The effect of moisture on coal has been studied for many years by Schenck Process LLC, and the resultant density changes are measured by the Gravimetric 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

Apr 08, 2019· Gravimetric feeders represent a significant improvement over volumetric feeders. They utilize a computer and a load cell that continuously records the weight of the feeder and its contents. When the user inputs a given dispensing rate, the computer automatically calculates the rate and begins releasing the ingredient into the process.

Oct 01, 2003· But gravimetric feeders also have an impact on the feed out of the coal bunkers, which in turn has a substantial effect on the efficient performance of the boiler. A volumetric feeder arrangement, which is usually in the form of a drag chain feeder, assumes a given volume of coal
Jun 19, 2018· The key difference between gravimetric and volumetric feeder is that we measure the rate of a gravimetric feeder in the unit of volume per unit time whereas we measure the rate of a volumetric feeder in the unit of weight per unit time.. Feeders are useful to handle bulk solids. There are two forms of feeders and we call them as gravimetric feeders and volumetric feeders.
