In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
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.
Nov 13, 2016· The initial process in coal based thermal power plant is coal handling.The Function of coal Handling Plant in thermal power plant is to receive, process, store, feed the coal bunkers consistently over entire life of the power plant. Coal is transported in thermal power station either by railways,roadways or rope ways.
