  • Secondary Air Damper Control in Boiler

    In power plant boilers, the draft is obtained by means of fans namely Forced draft and Induced draft fan. The FD and ID fans develop enough draft to move the tremendous volume of air and gases through the flue gas ducts and stack to atmosphere maintaining a balanced draft in the furnace.

  • An overview of problems and solutions for components

    Dec 21, 2017A different variety of coal can be used in these types of boilers. In pulverized boilers, coal is reduced to a fine powder with the help of grinding mills and projected into combustion chamber with the help of hot air current. Pre-heated air from PA fan helps the coal to flow from the bowl mill to the boiler.

  • The Engineering of Boilers: Energy conservation

    Sep 25, 2010The potential for energy saving depends on the type of boiler installed and the fuel used. For a typically older model shell boiler, with a flue gas exit temperature of 260 C, an economizer could be used to reduce it to 200 C, increasing the feed water temperature by 15 C. Increase in overall thermal efficiency would be in the order of 3%.
