Coal Feeder Volumetric To Gravimetric Conversion

Coal Feeder Volumetric To Gravimetric Conversion. Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand system, but the actual amount fed is estimated and the accuracy can vary greatly.

Difference Between Gravimetric and Volumetric

2018-6-19  There are two forms of feeders; gravimetric feeders and volumetric feeders. The 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. Reference: 1. “Basics of Gravimetric and Volumetric

Which is better: a volumetric or gravimetric weigh belt

That means the ongoing weighing and self-checking of a gravimetric weigh belt solution feeder is a better fit in this case. Alternatively, a coal handling operation may just require a constant flow of coal to be cleaned, meaning a volumetric weigh belt feeder works better for this application.
