gravimetric coal feeder theory

System for improving fuel feed control of volumetric coal

Thus, in the case of the gravimetric feeder 28, at input line 40, a signal representing the weight (effectively, of density) of a predetermined volume of coal, is sent to the microprocessor 20; and the output line 42 furnishes a control

Gravimetric Analysis Principle with Types, Advantages and

A gravimetric feeder is a self-calibrating, speed-based dosing device based on weight. On the other hand, a volumetric feeder does this depending on the velocity of volume. Using loss-in-weight technique, which calculates the decreased weight during dosing, weight is estimated.

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.
