TVA How a Coal Plant Works
How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Gravimetric and Volumetric Coal Feed Systems for Boilers
Coal properties constantly vary due to sizing differences and the adverse impact of moisture. These affect heating value, flow characteristics and density. 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 .
