Fan Applications

The GY5-51 and GY6-51 boiler induced draft and forced draft fans are suitable for the forced and induced draft systems of 2-670 t/h steam boilers in thermal power plants. They also meet the high-pressure head performance requirements of fluidized bed furnaces. This series of fans can also be used for dust removal, mine ventilation, and general ventilation systems. The forced draft fan transports air, while the induced draft fan transports flue gas or gases containing particulate matter. If the impurity concentration is less than 200 g/m³, the fan can be used continuously for more than four years. High impurity concentrations can still be used, but the service life will be shortened. The maximum operating temperature of the forced and induced draft fans must not exceed 250°C.

Fan Types

1. The induced draft fan and induced draft fan are single-suction, each with a range of 20 sizes, from 8 to 29.5.

2. When viewed from the motor end, a clockwise impeller rotation is considered a right-hand fan, denoted by "right." A counterclockwise impeller rotation is considered a left-hand fan, denoted by "left." 3. The paddle outlet position is indicated by the outlet angle of the casing.

4. The fan drive is D-type, using a flexible coupling.

5. Examples of full product names are as follows:

G5-51W18D Right 90°

Y5-51O18D Left 0°

G and Y represent the boiler ventilator and boiler induced draft fan, respectively.
