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 unavailableThe final rule establishes power plant emission standards for mercury, acid gases, and non-mercury metallic toxic pollutants which will result in: preventing about 90 percent of the mercury in coal burned in power plants from being emitted to the air; reducing 88 percent of acid gas emissions from power plants.
