Description

Multifunctional civil biomass fuel combustion stove

Technical field

[0001] the present invention relates to a kind of living beings with moulding such as stalks is the combustion furnace of fuel, particularly has the civilian biomass fuel combustion stove of multiple functions such as cooking, heating, burning a heatable brick bed simultaneously.

Background technology

China is a large agricultural country; Annual about 600,000,000 tons of the agricultural crop straw that produces; Except that being used for the raw materials of industry such as fertilizer, feed, base-material and papermaking, there are 300,000,000 tons of agricultural crop straws still not have the proper process approach at present approximately, therefore; The phenomenon that the on-site incineration stalk has appearred in a lot of areas causes severe contamination to environment.These discarded crop stalks can be amounted to 1.5 hundred million tons of standard coals as using as the energy, and traditional burning straw mode, utilization ratio is low, and pollutes also comparatively serious.Developed at present a kind of shaped fuel of processing with living beings such as stalks; But the existing biomass combustion stove ubiquity thermal efficiency is low, and lacks the multi-functional combustion stove that a heatable brick bed can be warmed oneself, burnt to ability cooking again that has that is fit to the northern area use, in addition; A heatable brick bed burnt with naked light mostly as the civilian a heatable brick bed of doss in the north; Waste fuel, temperature also are difficult to control, and security is relatively poor.

Summary of the invention

The purpose of the utility model provides a kind of northern area that is particularly suitable for and uses, and collects cooking, heating and the burning a heatable brick bed multifunctional civil biomass fuel combustion stove in a stove, and is easy to use, safety, and the thermal efficiency is higher.

The utility model combustion furnace comprises body of heater; Body of heater is made up of combustion chamber and Bunker, and Bunker is provided with charge door, and combustion chamber and Bunker lower end communicate and form burner; Fire grate is equipped with in combustion chamber and Bunker below; Under the fire grate deashing chamber is set, the upper end, combustion chamber is provided with the kitchen range mouth, and top, combustion chamber one side is provided with logical a heatable brick bed mouth.

Said combustion chamber one side is provided with the secondary air distribution outlet.

The kitchen range mouth below of said combustion chamber is provided with gathers burner.

Water jacket is set around the furnace wall of said body of heater.

Said gathering between burner one side and the logical a heatable brick bed mouth is provided with a sideboard that is connected with rotary handle.

Combustion chamber of this combustion furnace and Bunker are the U type and communicate, and the biomass fuel of moulding such as stalk descends in Bunker automatically, burn when arriving the burner of bottom.The fire grate of bottom, combustion chamber can be through going into air intake one time, and it is further combustion-supporting that top secondary air distribution outlet feeds secondary air, makes fuel be able to abundant burning, and the thermal efficiency is high.Bunker can be laid in a certain amount of fuel, extends working time, and is easy to use.This stove also can produce hot water through to the water jacket heating except that as the daily cooking stove; The hot flue gas that burning produces is discharged from chimney behind a heatable brick bed road from logical a heatable brick bed mouth, utilizes flue gas heat to realize warm a heatable brick bed, and temperature is more easy to control, and stable, safety are more comfortable, have overcome the defective of the warm a heatable brick bed of traditional naked light formula.

In sum, this combustion furnace uses biomass fuel, clean environment firendly; Be provided with the secondary air distribution, efficiency of combustion is high; The lower feeding charging, easy to use; Multiple functions such as having cooking, burn a heatable brick bed, the heat supply hydromining is warm is particularly utilized the fume afterheat formula burning that realizes having not been cooked or heated long enough, and is safe, energy-conservation, has very wide application prospect.

Among the figure, 1, charge door, 2, Bunker, 3, fire grate, 4, ash hole, 5, deashing chamber; 6, burner, 7, the combustion chamber, 8, the secondary air distribution outlet, 9, logical a heatable brick bed mouth, 10, water jacket; 11, kitchen range mouth, 12, body of heater, 13, sideboard, 14, rotary handle, 15, gather burner.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to detail:

Referring to Fig. 1, the body of heater 12 of this combustion furnace comprises biomass fuel feed bin 2, combustion chamber 7, fire grate 3 and deashing chamber 5, and logical a heatable brick bed mouth 9 is provided with water jacket 10 around the body of heater.Bunker 2 tops are provided with charge door 11, and kitchen range mouth below is provided with gathers burner 15.Combustion chamber 7 is the U type with Bunker 2 and communicates, and the two connection place forms burner 6.

During the work of this combustion furnace; Open charge door 1 lid, adding biomass molding fuel to Bunker 2 in, fuel upwards is accumulated to when a certain amount of from fire grate 3; With the biomass fuel of 2 bottoms, burning things which may cause a fire disaster fire fuel storehouse, it is full to treat to continue to add biomass fuel to Bunker again after firepower is strengthened.Air upwards carries a wind combustion-supporting through fire grate 3, and from burner 6 entering combustion chambers 7,7 secondary air distribution outlet 8 places obtain secondary air to the high-temperature flue gas of rising to flame in the combustion chamber, and are further combustion-supporting with air-flow.Flame rises in combustion chamber 7 and through gathering burner 15 to 11 ejections of kitchen range mouth, promptly can be used for cooking.Simultaneously, the heat that burning produces is with 10 heating of the water jacket around the combustion chamber 7, and the hot water in the water jacket is used for heating or washing through the pipeline output of body of heater 12.Along with the carrying out of combustion process, fuel is consumed gradually, and because of the gravity effect descends automatically, through the burner postcombustion, the fuel of Bunker can replenish from charge door 1 fuel at any time in Bunker 2.The flue gas that rises through a heatable brick bed road, finally passes through chimney to outdoor discharging from logical a heatable brick bed mouth 9.The ashes that the fuel afterburnt produces are settled down to deashing chamber 5 downwards, can be from ash hole 4 cleaning ash discharges.Strengthen the cooking firepower like need, can sideboard 13 be gone to vertical position through rotary handle 14, flue gas is gathering jet-burner directly upwards to the kitchen range mouth; After cooking finishes (can add a cover), can sideboard 13 be gone to level, make high-temperature flue gas directly feed logical a heatable brick bed mouth 9, improve and warm up a heatable brick bed temperature at kitchen range mouth 11.
