Abstract

The boiler has a combustion chamber (2) for receiving fuel material. The combustion chamber is enclosed by a chamber. Walls of the chamber are supplied with a heat transfer medium (16), which flows through an outlet after heating of the medium. Heating gases (4) produced in the combustion chamber are supplied to a heating surface (23) downstream to the combustion chamber, where flues (26, 27) are diverted in relation to a flue gas stream (34) running in a direction of an exhaust gas furnace (25). The flues exhibit double-walled formation, where inner areas are flowed from the medium.

Thus, for example, when felling trees as lumber, unusable tree trunks are cut into handy pieces that split into logs and are heated after drying. In agriculture, considerable quantities of flammable material are produced, for example as straw when threshing grain. This straw was often burned on harvested fields. As a result, by heating the field crop not only damage to fertile fields, but also caused by a sometimes very incomplete combustion pressures on the atmosphere in particular by CO or CO 2 gases.
  • Logs were burned in chimneys in no small extent. This also caused considerable pollution of the atmosphere, in particular by CO 2 . At a recovery of usable heat was thought at most in connection with wood-processing enterprises, such as carpentry and carpentry. These could burn the wood in industrial furnaces and also pay attention to a favorable design of emerging exhaust gases. In the context of a heat demand, as it exists, for example, in households, so far wood was mainly burned in fireplaces. It could not be thought that the flue gases produced in the respective chimneys were released into the atmosphere in an environmentally compatible manner.

