Description

Biomass gasifying furnace combustion chamber

Technical field

The utility model relates to boiler technology field, and especially a kind of take living beings as the biomass gasifying furnace combustion chamber of fuel.

Background technology

The straw produced in agriculture-stock production, branch wood chip, cattle and sheep ight soil etc. all belong to biomass energy.Biomass fuel is widely used as a kind of novel regenerative resource.Compare with coal, the heat of biomass energy unit volume is little, requires larger gasification space and the rational combustion chamber of air distribution as biomass gasification boiler.Lack in prior art for biomass energy design boiler, biomass gasifying furnace combustion chamber is unreasonable, vaporizer and combustion chamber little, air distribution is unreasonable, and the thermal efficiency is low.

Summary of the invention

The purpose of this utility model provides a kind of biomass gasifying furnace combustion chamber for above-mentioned Problems existing, and its structure is simple, easy to use, sufficient combustion, the thermal efficiency are high.

The technical scheme that the utility model adopts is: a kind of biomass gasifying furnace combustion chamber, is characterized in that: it comprises the vaporizer and combustion chamber that are set up in parallel, and vaporizer is communicated with bocca with the bottom of combustion chamber; The bottom of vaporizer is gasification furnace grate, is the first ash-falling chamber below gasification furnace grate, and the first ash-falling chamber arranges air door or drawer type ash bin, vaporizer side and/or arrange enclosed furnace door above; The bottom of combustion chamber is combustion furnace grate, is the second ash-falling chamber below combustion furnace grate, and the second ash-falling chamber arranges air door or drawer type ash bin, and top, combustion chamber sets out mouth, sits pot mouth and bell.

Further, described combustion chamber comprises lower combustion chamber and upper combustion chamber, and vaporizer is communicated with bocca with the bottom of lower combustion chamber, and the bottom of lower combustion chamber is combustion furnace grate, and the top of upper combustion chamber sets out mouth, sits pot mouth and bell.

Further, the top of lower combustion chamber has closing-in structure.

Further, arrange the annular air distribution circle being communicated with body of heater outside on the top of lower combustion chamber, the inner side of annular air distribution circle arranges some wind distributing holes.

The utility model has the advantage of:

1, it comprises the vaporizer and combustion chamber that are set up in parallel, and vaporizer is communicated with bocca with the bottom of combustion chamber; Disposablely can fill up biomass fuel in vaporizer, produce fuel gas and flame under high temperature state, fuel gas and flame enter combustion chamber by bocca and are fully burned.

2, vaporizer and bottom, combustion chamber all arrange fire grate and independently ash-falling chamber, can realize independent air distribution, adjust wind supply quantity respectively as required, and air distribution is reasonable, is conducive to Thorough combustion, smoke emissioning pollution is little.

3, further, described combustion chamber comprises lower combustion chamber and upper combustion chamber, and the top of lower combustion chamber has closing-in structure, is conducive to making the flame entering upper combustion chamber from lower combustion chamber to form rotary burned flame and directly burns the bottom of a pan be sitting in pot mouth.

4, further, arrange annular air distribution circle on the top of lower combustion chamber, the fuel gas making to enter upper combustion chamber can Thorough combustion, improves the thermal efficiency.
