Feed worm is set with the fuel distributor coaxial line, and the end of the feed worm is provided with drive link, the fuel point
Cloth device is cylindrical shape, and the outer surface of the cylinder is provided with spiral discharging passage, the biology under the promotion of the feed worm
Matter dyestuff is uniformly scattered in inside the bags by the spiral discharging passage, is provided with the sidewall of combustion chamber
For the flame point for the biomass fuel that ignites, the flame point enters in the combustion chamber through the sidewall of combustion chamber
Portion, the quantity of the flame point is multiple and is evenly spaced on the sidewall of combustion chamber, is also opened up on the sidewall of combustion chamber
There is the air-flow sprocket hole for conveying thermal current.
Further, the drive link is connected with motor by belt transmissioning mode.
Further, the spiral discharging passage by close to away from the fuel distributor central axial direction width it
Between narrow.
Further, air inlet is offered on the sidewall of combustion chamber.
Further, the external ventilation duct of the air inlet, the ventilation duct is circumscribed with air blower.
Further, the bottom of the sidewall of combustion chamber be provided be easy to itself and boiler protection shell being fixed on it is integral
Fixed mount.
A kind of biomass boiler combustion chamber of the utility model, compared with prior art with advantages below：
By being cylindrical shape by the fuel distributor designs in the biomass boiler combustion chamber, spiral shell is designed in its outer surface
Passage is revolved, the design is engaged the entrance that biomass fuel can the be made uniform and careful helical duct with feed worm, it
Whole combustion chamber is uniformly scattered in afterwards, and these biomass fuels are carried out by multiple equally distributed flame points to light behaviour
Make, the design can further lift the abundant burning degree of the biomass fuel, and then improve the combustion chamber to biomass fuel
The efficiency of combustion of material, the design is also substantially improved the utilization rate of biomass fuel.Because biomass fuel is able to fully burn
So such as carbon monoxide, the growing amount of sulfur dioxide toxic gas can be reduced further.
