load calculation of coal feeder

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.

Gravimetric and Volumetric Coal Feed Systems for Boilers

feeder has drifted far out of calibration. Nowhere throughout the feeder's operating range does the measured rate equal the set rate. By adjusting the feeder's weight span setting the linearity curve is rotated so that perfect correspondence between set and measured rate can be established at any given point (e. g. 90%
