Coal handling plant in a thermal power generating station

Thermal power plants convert heat into power in the form of electricity The heat is generated from a diverse range of sources including coal natural gas uranium solar energy and geothermal energy The heat rate HR kJkWh of a power plant is the amount of heat input required kJh to produce one unit of electricity kW see Equation 1 Oct 07 2008 A major waste in a pulverized coal fired power plant is the reject produced from pulverizing mills When coal is ground in a bowl mill heavy mineral matters are separated but they still contain a small amount of coal mixed However the heating value of the rejects is generally too low for combustion in conventional boilers
