In order to figure out stall solution of induced draft fans (IDFs) in power plants, the stall reason of IDFs with guide vanes in Tongchuan Power Plant of 600MW is investigated. By comparing hot test data of IDFs, we also find that the IDFs are of low efficiency and high power consumption in addition to the stall problem. Considering the above condition of the IDFs, two reasonable approaches are proposed to prevent stall and reduce power consumption of IDFs. With the hot test of reformation results, it is found that the reformation scheme of IDFs with adjustable rotor blades is much better with higher efficiency and safer characteristics. The work in this study has great significance and also provides practicable ways for stall-preventing, energy-saving and cost-reducing of power plants.
