Boilers

Boiler centrifugal induced draft fans, are widely for ventilation, dust extraction, cooling of power production, factories, mines, tunnels, cooling towers, ships and buildings.  Also, they can be using in air conditioning equipment and household appliances for Cooling & ventilating. Furthermore, the Boiler centrifugal induced draft fan can be for grain drying and delivery. They are good for wind tunnel wind source, hovercraft inflation and propulsion as well.

The working principle of the boiler centrifugal induced draft fan is basically the same as that of the turbo compressor, except that the gas flow rate is low and the pressure does not change much. Normally, it is not necessary to consider the change of the specific volume of the gas, that is,  to treat the gas as an incompressible fluid. This Induced draft fans for large-scale power station boilers are generally fixed-blade or movable-blade adjustable axial fans. And, the lifting force generated by the impeller rotation is to introduce the flue gas in the boiler into the desulfurization island or chimney in the axial direction.
