Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.

The Telangana superthermal power project (STPP) is a 4GW thermal power project located near the village of Ramagundam, Karimnagar district, Telangana. The project is being developed in two phases, with the underconstruction first phase comprising (2x800MW) coalbased power plant with super critical technology.
Modern coal fired central generating plant (power stations) make use of a system called Pulverised Fuel [PF] (coal) firing system. The pulverised (comminution) process is carried out on an ondemand basis by devices called pulverisers (or mills). Despite current environmental concerns, coal remains an abundant and low cost fuel for power ...
Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
