gravimetric coal feeder system

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

Gravimetric Coal Feeder ASME

The first Stock gravimetric feeder operated from 1957 to 1992, to be replaced by current gravimetric microprocessor-controlled design. This feeder was donated to Stock Equipment, refitted, and refurbished for public display in the engineering plant. Drawing from patent documents for Gravimetric Coal Feeder.

The gravimetric feeder weighs material on a length of belt between two fixed rollers using a weighing roller suspend- ed from load cells. Belt speed is determined by a tachometer attached to the motor shaft. �� microprocessor multiplies the speed and weight signal to

Should coal-fired power plants use gravimetric feeders?

In light of this reality, gravimetric weigh feeders are the better option. These instruments calculate a substance’s total weight, using that value to determine how much coal to feed. Substituting a gravimetric feeder with a volumetric equivalent isn’t feasible for power plants.
