Biomass screw feeder and coal feeding machine: QGS4-A and QGS10-A parameters
The new biomass screw feeder and coal feeding machine are key equipment of the boiler feeding system; they can distribute fuel evenly, avoid fuel burn-back, control the fuel quantity, prevent incomplete fuel combustion, and ensure high production efficiency, safety and reliability of the boiler.
Structural principle of the biomass hopper
The material locking device mainly consists of a bin, an impeller, blades, a rotating shaft and a discharge outlet. When the drive mechanism drives the impeller to rotate, the lump material falling from the upper hopper enters the impeller compartments through the feed opening and is carried to the discharge outlet as the impeller rotates. The whole working process provides continuous and metered feeding and discharging. Because the fit between the impeller and the casing is fairly tight, it has a certain air tightness, so a certain pressure can be maintained in the boiler furnace during discharging.
