How Does a Coal Power Plant Work? - Bright Hub Engineering

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2. Learn how the process works as well as interesting ...

Forced draught: draught is obtained by forcing air into the furnace by means of a fan (FD fan) and duct-work. Air is often passed through an air heater; which, as the name suggests, heats the air going into the furnace in order to increase the overall efficiency of the boiler. Dampers are used to control the quantity of air admitted to the furnace.

Utilization of booster fans in underground mines

Dec 10, 2008· The ID fan exhausts flue gases from the furnace and induces combustion air into the furnace by having the furnace operated under negative pressure. Forced Draft (FD) fans are used for supplying the combustion air into the furnace of a boiler. A good design of fan and its control system increases plant reliability by improving furnace pressure ...

Coal-Fired Performance and Cost

Fabric filters can be categorized by several ways, such as the type of cleaning (shaking, reverse air, pulse jet), direction of flue gas flow (from inside the bag toward the outside or reversely), location of the fan (ID or forced draft, FD, fan), or size (low, medium, or high gas flow quantity).
