygen to the lower layer of firewood as in the analogue closest to the invention, but it falls through the sparsely located rods of a fixed fixed trellis hearth onto a removable continuous sheet under; therefore, the firewood of the lower layer is burned in the combustion chamber (i.e., the increased efficiency due to the so-called mechanical burning of firewood lower th layer).

 4 p. Increased efficiency in obtaining thermal radiation from dishes or skewers with food or wood when they are dry due to the location of any dishes (for example, pans and pots) in a solid fuel firebox at the same time on multi-level burners of several floors (up to six floors of dishes) or rows of skewers with food on multi-storey rods of several floors (up to four floors of rows of skewers with three skewers in each floor) or laying firewood in the firebox for their drying at an altitude as close as possible to dying coals (namely, at an altitude of only 70-100 mm from dying coals). In the analogue closest to the invention, it is possible to place in the firebox only a non-standard food tank and only one floor.

 5 p. Increased efficiency in the production of thermal radiation from dishes whose outer diameter is greater than the length and width of the internal horizontal square section 200 x 200 mm of the combustion chamber, due to the possibility of lifting a removable continuous sheet hearth with burning coals (which are mainly solid carbon, the combustion of which gives as you know, the largest amount of thermal radiation for the entire burning time of a particular portion of firewood in the combustion chamber) to the bottom of the dishes with food to the upstream one of the sliding-sliding closest to this bottom GOVERNMENTAL burners.

 6 p. Increased efficiency in obtaining thermal radiation from utensils with food in the combustion chamber from burning wood in it in the presence of wind in connection with the drying of firewood in this chamber during the period from laying firewood into the combustion chamber after the end of the previous preparation of hot food to the ignition of these firewood for subsequent cooking hot food due to the removal of a removable front flap and a removable rear wall for a specified period of time, and due to this an additional rectilinear horizontal traction (horizon dry draft) and thereby reduce heat absorption at the stage of drying (and heating) firewood when they are burned for the specified subsequent preparation of hot food.

 7 p. Increased efficiency in the generation of thermal radiation in the combustion chamber due to increased afterburning of volatile combustible smoke fractions (i.e., increased chemical burnout) due to the increased performance of the firebox chimney (in cubic centimeters of smoke per minute) relative to the volume of the combustion chamber (the performance of the chimney is also called the smoke exhaust intensity, smoke flow or smoke draft).

There is a chimney near the Rouenka furnace, that is, the space between the square internal horizontal section of the lattice basket of the combustion chamber (20 x 20 cm = 400 cm ² ) and the standard pan lowered into it with a cylindrical wall with an external radius of 10 cm (3.14 x 10 x 10 cm = 314 cm ² ), in the form of a fraction of the internal horizontal section of the lattice basket of the combustion chamber, is not less than (400 - 314 cm ² ): 400 cm ² = 21.5%.

 In fact, this fraction is even larger due to the fact that the Rouenca furnace has eight smoke-filled anti-ash vertical ribside windows that continuously accompany the entire vertical of smoke rise in the firebox.

The marked vertical windows at the stage of drying and kindling firewood work as an addition to the chimney (i.e. smoke exhaust), when an increased amount of smoke is generated due to the still slow burning (decay) of the firewood and increased formation of water vapor. (At the next stage - at the stage of intense combustion with the release of combustible gas and volatile combustible soot - the eight smoke-filled anti-ash vertical ribs open to suck in additional air to burn out that part of the combustible gas and volatile soot substances that lacked oxygen, entering through the lower windows of the firebox.)
In addition, the proportion under consideration is even greater, the smaller the radius of the dishes lowered into the furnace of the furnace, which is not in the analogue closest to the invention.

 8 p. Increased in comparison with the analogue closest to the invention, the power of the combustion chamber due to the increased productivity of the chimney of the firebox (in cubic centimeters of smoke per minute) relative to the volume of the combustion chamber.

 9 p. Increased in comparison with the analogue closest to the invention, the power of the combustion chamber with the same volume due to the fact that the volume of firewood from all (i.e., six) sides and the volume of combustible smoke fractions in the combustion chamber are located in an air jacket and therefore burn simultaneously not only from one (lower) side, as in the analogue closest to the invention, but also from the upper, front, back, left, right sides. Thus, thermal radiation is emitted in the combustion chamber not by one side, but simultaneously by all six sides of the volume of firewood and the volume of combustible fractions of smoke in the combustion chamber, that is, thermal radiation of increased power is released.

 10 p. Increased number of power sizes.

 The same Rouen’s furnace has not three sizes of power of the combustion chamber as an analogue closest to the invention, but six sizes of power (moreover, with a more significant interval (0.3-0.4 kW) between adjacent ones, i.e. closest to each other, dimensions of the power of the combustion chamber) due to the fact that it has five floors of retractable burners and one (first) floor - a burner in the form of a fixed fixed trellis hearth of the combustion chamber, and, in addition, due to the possibility of sliding a removable continuous sheet hearth (gender) to any of the six burners.

