Management of coal combustion products from thermal power ...

But burning coal raises environmental problems, such as air emissions, which requires the introduction of specific technologies to minimize its effects. This includes dust removal, desulphurisation and denitrification. Products resulting of this equipments operation, fly ash, bottom ash and FGD gypsum, should be disposed in large landfills, if nothing was done. The aim of this study is to show ...

How Does a Coal Power Plant Work? - Bright

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.

Basic Layout And Working Of A Thermal Power

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. Live storage is a raw coal bunker in boiler house. The ...

Pollution from Thermal Power Plants. Harmful

Burning Coal in power plant produces a number of emissions like Carbon Dioxide, Sulfur Dioxide, Nitrogen Oxides, Ash and fine Particulate Matters. A brief review of these pollutants are given in this article. CO2 was thought of as a product of combustion and not as a pollutant. Kyoto protocol, effects of Green House gases and global warming issues have changed the way we look at CO2.

Thermal Power Plants: Excess Air Factor: Correct

Coal is a solid particle. In thermal power plants the coal is ground to a fine powder and then burned. This is to ensure that each coal particle comes into to contact with air so that the chemical reaction can take place. If the furnace is only provided with the theoretical air there may be a possibility that some coal particles do not get sufficient air.
