Two key factors cause problems when handling coal. First, coal sinks in water. Second, water collects in low spots. Combine this with a conveyor system, which operates below ground and has dust, fine particles and chunks falling from the belt. With nowhere to drain, water collects, and whatever is with it must be pumped up and out …

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2. Learn how the …

Thermal power plants rely heavily on coal as their primary fuel source. Coal handling involves transporting coal from mines to the plant via waterways, rail, road, ropeways or pipelines. At the plant, coal is unloaded and stored either outdoors in piles or heaps, underwater, or in live storage bunkers. Effective coal storage aims to prevent ...

How a Coal Plant Works. 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 water and returned to the boiler to start the process over.
