Experiment on Screw Feeder at the Inlet of a Downer
螺杆式固体物料输送装置应用于下行床入口的小型实验

Delivery of catalyst particles by a screw feeder at the inlet of a downer in a hot model was studied, and the effects of pressure difference, downward wind, temperature on feeding rate were investigated. Experimentalresults show that the feeding rate can be flexibly controlled by adjusting the pressure in the catalyst feeding tank.
