Problems solved by technology
The current biomass boilers are prone to backfire during the combustion process when burning biomass fuel. The flame will burn the fuel in the lower hopper. safe operation and economic benefits
[0003] In addition, when the biomass boiler is working normally, the furnace is under negative pressure combustion, and the cold air from the outside can easily enter the furnace through the lower hopper, causing the oxygen content in the furnace to be too high, increasing the exhaust smoke loss and the power consumption of the induced draft fan, reducing the Boiler operating economy

The invention discloses a biomass boiler discharging hopper. The biomass boiler discharging hopper comprises a discharging hopper body, a material pushing bin, a material pushing device and a hydraulic cylinder, wherein the material pushing bin, the material pushing device and the hydraulic cylinder are arranged on the bottom of the discharging hopper body, a fixed block is fixed to the position,close to the inclined hopper wall, of one side face of the discharging hopper body, the fixed block is hinged to an air cylinder, the end of an air cylinder piston rod is hinged to one end of a connecting rod, the air cylinder is parallel to the side face of the discharging hopper body, the other end of the connecting rod is fixed to one end of a shaft, the other end of the shaft perpendicularly penetrates the two sides of the discharging hopper body through bearing pedestals, the bearing pedestals are fixed to the two sides of the discharging hopper body through supporting blocks and away from the inclined hopper wall, and one side edge of a valve in the discharging hopper body is fixed to the shaft in the axial direction. According to the technical scheme, the hopper is simple in structure, low in cost and capable of effectively preventing boiler tempering and adjusting the content of oxygen in a boiler.
Description
technical field [0001] The invention belongs to the field of biomass boilers, and in particular relates to a lower hopper of a biomass boiler. Background technique [0002] In the prior art, the biomass boiler is equipped with a lower hopper connected to the inside and outside of the furnace, and its function is to accept biomass fuel and make it smoothly enter the furnace for full combustion. The current biomass boilers are prone to backfire during the combustion process when burning biomass fuel. The flame will burn the fuel in the lower hopper. safe operation and economic benefits. [0003] In addition, when the biomass boiler is working normally, the furnace is under negative pressure combustion, and the cold air from the outside can easily enter the furnace through the lower hopper, causing the oxygen content in the furnace to be too high, increasing the exhaust smoke loss and the power consumption of the induced draft fan, reducing the economical boiler operation. ...
