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 ...

Coal impacts: water pollution. When you burn charcoal in your grill at home, ash is leftover. The same is true for coalfired power plants, which produce more than 100 million tons of coal ash every year. More than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.

Coal is the main source of electricity generation in fossil fuel based power plants. The use of coal in coalfired power plant (CFPP) causes raise in global temperature due to greenhouse gases emission responsible for global warming across the globe [1, 2]. It also has an adverse impact on the health of human being.

Coalfired plants are the most widely used power plant today. They involve the combustion of coal producing high pressure (typically psig, ~165240 bar) and high temperature (>500ºC) steam which is used to drive a turbine at synchronous speed (3000 rpm in countries such as the UK with a 50 Hz supply frequency, 3600 rpm in ...

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. Here's a real ...

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.
