Abstract: Taking account of the severe energy waste from the induced draft fan (IDF) in the large ultra-supercritical power generating unit, the retrofit scheme with frequency conversion technology is adopted. It is evaluated as the better solution to upgrade the automation level of IDF and improve the starting performance of electric motors. Moreover, the working principle of the frequency converter is presented. The practice results show that after the retrofit, the house service rate is significantly improved. Thus, the purposes of energy conservation and emissions reduction as well as anti-mechanical wearing are realized.

Key words: induced draft fan, frequency conversion, energy conservation and emissions reduction
