Induced Draft Fan In Thermal Power Plant

Induced draft fan id fan working and location in thermal power plant all in one.

Induced draft fan in thermal power plant. The rotor system causes the motion of the air gas and the casing. Normally it is done with the help of a forced draft fan. An induced draught fan id fan is provided to maintain a negative pressure in the furnace by sucking the products of combustion from it with a slight positive pressure at the discharge end vis à vis the bottom of the chimney stack. Induced draft id fan is used to draw the flue gases from the system generated from the combustion of fuel.

Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near. Large capacity fan units typically consist of a bladed rotating impeller enclosed in a stationary casing. Draft fans play critical role in functioning of the thermal power plant.

When air or flue ga. Fan a fan can be considered a mechanical device that moves a volume of fluid such as air gas or vapor through a pressure driven flow. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Simulation of fd fan in thermal power plant.

Fans in thermal power plants shivaji choudhury 2. Induced draft fan and forced draught blower are the main equipment of the fan system of thermal power plant. Motor power required for its working depends upon the following factors id fan capacity quantity of flue gases drawn from the system measured in m 3 hr. Fans in thermal power plants 1.
