Transformation and application of 480 t/h CFB boiler induced fan inverter

Abstract

Abstract: The induced fan efficiency of 150MW CFB boiler in Huadian Wuda Cogeneration Plant was low, and the fan had other disadvantages such as high starting current, high rotational speed and high bearing temperature, which would lead to high auxiliary power rate. Therefore a transformation scheme was proposed that installing inverter in view of the present problems. After the transformation, the energy saving effect was significant, which improved equipment operating situation and extend equipment service life.

Key words: induced fan, inverter, energy conservation, auxiliary power ratio
