Gravimetric Coal Feeder - American Society of Mechanical EngineersA variety of mechanical feeders, including drag-chain conveyors and rotary pocket feeders, historically have been used to volumetrically control the flow of fuel to coal pulverizers on power generators. Most power generation in the United States has relied on burning fossil fuels in steam boilers, with coal as the fuel of choice.types of coal feeder,The STOCK® Gravimetric Feeder - The American Society of .In response, batch-type weighing scales, such as those manufactured by Stock. Equipment Company and others, were finding use in pul- verizer feed systems placed ahead of the volumetric feeders. Problems were encountered with the inherent complexity of such systems, including coal pluggage at transfer points.Volumetric and Gravimetric Feeder - GEAThere are many types of feeders available to handle bulk solids and they can be divided into two categories: volumetric and gravimetric. A volumetric feeder discharges a volume of material as a function of time while a gravimetric feeder weighs material.

When selecting a feeder, how can I determine whether volumetric or .

A volumetric feeder is a set-speed device that's dependent on a constant, choke-fed, or flooded infeed of a particulate solid, and it feeds by volume only. The feed material must also have consistent material properties, including bulk density. Volumetric feeder types include screw (helix), rotary vane, belt, vibratory, en masse.
