15-20t/h Automatic Biomass Feeder
Product introduction
The new biomass screw feeder and coal feeder are key equipment of the boiler feeding system; they can achieve uniform distribution, avoid fuel back-burning, 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 is mainly composed of a silo, an impeller, blades, a rotating shaft and a discharge port. When the driving mechanism drives the impeller to rotate, the lumpy material falling from the upper hopper enters the impeller compartment through the feed inlet and is delivered to the discharge port by the rotation of the impeller to be discharged. The whole working process can feed and discharge materials continuously and quantitatively. Because the fit between the impeller and the casing is relatively tight, it has a certain sealing performance, which can ensure that a certain pressure is maintained in the boiler during discharging.
