Abstract

The No.3 and No.4 unit in Huaneng Shantou Haimen Power Production Co.

Ltd. adopts the small turbine driving technology for induced draft fan

which is the first time in domestic and has gained good energy saving effect and economic benefits. This article introduces the technical scheme of whole process automatic control for steam driven induced draft fan and the implementation results. By optimizing the preset value of guide vane opening and the test of guide vane preset excess value under special working condition

the automatic safe start and stop of the induced fan and safe and economical operation under various load conditions are realized.The study can provide references for research and development of the whole process automatic control technology for induced draft fan driven by small turbine.