  • Further Details of the invention will become apparent from the following detailed Description and attached Drawings in which a berber preferred embodiment of the invention, for example is illustrated.
  • In show the drawing:
  • 1 : Sketch of an exterior view of a boiler,
  • 2 Image: Top view on a kettle,
  • 3 : Longitudinal section through a boiler according to the section line AA in 2 .
  • 4 : Front view on a cauldron and
  • 5 : spatial view of a boiler with an attached radiator as heat consumer.
  • A kettle 1 consists essentially of a combustion chamber 2 from a chamber 3 is enclosed and a water jacket 8th , This chamber 3 has one in the direction from inside the chamber 3 rising hot gases 4 upward-limiting large-area ceiling surface 5 in the form of a sched roof with successive angles 6 is designed. This design produces a comparatively large heat transfer surface in the direction of one above the ceiling surface 5 provided space 7 who is to a the combustion chamber 2 surrounding water jacket 8th belongs. This room 7 is on his the ceiling area 5 opposite side of a closure surface 9 limited, the upper end of the boiler 1 represents. Through the closing surface 9 protrudes into the room 7 a devolatilizing pipe 10 into it, into an external environment 11 of the boiler 1 is guided. From this devolatilizing pipe 10 may be in the water jacket 8th emerging steam into the environment 11 escape, leaving the room 7 even when the evaporation temperature is exceeded, it remains depressurized.
  • In the water jacket 8th protrudes above the ceiling 5 a hot water connection 12 into it, over a connecting line 13 in a hot water supply 14 a heat consumer 15 opens. This is from a in the heat jacket 8th heated heat transfer medium 16 , usually hot water, flowed through, which in the cooled state by egg NEN DHW drain 17 in a feed line 18 is discharged, with one in the water jacket 8th inflowing inlet 19 connected is. This hot water supply 19 is in the rainfall below a floor 20 of the combustion chamber 2 provided and flows into a lower part 21 of the water jacket 8th one. From this rises the cooled heat transfer medium 16 when heated to the water jacket 8th towards the room 7 above the ceiling area 5 of the combustion chamber 2 and is heated there by the rising hot gases back to the desired temperature.
  • The combustion chamber 2 is via a connection opening 22 a heating surface 23 downstream, through which the hot gases 4 towards an exhaust outlet 24 be passed through. This exhaust outlet 24 is with a flue 25 connected by the in the heating surface 23 cooled exhaust gases in the environment 11 be dismissed. The exhaust stack 25 may have been made of prefabricated components, not shown, and inside have a non-illustrated inner insulation.
  • The heating surface 23 consists essentially of two flues 26 . 27 , in turn, through smoke flow divider 28 . 29 in sub-streams 30 . 31 . 32 . 33 are divided. At the entrance of the flue gases from the connection opening 22 into the flues 26 . 27 finds a right-angle deflection of a flue gas stream 34 instead, so that each parts of the flue gas stream 34 through the partial streams 30 . 31 towards a collector 35 be redirected. In the collector 35 a power divider protrudes 36 into it, by the one through the flue 26 in the collector 35 entering flue gas flow is deflected by 180 °, so that the flue gas flow through the flue 27 towards the exhaust outlet 24 to be led. This is the by the flue 27 directed smoke flow in the direction of the exhaust outlet 24 again deflected by 90 °.
  • This will be the flue gas flow 34 who has the combustion chamber 2 leaves twice by 90 ° and once by 180 °. As a result, the flue gas stream loses both by the deflection and by the leadership in the relatively narrow part streams 30 . 31 . 32 . 33 strong in speed, so in the smoke stream 34 Entrained particulate matter due to the loss of velocity of the flue gas streams in the collector 35 fails and from this via an access 37 can be removed.
  • At the same time, the flue gases in the heating surface 23 even on walls 38 the partial flows 30 . 31 . 32 . 33 and the flow divider 36 considerably cooled, so that also by this cooling the failure of fine dust is favored. This cooling takes place on the walls 38 the partial flows 30 . 31 . 32 . 33 as well as the current divider 36 instead of passing through the heat carrier 16 are cooled, the entire downstream heating surface 23 flows. For this purpose owns the heating surface 23 from the heat carrier 16 traversed interiors, by boundary surfaces 39 . 40 are formed. In addition, the smoke are current divider 28 . 29 and the flow divider 36 from the heat carrier 16 flushed. In this way owns the heating surface 23 one from the flue gas stream 34 on the one hand and from the heat transfer medium 16 On the other hand, the coated heat transfer area of 14 m 2 .
  • The heat carrier 16 can in the water jacket 8th and in the heating area 23 depending on the setting of a tension controller 41 be heated to a desired temperature between 30 and 90 ° C. It is by the tension controller 41 a lot of drafts for burning one in the combustion chamber 12 ignited fuel 42 is needed, so regulated that the fuel 42 either burned vigorously or with reduced heat. With a wide open draft regulator 41 a large amount of combustion air enters the combustion chamber 4 and promotes the combustion of the fuel 2 , This burns at relatively high temperatures, so that on the one hand a lot of heat in the ceiling area 5 to those in the room 7 located heat transfer medium 16 is delivered. Accordingly, even relatively high heated fuel gas occurs 4 in the redesigned heating surface 23 and there gives the heat to the heating surface 23 flowing heat transfer medium 16 from. This can therefore with a high temperature, for example, of 90 ° C, the boiler 1 towards the heat consumer 15 leave.
  • With increasing closure of the tension controller 41 the amount of fuel in the combustion chamber decreases 2 let in draft, leaving the fuel 42 corresponding to the low draft air less lively or even slow burns. This reduces the temperature of the hot gases 4 , which according to the low temperature, only a small amount of heat to the heat transfer medium 16 can deliver. This is heated accordingly low, so that he only with a low temperature in the heat consumer 15 occurs and also heats this only to a small extent.
  • In a similar way, in the combustion chamber 2 even a small amount of the fuel 42 entered. This burns hesitant in view of the small amount of combustion air, so that at long intervals new fuel 42 in the combustion chamber 2 must be inserted.
  • The control of the temperature with which the heat transfer medium 16 the kettle 1 Leaves can also with the help of a thermostat 43 respectively. This thermostat 43 becomes the respectively desired temperature the heat carrier 16 entered. At the same time, the temperature of the heat carrier 16 inside the room 7 sampled. This temperature is compared by the thermostat 43 with the temperature value entered. Depending on whether the temperature of the heat carrier 16 too low or too high in terms of in the thermostat 43 entered temperature value, the thermostat controls 43 the opening of the tension controller 41 until the temperature of the heat carrier 16 in the room 7 has reached the desired height. At this height holds the thermostat 43 the temperature of the heat carrier 16 in the room 7 ,
  • Furthermore, the boiler has 1 on his front 44 another water level glass 45 at which the respective filling state of the room 7 and the heating surface 23 can be read. Will a strong drop in the heat carrier 16 from the water level glass 45 indicated, additional heat transfer medium 16 in the room 7 be fed to overheat the ceiling surface 5 or the heating surface 23 to avoid. The kettle 1 can protect against damage and other environmental influences with a plastic sheath 46 be surrounded for example by polyurethane. With this plastic jacket 46 , which serves as moisture and heat insulation, he is in a housing 47 taken over, with side walls 48 and with a front end 49 is provided and from a roof 50 is covered. From the side area of the boiler 1 protrude the connections for the flow and return to the heat consumer 15 out.
  • In the front part 49 is one with the help of a hand lever 52 lockable firing door 53 provided for fishing 54 is pivotally mounted. After opening the firing door 53 can fuel 42 in the combustion chamber 2 be entered.
  • In addition, in the firing door 53 a fan controller 55 provided by the thermostat 43 is controlled. Also this thermostat 43 controls via a chain via a supply air flap, which is provided in the front area of the boiler, the amount of air flowing to the firing. The fan control 55 has a number of louvers 56 on, as needed by the thermostat 53 be opened or closed. As a result, the amount of air required in each case by the furnace into the combustion chamber 2 entered one at the thermostat 43 to reach set temperature.
