Forced Draft Industrial Boiler Centrifugal Blower Fan High Air Flow
Double-suction industrial boiler fans have a large flow and are widely used in large factories. The induced draft fan adopts a double-sided short-term, double-support structure. The entire fan is composed of a rotor group, a casing, an air inlet, an air inlet box, an adjusting damper, a transmission group, a sliding bearing, a turning gear and a forced lubrication system.

Surface Processing
The surface of the fan shall be polished to remove any protuberances, welding spatters, burrs, sharp edges, scrap iron and greasy dirt before being finished with electrostatic grey 9006 epoxy coatings. The finished gloss level shall be greater than or equal to 70%. The surface shall be a level one without sags, cracks, cockles or detachment.
Nameplate
A permanently fixed aluminum nameplate shall clearly display the fan number, product model and serial number (a unique ID for each fan) so that the parts used can be traceable by customers.
Inlet
The inlet shall be designed in line with aerodynamics. It shall be streamlined for better airflow movement and efficiency, reducing turbulence and sound.
Belt Drive and Coupling Drive
The fan shaft shall be treated through hardening and tempering and finish turning processes up to the hardness level of HB250-280. Its maximum load shall be 35% more than the highest fan speed. The shaft shall be supported by two bearings with L10 rating service life of over 80000 hours. It shall be sealed and can be lubricated under normal operating temperatures. The pulley shall be of cast iron type and shall be sized for a minimum of 150% of the driving power. There shall be pulley and belt guard. Flexible coupling equipped with a guard shall be used. The factor of safety of power transmission and torsion shall meet the design requirements.
Motor
The motor shall be carefully matched to the fan load. It shall be IP54 rated with class F insulation. Ball bearing that can be lubricated shall be used. The motor and drive mechanism shall be isolated from the airstream to avoid grease or dirt accumulation.
