Abstract
The present invention provides a biomass direct-fired boiler feeding device that can solve the problems of biomass direct-fired power generation feeding system such as roofing, bridging, blockage, and uneven feeding; in order to solve the above-mentioned technical problems, the technology adopted in the present invention The scheme is: the end surface of the screw blade of the feeder far away from the discharge port of the feeder is involute shape; Horizontal rollers and horizontal vertical rollers, the horizontal horizontal rollers are located at the lower part of the warehouse body, and a plurality of horizontal horizontal rollers are evenly distributed, the horizontal vertical rollers are located at the upper part of the warehouse body; the feeder screw The end of the blade far away from the discharge hopper is equipped with a feeder bearing seat, the flame sensor is located between the inspection port and the discharge hopper, and a pneumatic valve is arranged at the bottom of the discharge hopper, and the pneumatic valve is fixedly connected There is a plugboard; the invention is widely used in the technical field of fuel feeding systems for biomass power generation.
Description
technical field [0001] The invention belongs to the technical field of biomass power generation fuel feeding system. Background technique [0002] Due to the characteristics of poor fluidity of biomass fuel, light specific gravity, large volume, uneven particles, flammability, and low energy density; solved problem. The main manifestations are: the material in the front silo is bridged, and the screw runs idly; the feeding screw in front of the furnace is blocked, and the fuel is blocked; Blockage; uneven distribution of fuel at the feed port in front of the furnace, tempering at the drop pipe, etc. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a biomass direct-fired boiler feeding device that can solve the problems of the biomass direct-fired power generation feeding system, such as overfill, bridging, blockage, and uneven feeding. [0004] In order to solve the above-mentioned technical prob...
