Boiler Secondary Air Ventilation Fan Double Suction Large Air Volume 135kw

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.

It is applicable for exhausting gas containing dust, wooden scraps, fine and crushed fiber etc. (If there are hard particles in gas, a dust-collecting device should be installed in front of the fan). It can also be used as the common ventilation and air-exchange purposes.
1. Air purification and industrial waste gas treatment, Air filtration system, Flue gas desulfurization, Flue gas denitrification.
2. Boiler's air supply and exhaust (Coal-fired boiler, Biomass boiler, Garbage incinerator, CFB boiler, Stokerfeed boiler.).
3. Industrial boiler blowing air, Industrial boiler inducing air, Industrial boiler primary air, Industrial boiler secondary air.
4. Industrial boiler waste gas desulfurization, Industrial boiler flue gas denitrification.

1. High strength wear-resistant impeller anti-leaking bearing box.
2. Transmission part group consists of main shaft, bearing box, rolling bearing, pulley or coupling, etc.
3. Inlet and outlet flexible joints, dampers.
4. Inlet valve, bearing temperature and vibration dective sensers, impeller cleaning nozzle are optional.
5. With single suction, backward of monoblock type blades impeller have good aerodynamic performance and reliability of smooth operation.
