Detailed explanation-1: -PRAKASH Portal is developed by NTPC and sources data from different stakeholders such as Central Electricity Authority (CEA), Centre for Railway Information System (CRIS) and coal companies.
Detailed explanation-2: -What is PRAKASH portal? The Portal aims at bringing better coordination for coal supplies among all stakeholders viz – Ministry of Power, Ministry of Coal, Coal India, Railways and power utilities. This is an important step in ensuring adequate availability and optimum utilization of coal at thermal power plants.
Detailed explanation-3: -In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
Detailed explanation-4: -Lignite is used in thermal power stations since it is of lower grade and contains less percentage of carbon.
Detailed explanation-5: -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.
