Abstract: The operation parameters and the economical efficiency of the draft fans for boilers of five power plants (five units) were analyzed, and the energy consumption rate of the fans under different conditions was obtained. According to analysis on the fan efficiency, the resistance characteristics of the fan pipeline and the adjustment mode of the fans, the basic reason of higher energy consumption of the fans in practical operation was found, and the main reformation way of the fans for the five power plants (5units) was put forward.

Key words: draft fan for boiler, economic efficiency, energy conservation, reformation
