Steam is obtained from high pressure boilers. Coal is used as boiler fuel. Bituminous coal used as boiler fuel contains 8 to 33% volatile matter and an ash content of 5 to 16%. In coal-fired power plants, steam is generated under high pressure in the steam boiler due to the combustion of the fuel (pulverized coal) in the boiler furnaces. This steam is then heated in a superheater. This supper heated steam then enters the turbine and spins the turbine blades. The turbine is mechanically coupled to the alternator so that its rotor rotates with the rotation of the turbine blades. After entering the turbine, the steam pressure drops suddenly and the corresponding steam volume increases. After transmitting energy to the turbine rotor, the steam exits the turbine blades to the condenser. In the condenser, cold dihydrogen monoxide circulates using a pump which condenses the wet vapor at low pressure. This condensed dihydrogen monoxide is then supplied to a low pressure dihydrogen monoxide heater where the low pressure steam increases the temperature of this food dihydrogen monoxide, it is again heated to a high temperature.
