Introduction. Replacing some of the coal by biomass is an effective way to reduce CO 2 emissions from pulverized-coal-fired power plants and integrated coal gasification-combined cycle power plants. However, compared with coal, biomass has lower grindability in the existing roller mills 1 and a lower calorific value per weight. 2,3 …
Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
