The combustion furnace adopts the biomass molded fuel and sticks as main fuel, the fuel is adequately combusted, the heat efficiency is high, the combustion can last for a long time after one-time feeding, energy conservation and environmental protection can be realized, and the civil biomass half-gasification combustion furnace is particularly suitable for households in north of China to use.

Description

Civilian biomass semi-gasification combustion furnace

Technical field

It is the combustion furnace of fuel with living beings such as stalk, branch bavins that the utility model relates to a kind of, particularly has the civilian biomass semi-gasification fuel-fired furnace of multiple functional unifications such as heating, cooking and warm 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.China mountain area branch bavin resource is very abundant in addition, makes full use of also and can alleviate energy pressure.But traditional directly make the combustion furnace unreasonable structure of fuel with stalk, branch bavin, efficiency of combustion is low, pollutes more seriously, and function singleness can't satisfy the needs of northern peasant household life with ability.

Summary of the invention

The purpose of the utility model provides a kind of civilian biomass semi-gasification combustion furnace, to satisfy the needs of the cooking of northern peasant household, heating, warm a heatable brick bed.

The utility model combustion furnace comprises body of heater, burner hearth, fire grate, airduct, loading hopper and cooking mouth; It is characterized in that said burner hearth upper end is provided with gathers burner; Gather between burner and the cooking mouth and be provided with half gasification combustion chamber, said half gasification combustion chamber links to each other with logical a heatable brick bed mouth, and said body of heater periphery is provided with water jacket.

Be provided with fire blocking plate between said half gasification combustion chamber and the logical a heatable brick bed mouth.

The said burner that gathers is evenly distributed with a plurality of wind distributing holes that communicate with airduct, and the air inlet of said airduct is provided with by-pass cock.

Said fire grate below is provided with ash accumulating chamber.

Said airduct links to each other with adjustable speed fan.

Said gathering is provided with fire-collection ring or fire blocking plate on the burner.

It is fuel that this combustion furnace utilizes stalk, branch etc., and half gasification combustion chamber makes full combustion of fuel through twice aeration, and water jacket can absorb the body of heater heat, produces hot water, and fume afterheat can lead to the hole heating, significantly reduces heat loss, improves the thermal efficiency.In sum, this combustion furnace sufficient combustion, the thermal efficiency are high, environment friendly and pollution-free, and energy-conservation environmental protection again is particularly suitable for northern medium and miniature flat family and uses.

Description of drawings

Fig. 1 is the structural representation of this combustion furnace.

Among the figure, 1, logical a heatable brick bed mouth, 2, water jacket, 3, water pipe, 4, fire blocking plate; 5, cooking mouth, 6, half gasification combustion chamber, 7, gather burner, 8, body of heater, 9, loading hopper; 10, twice aeration hole, 12, burner hearth, 13, fire grate, 14, cleaning door; 15, ash accumulating chamber, 16, air inlet, 17, blower fan, 18, airduct.

The specific embodiment

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

Referring to Fig. 1, the utility model combustion furnace comprises main furnace body 8, reinforced storage bin hopper 9, burner hearth 12, half gasification combustion chamber 6, ash accumulating chamber 15, air passage portion 18, water jacket part 2.Loading hopper 9 is connected with burner hearth 12, and burner hearth 12 communicates up and down with half gasification combustion chamber 6, and half gasification combustion chamber, 6 upper ends are provided with cooking mouth 5, half gasification combustion chamber 6 backs and link to each other with logical a heatable brick bed mouth 1.Fire grate 13 is equipped with in burner hearth 12 belows, and fire grate is provided with ash accumulating chamber 15 13 times.In gathering burner 7 places, establish interlayer, even distribution twice aeration hole 10 on the inwall of interlayer; Interlayer is connected by wind channel tube 18 with the outside air inlet 16 of body of heater, and air inlet 16 connects small-sized fan 17 and is used for air feed.Body of heater periphery and logical cigarette position are provided with water jacket 2; Burner hearth 12 position of overdoing all uses fire clay 11 envelopes to be coated with.

During the work of this combustion furnace, in reinforced storage bin hopper 9, add biomass molding fuel, fuel falls in the burner hearth 12 through loading hopper 9 end openings.Light the fuel in the burner hearth 12 with burning things which may cause a fire disaster, start blower fan 17 simultaneously, the switch of adjustment air inlet 16 is sent into air in burner hearth 12, and air gets into burner hearth 12 through fire grate 13; After treating fuel combustion, promptly in combustion chamber 12, produce a large amount of fuel gas, this gas gets into half gasification combustion chamber 6 through gathering burner 7.Wall portion gathering burner 7 is evenly distributed with air vent 10, ventilates in gathering burner 7 through natural wind or blower fan 17, plays the combustion-supporting effect of secondary.The fuel gas that accumulates in burner 7 places reaches finite concentration can be lighted, and fully burning under the combustion-supporting effect of secondary air feed, fire blocking plate 4 is transferred to perpendicular position after gathering burner 7, cuts off the path of logical a heatable brick bed mouth 1, makes flame upwards gather fire and is used for cooking; Cooking finishes, and fire blocking plate 4 is transferred to level, and flame is taken out to logical a heatable brick bed mouth 1, and flue gas heat is absorbed by water jacket 2, water pipe 3 (heating water pipe) simultaneously, is used for heating; The waste heat flue gas gets into the flue of a kang through logical a heatable brick bed mouth 1, is used for warm a heatable brick bed, and last flue gas passes through flue row to outdoor.The ashes that the fuel afterburnt produces are settled down to ash accumulating chamber 15 downwards, can be from cleaning door 14 cleaning ash discharges.

Said gathering on the burner can be provided with removable fire-collection ring or fire blocking plate according to functional requirement.
