Forced Draft Fan |What is Forced Draft Fan|FD Fan ,, Forced Draft Fan [ FD Fan]: Forced Draft Fan is a type of a fan supplying pressurized air to a system In the case of a Steam Boiler Assembly, this fan is of a great importance As we know, for a Steam Boiler to generate steam, combustion must occur, be it any fuel (wood/coal/rice husk/pet coke/LDO/Furnace oil) and for combustion to exist one of its three main requirements, is the airRECOVERY BOILER AIR SYSTEMS Objectives of Air Systems, FD Fan Air Heater Air Duct Slide 6 presents the two types of fans used , Forced draft (FD) fans deliver combustion air to the furnace Induced draft (ID) fans remove the combustion gases and maintain a slightly negative draft in the furnace , recovery boiler air systems are their inflexibility once installed, and their need for frequent .Conversion of Existing Coal, have made converting existing coal-fired steam-generating boilers to natural gas firing more and , (FD) and induced draft (ID) fans and other boiler auxiliary equipment are usually adequate for firing natural gas but sometimes need to be modified or replaced entirely 22Combustion high CO, Aug 30, 2005· Every time the ID fan motor was started (which was after the fires had been started and steam pressure established using the FD fans only) and brought to speed, it tripped (or was tripped after reaching a time limit) out on (very) high ampsBDI EJs in Coal Plant applications, Key elements of coal-fired power station Flue Gas Desulphurization (FGD - for SO2 removal) Chimney Bypass duct , (ID) fan Forced Draft (FD) fan INPUT ANTI-POLLUTION SYSTEMS High-pressure turbine FLUE GAS OUTPUT Electricity COAL AIR , BDI EJs in Coal Plant applications ,.
