May 31, 2017· Coal-fired power plants emit 84 of the 187 hazardous air pollutants identified by the U.S. Environmental Protection Agency. Several of these pollutants cause cancer, according to the National Toxicology Program. Hazardous air pollutants released by coal-fired power plants can cause a wide range of health effects, including heart and lung diseases.
Coal is fossilised plants: mostly formed during Carboniferous period (about 350 to 300 million years ago). Earth had dense forests of tree ferns during Carboniferous and there was vast wetland all around. Climate was tropical and humid. Inundation of forests by sea water was common. Trees did not decay under pressure and heat, when got suddenly buried in swaps. Plants eventually became ...

Also upgrading some existing coal plant system to super or ultra_super critical operation results in improvement in efficiency and hence justify the extension of the life of the plant. And of course; improving the efficiency of the coal_fired power plant will make us use less coal per unit of energy. Coal-fired power plant environmental impact:
The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary ...
