SAIMO Coal Feeder for Fluidized Bed Boiler, Model: F57

Saimo F57 coal feeder is specially designed for feeding fuel or absorbent into all kinds of fluidized bed boilers applied in various industries such as power generation, chemical industry and metallurgy. The benefit of efficient use of coal is achieved from its precision feeding process involving in-motion weighing, totallization and flow rate control.

Saimo coal feeder accommodates a wide range of applications with capacity rated up to 300t/h, belt width from 500mm to 1400mm, and belt length within 38m. Extended belt length available is subject to factory approval.
