Coal power: Pollution, politics, and profits | Vision of Earth
The more efficient a thermal power plant is, the less thermal pollution needs to be rejected into the environment to produce the same amount of electricity. The use of cooling ponds and cooling towers reduces the quantity of heat exhausted into the living environment.
Basic Layout and Working of a Thermal Power Plant ...
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 which is used when coal supply is unavailable.
