Industrial Boiler Exhaust Energy Efficiency Centrifugal Blower Fan
Introduction
The 5-05 series industrial centrifugal blower fan can be used in the feeding system of 2-670t/h steam boiler in thermal power plants, it can also meet the requirements of the high-pressure head performance parameters of the fluidized bed furnace.
Industrial Boiler Exhaust Energy Efficiency Centrifugal Blower Fan can be used for more than four years when the concentration of impurities is less than 200 mg/m3.
If it contains a lot of impurities, it also can be used, but it will shorten the service life.
The maximum operating temperature of the induced draft fan must not exceed 250°C.
The performance of the industrial centrifugal fan is expressed by parameters such as fan flow, full pressure, spindle speed, shaft power and efficiency.

Advantages and Features
1. industrial centrifugal blower fan Impeller:
12 pieces of backward aerofoil blades are welded between the Arc cone front plate and the flat shaped rear plate. Because of the use of airfoil blades, the fan is guaranteed to have high efficiency, low noise and high strength. The impeller is corrected by static and dynamic balance, so the operation is stable. Forced draught fan and induced draught fan of the same machine number have same impeller structure.
2. industrial centrifugal blower fan Casing:
The casing is a volute welded by ordinary steel plates.
The casing of a single suction fan is made in three different forms: The No. 8 to 12 casing is made into an integral structure and cannot be disassembled; The No. 14 to 16 casing is made into a two open structure; The No. 18~29.5 casing is made into a three open structure.
The induced draft fan and the volute plate are appropriately thickened to prevent wear.
3. industrial centrifugal blower fan Inlet:
The converging and streamlined air inlet is made into a unitary structure and bolted to the inlet side of the fan.
4. industrial centrifugal blower fan Adjustment door:
A device for regulating the flow of the fan, axially mounted in front of the air inlet. The adjustment range is from 0° (full open) to 90°(fully closed).
