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.
For all Makes Models of Coal Feeders * Improve plant heat rate * Account for fuel use Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand system, but the actual amount fed is estimated and the accuracy can vary greatly.
Depending on speed pulverizers are classified as lowspeed, mediumspeed, and highspeed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuelfiring systems: bin system and directfiring system. Coal feeders are either the volumetric or gravimetric type.
