Gravimetric and Volumetric Coal Feed Systems for Boilers

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 coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.

Feeder Conversions Schenck Process

Unlike the mechanical gravimetric feeder which acts to vary the height of coal in response to density changes to maintain a pre-established weight of coal on the weigh span, the electronic weighing feeder measures the actual density of coal and varies the belt speed to match actual with demanded combustion control delivery requirements.

Basics of Gravimetric and Volumetric Feeding : Plastics

A loss-in-weight feeder is a gravimetric feeder that directly measures the material's weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.
