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 ...

Silos design - Flow of powder

It is important to size properly such feeder, since an undersized feeder can have bad consequences on the way the powder will flow in the hopper, and can turn a mass flow bin into a funnel flow bin. The feeder must be designed to draw out the solid on the entire section of the hopper (which can lead to some overdesign compared to what is actually required for the process).
