The form and operating requirements of centrifugal Fan for Boiler

Mar 09, 2019

In the process of operation, the centrifugal fan of the boiler is very suitable for the supply and draw air system of the steam boiler in the power plant, and also meets the requirements of the performance parameters of the high pressure head of the fluidized bed furnace, which is suitable for the supply and draft air system of the steam boiler in the thermal power plant. The performance parameters of the high pressure head of the fluidized bed furnace are also satisfied. Boiler centrifugal fans can also be used in dust, mine ventilation and general ventilation systems to a certain extent.

Requirements for the centrifugal fan of the boiler

The centrifugal fan conveys the air, and the centrifugal fan conveys the gas concentration less than 200 mg / m3. The flue gas or the impurity particles are transported by the centrifugal fan. The service life will be shortened as a result of an impurity-containing conference. The maximum operating temperature of centrifugal fan shall not exceed 250 ℃.

Forms of centrifugal fans for boilers

Boiler fan can be made into left-handed or right-handed two types. Face-to-face from one end of the motor, the impeller rotates clockwise is called the right-hand fan, expressed as "right", on the contrary, called the left-hand fan, as "left". The outlet position of the centrifugal fan is indicated by the outlet angle of the case.

 

Centrifugal fan bearing box temperature operation, the temperature is generally 60 to 75 degrees. Suggest to fan impeller to do secondary dynamic balance, fan amplitude is small, bearing temperature down. Bearing box: also known as a hinge box, is a box part for supporting and lubricating the bearing. At the same time, the axial and radial forces generated by the equipment during operation are borne. In a device with a rotating shaft, the shaft is generally supported by a bearing, and the bearing is mounted in a bearing housing, the bearing housing is filled with lubricating oil, and during operation, the bearing is used for lubrication.www.jnblower.com
