Reason analysis of stall for variable static blade axial-flow induced draft fan;

In this paper, the stall phenomenon occurred in axial-flow wind fan after the input of desulfurization system and the treating process are introduced.

We havefound good process of repairing techniques use d in repairing the axes of blower and s ome typical aspects needed for special cares.

Application research on the anti-wear coatings of axial-flow ID fan blades for coal-fired boiler;

Discussing the causes of gear corrosive piting in axial-flow fan;

Change of the moisture of grain and power consumption ventilated by axial-flow fan

One is that how to demount the wheel and the output shaft that were too difficult to demount in the L60 vertical axial-flow fans,the other problem is to test static balance about the wheel.
