THERMAL POWER STATIONS Introduction Thermal energy is the major source of power generation in India. More than 60% of electric power is produced by steam plants in India. India has large deposit of coal (about 170 billion tonnes), 5th largest in world. Indian coals are classified as A-G grade coals.

electricity produced in India depends on Thermal Power Plants. So, the quality of coal is major consideration for the performance of Thermal Plant. Poor quality coal may not only result in poor efficiency but can also effect the life of Power Plant. Major parameters for the analysis of coal are moisture, volatile matter, ash and fixed carbon.

HFO = heavy fuel oil, MW = megawatt, TPS = thermal power station. a Efficiency is 40.87% for a coal blend of 80% sub-bituminous and 20% lignite, and 41.5% for bituminous.
