Induced Draft Fans are used as High Pressure, Medium Pressure at Low Blowers/Fans. Which generate • Low Volume of air at High pressure • Medium Volume and Low Pressure • High Volume at very Low Pressure.
Induced Draft fans are used in a system to draw flue gases from the combustion chamber and through the rest of the boiler assembly (Air Pre-heater, Dust Collectors, ESPs etc.) to the stack. Flow depends upon the amount of flue gases need to be drawn and head required to draw flue gases from the system depends upon the sum of pressure drops of all equipment installed in the path of the fan.
A boiler or steam generator is a device used to create steam by applying heat energy to water. The induced draft fan works in conjunction with the forced draft fan allowing the furnace pressure to be maintained slightly below atmospheric.
Boiler fan is the main power consumption device in thermal power units and the induced draft fan accounted for the largest proportion. Reducing the energy consumption rate of induced draft fan is the main path to reduce the power consumption rate of thermal power units.
Jan 15, 2019 · A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface.

types of draft fans used on boilers are forced -draft and induced-draft fans. They are damper controlled and usually are driven by an electric motor. The forced draft fan forces air through the fuel bed, or fuel oil burner, and into the furnace to supply air for combustion. The induced draft fan draws gases through the
Draft inducers are special fans that are installed in the flue vent connector (or sometimes in the chimney) used to vent a heating boiler or furnace. Most often we see these installed on oil-fired systems at which the technician was unable to obtain sufficient natural draft for proper oil burner operation.
Induced Draft Fan. Induced draft fan is normally located at the outlet between dust collector and chimney. The fan takes hot flue gases from the boiler through dust collector and delivers it to the chimney into the open atmosphere. ID fan creates negative pressure or suction to discharge the gases out after combustion from the furnace.
Induced draft fan is an important part of solid fuel boilers such as coal-fired boilers. Their main function is to prevent high temperature smoke, because the resistance of the boiler is stagnant in the boiler. The pressure difference is produced by gravitation, the solid fuel combustion tail gas emissions.
A draft inducer is a fan that’s located inside of your furnace near the heat exchanger. When your furnace begins a heating cycle, the draft inducer is one of the first devices that turns on. In fact, the draft inducer starts up 30-60 seconds before the burners are lit and continues to run throughout each heating cycle.
Normally it is done with the help of a forced draft fan. Induced draft: When air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric pressure. In this case, the system is said to operate under induced draft. The stacks (or chimneys) provide sufficient natural draft to meet the low draft loss needs.
Jul 30, 2019 · 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 air. And this requirement is compensated by a Forced Draft Fan.
Balanced draft boilers use induced draft (ID) fans and/or their inlet dampers to control boiler furnace pressure. The typical control system has one controller that compares the difference between
