CFB Boiler Single Inlet Wear Resistant Air Circulation Fan
Introduction:
This series of fans can also be used for dust removal, mine
ventilation and general ventilation systems. The blower delivers
air, and the induced draft fan delivers flue gas or gas containing
foreign particles.
The 5-06 series 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.
It 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 fan is expressed by parameters such as fan
flow, full pressure, spindle speed, shaft power and efficiency.

Advantages and Features:
1. 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. 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. Inlet:
The converging and streamlined air inlet is made into a unitary
structure and bolted to the inlet side of the fan.
4. 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).
5. Transmission parts:
The main shaft of the transmission part is made of high-quality
steel, and the 5-06 series of fans are all made of roller bearings.
The bearing housing is available in two forms: No. 8 ~ 16 uses a
whole cylindrical bearing housing; No18 ~ 29.5 uses two independent
pillow bearing boxes.
The bearing housing is equipped with a thermometer and an oil level
indicator (only the induced draft fan). The lubricating oil uses
46# mechanical oil, and the oil quantity is implemented according
to the oil level mark. When the No8-16 integral cylindrical bearing
housing uses dry oil, the oil retaining plate should be added to
the ball side of the bearing housing, and the fixing grooves
communicate with each other. The induced draft fan is equipped with
a water cooling device, so a water supply pipe must be installed.
Water consumption varies with temperature, and is generally
considered to be 0.5 to 1 m3/h.
