Gravimetric Coal Feeder System

  • Gravimetric Feeders Deccan Mechanical and

    The major function of Gravimetric Coal Feeders is to continuously feed the specified quantity of raw coal from the overhead bunkers to the coal pulveriser. However, it is used for any solid fuel feeding to boilers.gravimetric coal feeder system energy conservation,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.
