Forced draft is also used to identify the combustion process used in large boilers. When mechanical ventilation is supplied to these boilers, the heat transfer rate increases; the boiler can be reduced in size to produce the same amount of energy as natural draft.
Forced Draft Fans The Forced Draft Fan (FD Fan) is a fundamental part of most boiler systems and is the element responsible for creating draft inside of the boiler. The FD Fan provides the pressure and flow required to push air, fuel, and the resulting flue gases created from combustion through the boiler, catalysts, economizer, FGR ductwork
Oct 04, 2016· ID fan is basically mentioned here for Induced draft fan and ID fan is always located between dust collector and chimney. ID fan will take the hot flue gases from furnace via dust collector (dust separation system or Fume Extraction system) and wi
With highly driven technical excellence, we have been able to provide our clients with world class Forced Draft Fan. The offered fan is widely used in kitchen, air conditioned room for ventilation. This fan is efficient in functionality and consumes minimum power.
Forced Draft Fan: Forced Draft Fan supplies most of the Combustion air. This fan takes air from the atmosphere and blows it into the furnace through air ducts. The Air Heater heats the air before it enters the Furnace. FD fan produce the positive pressure inside the system i.e. furnace.
Every fan is unique and is manufactured keeping in mind the capacity of gas it needs to handle and system head requirement. Forced Draft fans are used to force air into the combustion chamber, where it mixes with the fuel being supplied. FD fan is used to regulate an appropriate amount of air to fuel ratio in the combustion chamber to maximize the fuel efficiency.

A Forced Draft (FD) fan is commonly employed in many fired heater / boiler applications for supplying combustion air to the combustion box of the fired heater. Normally the FD fan is part of the fired heater package supplied by the package vendor.
Forced air draft blower has an adjustable air intake. This allows the user to regulate the air intake for maximum efficiency. An unregulated air intake will cause the furnace in most instances to burn more wood then necessary because too much air is being allowed in causing much of the heat to be blown out of the chimney instead of being absorbed into the water jacket.
Forced Draft Fan (FD Fan) in Boilers. 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.

Forced draft: When air or flue gases are maintained above atmospheric pressure. 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 …
Balanced draft boilers have a forced draft fan at the boiler inlet and an induced draft fan at the system outlet. This reduces both flue gas pressure and the tendency of combustion gases to escape the furnace. Most modern boilers are balanced draft. The FD fans supply combustion air.
Boilers have forced draft (FD) fans to supply air for combustion of fuel. Any trip of major equipment in boiler causes the boiler parameters to vary widely before it stabilizes depending upon the action taken by the operator. The important factors to be understood in a trip of equipment in a boiler are mainly four, the specific cause of trip, plant response to the trip, immediate operator
