Abstract

The invention discloses a biomass combustion furnace with stable material air and few sparks. The biomass combustion furnace comprises a horizontal feeding device, a vertical feeding device, a hearth feeding pipe, an ash discharge device, a hearth, an upper hearth and various air ducts, wherein a hearth bottom of the hearth, an ash discharge gear of the ash discharge device, annular air duct air manifolds of the annular air ducts, and a vibrating screen are integrally in a circular table shaped annular shape, and the hearth bottom, the ash discharge gear and the annular air duct air manifolds and the vibrating screen are arranged from the bottom up sequentially. According to the biomass combustion furnace, the hearth bottom, the ash discharge gear, the annular air duct air manifolds and the vibrating screen that are integrally in a circular table shaped annular structure are assembled together, and a conical surface is formed at the hearth bottom, so that fuel can be dispersed towards the periphery easily and stably, and straight air pipes and bent air pipes can allow the air to be distributed in the same horizontal plane in the hearth more uniformly; and chip discharge grooves are uniformly formed in vane blade of a vertical screw, so that the sparks generated by combustion of chip-shaped objects are reduced, flue gas pressure of a flue gas emission channel is balanced, and the trends of the flames in the hearth are uniform.

Description

technical field [0001] The invention belongs to a solid fuel combustion furnace, and relates to a fully automatic feed biomass combustion furnace in which the fuel is combusted from top to bottom, in particular to a biomass combustion furnace with stable feed wind and less sparks. Background technique [0002] The combustion device that uses the top-down combustion method for fuel has been continuously developed. The existing feeding device is "closed biomass fuel feeding device", patent number: CN200820185125.6. The flap door device of the device, the flap door device is provided with a fuel inlet, the lower end of the screw device communicates with a metering silo, and the metering hopper is equipped with a fuel level detection device; another example is the applicant CN201110072163.7 of "A Fuel Feeding Device for Furnace with Full-automatic Feeding and Burner Furnace", which adopts the method of mobile replenishment and push-type feeding, and continuously promotes to real...
