Boiler in a power plant has two functions The Combustion system converts energy in coal to Heat Water and steam system converts the heat to steam at high pressures and temperatur
Coal bottom ash and boiler slag are the coarse, granular, incombustible by-products that are collected from the bottom of furnaces that burn coal for the generation of steam, the production of electric power,
The calorific value of power plant coal is the amount of potential energy in coal that can be converted into actual heating ability Calorific value of coal can be determined either by calculation from chemical analysis or by burning a sample in calorimeter
The development of a 700 °C steam power plant to operate on coal in combination with biomass will enable a reduction of CO 2 emission of around 40% compared with the most advanced USC power plants operating today
The size of the coal differ for plant to plant As in thermal power plant the pulverized coal used so the range of the coal size is in between 70 - 200 micron 242 Views
