Should coal-fired power plants use gravimetric feeders?

Substituting a gravimetric feeder with a volumetric equivalent isn’t feasible for power plants. Machinery that burns coal to produce a specific amount of energy must not receive an excess or paucity of material. If a pulveriser, for example, receives more coal than it is equipped to handle, the mechanism may break, resulting in downtime and lost productivity.

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.
