Problem and Solution of Frequency Conversion Transformation on Axial FGD Booster Fan in 600MW Unit

Abstract:

in 600 MW unit of a certain power company, the frequency conversion transformation on an axial FGD booster fan had been done, but it was found that have only little energy-saving effect and the investment recovery period would be very long. Based on performance characteristics test, the reason of this problem was analyzed. It shows that the transformation scheme in effect is unsuitable. The optimized scheme was proposed and suggesting good effect through energy-saving estimate. The company implemented optimization and then found the energy-saving index is almost the same as estimate. This problem is representative for frequency conversion transformation of fans, it can be avoided through performance characteristics test and energy-saving estimate before transformation.
