Jun 08, 2018· The condensed water is thus cooled down and then recirculated back through the coal-fired boiler to again turn to steam and power the turbines. This is the closed-cycle loop part of the system and it reuses the water continuously. In the other part of the water-use cycle of the plant, the open-loop cycle, massive amounts of water are taken from a …

1.1 Overview. Nearly 50% of the electricity generated in the world uses coal as the primary fuel. The function of the coal-fired thermal power plant is to convert the energy available in the coal to electricity. Coal power plants work by using several steps to convert stored energy in coal to usable electricity.

A simplified layout of a thermal power station is shown below. Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage ...

Sep 23, 2021· Coal-fired 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 the water, and returned to the boiler to start the process over.
