Double feeding system of biomass fluidized-bed gasifier

A double feeding system of a biomass fluidized-bed gasifier is characterized by consisting of a first feeding device, a second feeding device and a gasifier, wherein a supporting framework is mountedand fixed to the front side of the gasifier; a first material receiving hopper and a second material receiving hopper are mounted and fixed to circular holes in a metal plate on a first cross beam respectively; a first material bin and a second material bin are mounted in circular holes in a metal plate on a second cross beam respectively; a first screw conveyor and a second screw conveyor are mounted and fixed to a metal plate on a third cross beam respectively. Through the belt conveyors, discharging barrels, the material bins, electric gate valves, the screw conveyors and star-shaped feed valve conveying pipes, the double feeding system with double identical structures is formed, and different fuels are conveyed into the gasifier for gasification to obtain new energy; meanwhile, shortage of single biomass fuel
