A coalfired power plant converts the stored chemical energy in the coal to thermal energy by burning it. That thermal energy produces steam which spins turbines (turning it into kinetic energy) for giant generators. These generators produce the electricity we use. Coal to Electricity Process The first step is unloading the coal from the train.

For better efficiency and lower separation cost to obtain the fine particles, fly ash from each electrostatic precipitator at the coalfired power plant should be collected separately. Air classification can obtain the finest fly ash, maintain its spherical shape, and consume less energy than milling.

Coal has been an important energy source worldwide; however, it is the largest source of nitrogen oxide (NOx) emissions because the amount of nitrogen in coal is larger than that of other fossil fuels. Precise control of NOx emissions is required in operations of coalfired power plants from the viewpoint of air pollution control. Although theoretical analyses of NOx generation from a coal ...

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.

Most of the coal burned in US power plants is bituminous or subbituminous coal. A fifth type, called metallurgical (or "coking") coal, is used for steelmaking. All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur content is determined by the conditions under which the coal is formed.

The mixture of pulverised coal and hot air is blown into the furnace through the front and rear walls of the boiler via 36 fuel injection ports, or burners. Here it ignites to create a fireball. Two forced draught fans supply atmospheric air, pre heated in air heaters to approximately 250oC, as combustion air to the boiler.
