The device adopts the fashion of down draft combustion and positive combustion alternately. The device can burn honeycomb briquette of the bituminous coal and the anthracite coal. When burning bituminous coal honeycomb briquette, the device can obtain smokeless emission, and the exhaust smoke blackness obtains below lingemann one level. The utility model has the advantages of high speed, simple structure, convenient operation, good fire sealing performance, and few ash and carbon residue. The device is added with coal from upper part and is discharged ash from lower part, the warming heat efficiency is more than 70%, saves the coal to 30%, and is suitable for warming and cooking for south and north families, and is convenient to actualize.

Description

Domestic heating device

The utility model relates to a kind of family life heating installation, and this installs in same body of heater, alternately adopts the down draught burning, is just burning two kinds of modes of burning and is constituting.

Heating installation does not in the market possess at the two ends of flue kiss and connects two combustion chambers, and an end of chimney becomes these two combustion chambers of cross-over connection of " F " type.

A kind of down draught burning domestic burners patent that the utility model has been applied for from the applicant.(ZL85203854) this stove utilizes the down draught burning that the flue gas of high-volatile bituminous coal effusion is fully burnt, and makes the blackness of exhaustion normal condition that emits below the Lin Geman one-level, satisfies the requirement of the clean clean method of air.By the application over 2 years, down draught burning also still has other defect, and after for example eliminating smoke, Honeycomb briquet is wanted inversion, and it is highly big that flame hangs fire, operates more numerously, and the heat energy utilization rate is on the low side.

The purpose of this utility model is to overcome the shortcoming of known down draught burning domestic burners, a kind of domestic heating device is provided, the flue gas that had both allowed its keep down draught burning that high-volatile bituminous coal is overflowed fully burns, and the blackness of exhaustion that ejects reaches and uses the bituminous coal smokeless emission below the Lin Geman one-level.The simultaneous adaptation common people's traditional habit adopts upper coal feeding, following ash disposal; The speed of getting angry is fast, and the performance of banking up a fire is good, and lime-ash carbon residue is few, and apparatus structure is simple, and is easy to operate, and heating efficiency can economize on coal 30% more than 70%.

Above-mentioned purpose can reach like this: in the accompanying drawing, the upper end of flue (4) is provided with a upper combustion chamber (2), the lower end of flue (4) is provided with a lower combustion chamber (5), and an end of chimney becomes these two combustion chambers of " F " type cross-over connection, is provided with in " F " type stovepipe and switches air door (7); Secondary air channel (3) is set between burner hearth and flue, and is communicated with upper and lower two combustion chambers; Top at device is provided with air inlet on (1), in the bottom of device a following air inlet (6) is set.The moulded coal that this device is firing is in the below of flue (4), not kindling on fire coal, when need eliminating smoke, close down air inlet (6), air inlet in the unlatching (1), along with the effect of chimney negative pressure and switch (7) cooperate, the top not emit cigarette after the kindling preheating, plume is met a high temperature after-combustion through the coal-fired layer of below and is entered lower combustion chamber (5), under the cooperation of secondary wind, in lower combustion chamber's burning that eliminates smoke fully, at this moment, whole device is in the down draught fired state.Smoke elimination finishes, and closes air inlet (1), opens air inlet (6) down, and flame burns in upper combustion chamber.At this moment, whole device is in positive fired state, and this heating installation not only can be warmed oneself, but also double as cooking at the fugitive constituent that carries out only burning when down draught burns coal, is burnt the fixed carbon of coal when just burning burning.The fixed carbon heat accounts for 4/5ths of coal net quantity of heat, and heat is enough.

Secondary air channel (3) is for exchanging air intake, during the down draught burning, secondary wind from top to bottom, when just burning since the draft direction change, secondary wind automatic reverse, from the bottom to top.

The application object is compared with known heating, cooking stove has advantage: this device is subjected to the limitation of coal little, and bituminous coal, anthracite can both burn, and particularly utilizes the down draught burning, can reduce overflowing of pernicious gas; Reached the purpose of protection environment.Simultaneously can select the burner hearth and the honeycomb briquette of different size for use according to the size of heating area, apparatus structure is simple.

Accompanying drawing is a cutaway view of the present utility model.

The utility model technical parameter:

The thermal efficiency＞70%

The performance of banking up a fire: 1 kilogram of coal (calorific value 4500 kilocalorie/kilograms) was banked up a fire more than 16 hours.

Coal saving rate＞25%(and old Beijing formula cast-iron stove are relatively)

0 grade of smoke density: Lin Geman (the igniting initial stage is not more than 1 grade)

The flue prescription:

The ripe aggregate of alumina: the ripe powder 30% of 60% alumina

Fire clay: 10% aluminum phosphate solution an amount of about 8%

Above-mentioned prescription also is adapted to down gas combustion chamber (5).

Embodiment of the present utility model:

The furnace shell of body of heater can roll with the cold-rolled steel sheet of δ=0.5mm in the accompanying drawing, also available cast iron casting, stove overall height 400mm, diameter 280mm.But flue air register (7), top cover labyrinth plate, revolve hot boiler face, heat collector panel, all cylinder iron casting, thickness is not more than 3mm.

Adopt expanded perlite, aluminosilicate fiber cotton insulation, insulation thickness 80mm, flue interior diameter 120mm, high 210mm, flue establish 6 fins.

Two secondary air channels (3) diameter 20mm, long 220mm fires with refractory material.Ash discharge reaches shutter (6) external application metal material down, and interior is thermal insulation coatings, and diameter is 60mm.

Following gas combustion chamber (5) is used the fireproof coating ramming.

Claims (2)

1, a kind of domestic heating device, in body of heater, be provided with furnace wall, flue, combustion chamber, secondary air feed system and chimney are formed, use bituminous coal and be smokeless emission, technical characterictic of the present utility model is to connect two difform combustion chambers at inner of the boiler chamber courage two ends kiss; And an end of chimney becomes " F " type to be connected across this two combustion chambers, and secondary air channel is connected two combustion chambers again.

2, heating installation according to claim 1 is characterized in that being provided with in chimney and switches air door.
