Description

Domestic biomass gasification combustion-supporting multipurpose furnace
Technical field
The present invention relates to a kind of Domestic stove, the domestic biomass gasification combustion-supporting multipurpose furnace that particularly combines and burn with coal and biomass fuel.
Background technology
There is the problem that coal combustion is incomplete, efficiency of combustion is lower mostly in traditional domestic briquet stove, and not only coal consumption is large, and environmental pollution.In order to save coal resource, simultaneously for the discarded living beings such as a large amount of faggots that produce in rural area, stalk are utilized, various biomass gasifying furnace, half-gasification ovens take living beings as fuel have been developed in recent years, but these stove and accessorys are mostly shorter because of the biomass fuel combustion time, have the shortcoming that needs frequent filling.
Summary of the invention
The object of the present invention is to provide a kind of domestic biomass gasification combustion-supporting multipurpose furnace, it is take coal as basic fuel, the fuel gas that generates take gasification of biomass is as adding fuel, and the coal combustion that overcomes traditional coal stove not exclusively and the defective of the frequent filling of biomass fuel stove need.
Be provided with primary zone, secondary combustion chamber and gasification of biomass storage compartment in the body of heater of multipurpose furnace of the present invention, the bottom of described primary zone and gasification of biomass storage compartment is equipped with fire grate, and the middle part of gasification of biomass storage compartment communicates with the primary zone with through hole; Described secondary combustion chamber is positioned on the poly-burner of upper end, primary zone, the upper end of secondary combustion chamber is provided with the cooking mouth, described poly-burner setting contains the annular wind dish of hollow, the cavity of annular wind dish communicates with the airduct of secondary combustion-supporting, and the internal ring wall face of annular wind dish is evenly distributed a plurality of air-out apertures.
Be provided with water jacket around the described body of heater.
Described secondary combustion chamber connects logical a heatable brick bed flue.
The fuel of this stove and accessory combines with coal and living beings, i.e. the indoor adding coal of primary combustion, and gasification adds biomass fuel in the storage compartment.The biomass fuel of gasification storage compartment is heated under anoxia condition and gasifies, the fuel gas via through holes that gasification forms passes into the primary zone, together to enter second-time burning from poly-burner indoor with the flue gas of the imperfect combustion generation of coal, passes into simultaneously secondary combustion-supporting wind and be able to abundant burning.Gas behind this stove gasification of biomass and coal combustion flue gas are in the indoor mixed combustion of second-time burning; stove fire is more powerful; fuel combustion is lasting; fuel saving; solved the frequent difficult problem of adding of biomass fuel, and the burning situation cleaning, flue dust reduces; protection of the environment can satisfy simultaneously user's heating, cooking, logical a heatable brick bed required.
Description of drawings
Fig. 1 is the structural representation of this stove and accessory.
Fig. 2 is annular wind dish longitudinal profile structural representation.
Among the figure, 1-gasification ash accumulating chamber, 2-water jacket, 3-fire-resistant mud layer, 4-gasification storage compartment, 5-through hole, 6-body of heater, 7-reinforced lid, 8-secondary combustion chamber, 9-cooking mouth, 10-annular wind dish, 10-1-toroidal cavity, 10-2-air-out aperture, 11-hot water outlet, 12-logical a heatable brick bed mouth, 13-primary zone, 14-airduct, 15-cooling water inlet, 16-little blower fan, 17-burning ash accumulating chamber, 18,19-fire grate.
The specific embodiment
Further specify example structure and the operation principle of domestic biomass gasification combustion-supporting multipurpose furnace of the present invention below in conjunction with accompanying drawing.
Such as Fig. 1, comprise the primary zone 13, secondary combustion chamber 8 and the gasification of biomass storage compartment 4 that are built into by fire-resistant mud layer 3 in the body of heater of domestic biomass gasification combustion-supporting multipurpose furnace; The bottom of primary zone 13 is provided with fire grate 18 and burning ash accumulating chamber 17, and the bottom of gasification of biomass storage compartment 4 is provided with fire grate 19 gentleization ash accumulating chamber 1, and the middle part of gasification of biomass storage compartment 4 communicates with primary zone 13 with through hole 5.The poly-burner in 13 upper ends, primary zone arranges annular wind dish 10, and secondary combustion chamber 8 is positioned at the top of annular wind dish 10, and communicates with primary zone 13 by annular wind dish 10.Referring to Fig. 2, annular wind dish 10 is annular hollow structure (namely containing toroidal cavity 10-1), and the internal ring wall face of annular wind dish 10 is evenly distributed a plurality of air-out aperture 10-2, and toroidal cavity 10-1 is by secondary combustion-supporting airduct 14 connecting fans 16.The upper end of secondary combustion chamber 8 is provided with cooking mouth 9, and the logical a heatable brick bed mouth 12 of the sidewall of secondary combustion chamber 8 is used for smoke evacuation and the heating of logical a heatable brick bed.Be provided with water jacket around the body of heater 6, water jacket is provided with cooling water inlet 15 and hot water outlet 11.
When this furnaceman does, 13 interior coal is added in the primary zone first, light, enter natural wind (being a combustion air of combustion chamber 13) by fire grate 18, filling it up with biomass fuel to gasification in the storage compartment 4 (can be the various discarded living beings such as stalk, bavin standing grain, cauline leaf, effect is better after the chopping compacting), then close reinforced lid 7.Light from the fire grate 19 storage compartment's 4 bottom biomass fuels that will gasify, close because of the reinforced lid 7 in upper end, the biomass fuels in the gasification storage compartment 4 are heated gasification under anoxia condition, produce flue gas.Under the draft effect of logical a heatable brick bed mouth 12 outer ends smoke evacuation, gasification storage compartment 4 flue gases enter primary zone 13 by through hole 5, a small amount of flue gas is lighted by the naked light that coal burning produces by 13 upper end, primary zone the time, and a large amount of flue gases together enter 8 interior mixing of secondary combustion chamber with the gas that coal burning produces.Meanwhile, the secondary combustion-supporting wind that little blower fan 16 is sent into is by the toroidal cavity 10-1 of the annular wind dish 10 of airduct 14 inputs, then spray to the interior ring central passage of annular wind dish 10 from each air-out aperture 10-2, and rise immediately, to secondary combustion chamber 8 oxygen-supplying combustion-supportings, fuel reaches completing combustion, the heat of producing is except being used for cooking, also but the water in the heating water jacket 2 is used for heating of house, fume afterheat discharging after logical a heatable brick bed heating.The ashes of burning are fallen into 17 gentleization ash accumulating chamber 1 of burning ash accumulating chamber, are convenient to deashing.This stove combines the persistence of coal burning with the spatter property of gasification of biomass after-combustion, have complementary advantages, and is easy to use, again fuel saving.
