2019-8-12·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. Since ID fans can handle hot flue gases, they have more corrosion and erosion problems even when used with
Industrial boiler systems can cope with much higher pressures than pressure cookers. These boilers are welded from thick steel plates that are up to 35 mm thick, making pressures of 30 bar and more possible. A stable, robust design is also essential – if a boiler of this type were

But ID (Induced Draft) Fan produces induced Draft/ Negative Draft on Boiler/Furnace. In Boiler Furnace area are kept0-5 mmwc.ID takes the flue gas from furnace through different heat exchanger(Superheater,Air pre-Heater,Economiser,ESP) in chimney, finally in to the atmosphere.
Radial fans are industrial workhorses because of their high static pressures (upto 1400 mm WC) and ability to handle heavily contaminated airstreams. Because of their simple design, radial fans are well suited for high temperatures and medium blade tip speeds. Forward-curved fans are used in clean environments and operate at lower temperatures.
The fan is performing as it should as it relates to pressure rise. What I am trying to do is plot the operating point on the fan curve live with the instrumentation that I have. The true problem is we suspect the fan is surging or in a rotating stall at certain operating points because the ductwork and structural steel is vibrating severely.
Jun 18, 2019 · What others are saying Xianrun Blower ID Fans for Industrial Boilers, check www.lxrfan.com, xrblower.com, [email protected] Frequency converter is often applied for complex system, poor working conditions, high load, long running condition.
In a Steam Boiler operation assembly, Industrial Fans and Blowers are the heart of the system.They are responsible for all other subsequent operations taking place in a boiler i.e, combustion of fuels, generation of hot gases and transportation of flue gases through boiler tubes and other equipment.
How could the capacity of the ID fan be determined for a bagasse fired boiler ? I noticed on my boiler that at a certain flow rate, it is really very difficult to manitain a negative pressure in the furnace and the ID is almost at 100 %.