 11p. The use of not one non-standard digestion tank and one non-standard lid-pan, as in the analogue closest to the invention, but any (including standard) dishes or skewers with food due to the fact that each pair of front and rear rods of the same on the same floor of the trellised basket of the combustion chamber, when shifted to each other, they form a burner under any dishes, and when extended, under any skewers.

 12 p. Elimination of labor costs for cleaning the outer surfaces of the vertical walls (front, back, left, right) of the firebox from accidentally escaping liquid food (soup, porridge, mushrooms, milk, jelly, etc.) from the cookware due to its explosive boiling compared with an analogue closest to the invention, because in the Ruenka furnace this liquid food is dumped into the free space (in the chimney) of the firebox between the usually cylindrical standard cookware on the burner and the square internal horizontal opening (section) of the combustion chamber.

 13 RUR When using the furnace outdoors on a personal plot of land, eliminating, in comparison with the analogue closest to the invention, a “traveling furnace”, the labor costs (before the accumulation of wood ash in the ash column of the furnace in the amount of 36 l) dozens of racks of ash from the furnace, dozens sprinkling of ash into a bucket and dozens of carryings of a bucket of ash to a place of storage of wood ash as a valuable and scarce potassium-calcium-phosphorus-magnesium fertilizer and a means of controlling pests and diseases of garden plants due to the presence of a removable ash column in the form of a stand for a removable over-column firebox of the furnace.

14 p. Increased comfort, the components of which are further described in the sequence of stages of the furnace maintenance technology and / or its operation:
14.1p) increased comfort for obtaining the desired reduced fuel capacity, that is, reduced power, of the combustion chamber (the maximum power of the combustion chamber, equal to 2.0 kW in the Rouenka furnace, is not always necessary) compared to lowering the entire upper half of the furnace body with non-standard with a food tank in the firebox of the furnace in an analogue closest to the invention, since this decrease in power is carried out either by simply shifting to each other one pair (front and rear) of the rods of the desired floor of the trellis basket of the cell mount or by at least a simple lifting of a removable continuous sheet hearth on one of the higher burners,
14.2p) increased comfort of filling the fuel into the combustion chamber due to the possibility of filling the fuel not only in front and on top, as in the analogue closest to the invention, but also in the back (which is most convenient when adding additional fuel in case smoke is interfering with the front due to wind blowing to the back of the furnace),
14.3p) the increased comfort of filling the fuel into the combustion chamber compared to filling the fuel through the front door in the analogue closest to the invention, due to the fact that each hole (of three holes) for such a bookmark is expanded to the limit, namely, to the perimeter of the ribs (from the angle 25 • 25 • 4 mm) of the corresponding side of the firebox frame by replacing the outer two hinges and the external lock of the front door of the combustion chamber with one internal hinged hook on the removable front shutter (the same hook is used on the removable door days wall), as well as by separating ash retarding threshold (the front door) of the enclosure of the firebox, to transfer this threshold removable sheet under firebox combustion chamber and taking out the removable sheet continuous hearth of the firebox of the furnace before fuel combustion chamber in a bookmark,
14.4p) increased comfort of fuel ignition due to the fact that the place in the combustion chamber intended for a removable continuous sheet hearth and which is the lower part of the air jacket around the volume of firewood in the combustion chamber, when a removable continuous sheet hearth is removed, is used as a space for fuel ignition, then there is the upper half (18 mm high) of the ignition chamber, which is not in the analogue closest to the invention, and the presence of which kindling the furnace from an uncomfortable (painful) operation makes it pleasant and Ecological. The total height of the ignition chamber is 36 mm,
14.5p) increased comfort of fuel ignition in the combustion chamber in the event of wind in the direction of the removable rear wall of the firebox, namely, a decrease in the duration of such ignition by simply removing the removable rear wall (in the analogue closest to the invention, the rear wall of the combustion chamber is non-removable),
14.6p) increased comfort of lowering food to burning wood as it settles due to burning out compared to lowering the entire upper half of the furnace body with a non-standard food tank in the analogue closest to the invention, since the noted lowering in the Ruenka furnace is carried out by simply rearranging ordinary standard dishes with food from the burner of one floor to the burner of the lower floor,
14.7p) when using the stove outdoors on a personal plot of land, the furnace is more comfortable in servicing (removing and hinging a removable front door and a removable rear wall; installing and reinstalling burners; filling fuel into a combustion chamber; removing a removable continuous sheet hearth and moving it to the desired floor ; installation on / in the firebox, servicing and cleaning dishes or skewers with food; laying (sliding) paper into the firebox of the firebox, etc.), namely, a person does not need to bend down, squat, kneel, etc., so control parts of the firebox and its most frequently serviced nodes (handle of a removable front flap, handle of a removable back wall, burners, combustion chambers, removable continuous sheet under, dishes or skewers with food in the firebox, fire chambers of a firebox, etc.) are located on a comfortable for an adult a person of average height, 600-800 mm high from the ground level, and when using the stove on camp, that is, when using the removable over-column firebox of the furnace as a separate independent furnace, it has a height in the working position of 420 m from the ground level.

 Moreover, the analogue closest to the invention has a less comfortable height in the working position of 350 mm from the ground level.
