Gravimetric and Volumetric Coal Feed Systems for BoilersThe effect of moisture on coal has been studied for many years by Stock, and the resultant density changes are measured by the Gravimetric Feeder. The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the.rotary drum gravimetric raw coal feeder,How to Design Efficient and Reliable Feeders for Bulk Solidsfour most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the other hand, modulates the mass flow rate. This can be done either on a continuous basis (the feeder modulates the mass per unit time of material discharge) or on a batch basis (a certain mass of material is.
