Abstract
The utility model relates to a spiral flow type two-purpose coal stove for cooking and heating, which is mainly composed of a stove body, a stove tile, a grate, a water jacket, a water inlet, a water outlet, a fire sealing ring, a fire shielding ring, an inner stove cover, etc. The utility model is characterized in that an annular spiral flow type heat absorbing section is arranged on the inner wall of the water jacket of the upper part of a stove chamber and is composed of a plurality of spiral heat absorbing sheets. Because the utility model is provided with the spiral flow type heat absorbing section to force smoke to form rotary motion in the spiral flow type two-purpose coal stove for cooking and heating, the utility model enhances the contact and the friction for the heating surface of the water jacket, effectively prolongs the staying time of the smoke in the utility model, enhances a heat exchanging effect and obviously reduces smoke discharging temperature under the condition of not increasing the height of the stove body.
Description
The utility model relates to a kind of residential coal combustion stove, relates in particular to a kind of family expenses cooking, the dual-purpose coal furnace of heating.
The family expenses cooking of using in the prior art, the coal-fired dual-purpose stove of heating roughly have following three kinds: a kind of is except that water jacket itself, and upper furnace does not increase any heat-absorbent surface, and flue gas is directly discharged from chimney.This kind type of furnace is when baked wheaten cake is prosperous, and exhaust gas temperature can be up to more than 600 ℃, and heat loss is big, causes the thermal efficiency to descend.Second kind is to be added with water jacket on chimney, is used for absorbing the heat of flue gas to reduce exhaust gas temperature.Though this kind stove improves to some extent than the above-mentioned type of furnace, there are following two problems: the one, because chimney water sleeve and body of heater connect together, cause the manufacturing processed complex, transportation inconvenience and installation difficulty etc.; The 2nd, when flue gas flows,, and form the dead gas-bearing formation of one deck because the fast edge of center flow velocity flow velocity is slow in chimney, the centre still has high-temperature flue gas to discharge, so when baked wheaten cake was prosperous, also more than 400 ℃, heat loss was still bigger for exhaust gas temperature; The third is to set up heat absorbing sheet on the water jacket inwall of upper furnace, this heat absorbing sheet is owing to can play the prolong smoke time of staying and the effect of increase endotherm area, thereby can reduce exhaust gas temperature preferably and improve the thermal efficiency, be use the coal-fired dual-purpose stove of more a kind of novel household in the present prior art, for example Chinese utility model patent 87216128 is exactly wherein a kind of.But the shortcoming that exists is, because the heat absorbing sheet flexibility is little, and vertical the layout, if reach the purpose that reduces exhaust gas temperature significantly, just must increase the quantity and the height of heat absorbing sheet, this will cause body of heater to increase and sheet and sheet between spacing too small, to cooking and burn bituminous coal bring unfavorable.
The purpose of this utility model is deficiency and the defective that exists at prior art, a kind of cyclone-type cooking, the coal-fired dual-purpose stove of heating are provided, this coal furnace can not only prolong the time of staying of high-temperature flue gas in stove effectively, further strengthen heat exchange, reduce exhaust gas temperature, improve the coal-fired thermal efficiency, and can both obtain good effect different coals.
The utility model is achieved by the following technical solution: it mainly is made up of parts such as body of heater, tile, grate, water jacket, water inlet, delivery port, fire-sealing ring, inner roof brick, shelves fire tubes, it is characterized in that being provided with on the inwall of upper furnace water jacket annular eddy flow endotherm section, this annular eddy flow endotherm section is made up of multi-head spiral shape heat absorbing sheet.
Owing to installed annular eddy flow endotherm section additional, force flue gas to form in stove and rotatablely move, the rotation of flue gas has strengthened the contact of water jacket heating surface and friction, makes the time of staying of high-temperature flue gas in stove further prolong, thereby strengthened heat exchange effectively, improved the coal-fired thermal efficiency.
In order to reduce the flue gas short circuit, increase flue gas resistance, near the water jacket inwall the chimney porch, except that microscler spinning disk is set, also increased the brachmorphy spinning disk.
On the basis of the above, in order further to improve coal-fired burn-out degree, avoid the upper furnace anoxic, reduce the loss of carbon monoxide, between tile and water jacket, set up a secondary air channel road, can make secondary wind suck the anoxic zone of upper furnace from grey chamber like this, help promoting the burning of volatile combustible matter, further improve efficiency of combustion.
Description of drawings:
Accompanying drawing 1 is a structure diagram of the present utility model.
Accompanying drawing 2 is the A-A sectional drawing of accompanying drawing 1, expresses the microscler spinning disk and the deployment scenarios of brachmorphy spinning disk on the water jacket inwall of annular eddy flow endotherm section.
Accompanying drawing 3 launches schematic diagram for spinning disk.
Describe concrete structure of the present utility model and embodiment in detail below in conjunction with accompanying drawing.
The utility model is mainly by body of heater 1, tile 2, and grate 3 is contained in the water jacket 4 of burner hearth inside, annular eddy flow endotherm section 5, water inlet 6, delivery port 7, fire-sealing ring 8, firestopping tube 9, inner roof brick 10, secondary air channel 11 parts such as grade are formed.Annular eddy flow endotherm section 5 is contained on the inwall of upper furnace water jacket 4, adopts 45 ° of multi-head spiral shape heat absorbing sheets.Two kinds of microscler heat absorbing sheet and brachmorphy heat absorbing sheets are arranged, and microscler heat absorbing sheet 12 is evenly arranged on the water jacket inwall, and 13 of brachmorphy heat absorbing sheets are contained near the water jacket inwall of chimney inlet.Its length is 1/2 of microscler heat absorbing sheet, and alternate layout with microscler heat absorbing sheet.Stop up exhaust gases passes when avoiding burning bituminous coal, the channel distance between the heat absorbing sheet should not be less than 50 millimeters; The vertical height of eddy flow section is 100 millimeters and is advisable.
The utility model is also set up a secondary air channel road 11 between tile and water jacket, it is that the combustion zone of upper furnace is led in grey chamber below grate, its objective is the burning that promotes volatile fuel, reduces the carbon monoxide loss, further improves the thermal efficiency.
During use, when opening fire-sealing ring 8, cover inner roof brick 10 and firestopping tube 9, thermal-flame and flue gas will all enter chimney by spinning disk again, and the high-temperature-hot-water heating can be provided this moment, can heat up water when not covering inner roof brick and cook, and also can heat simultaneously.If cover fire-sealing ring 8, the heating water temperature still can be kept higher temperature, and this moment, coal consumption was very little.
The utility model compared with prior art has the following advantages and beneficial effect: because in upper furnace Added annular eddy flow endotherm section on the inwall of water jacket, forced flue gas in stove, to form and rotatablely move, and flue gas Rotation strengthened contact and friction to the water jacket heating surface so that the time of staying of high-temperature flue gas in stove advances One step prolonged, and had strengthened heat transfer effect, thereby can make exhaust gas temperature bright in the situation that does not increase the body of heater height The aobvious reduction. Increased secondary air channel and further improved efficiency of combustion, can both obtain very various coals simultaneously Good application is compared with the heating stove that is unkitted heat absorbing sheet, and heating load improves 30%, and 10-20% economizes on coal.
