Reliability Analysis and Countermeasures on Type Selection of Boiler Induced Draft Fans

Abstract:

For the retrofit of precipitation and flue gas desulfurization (FGD) system, stalling issue of the boiler axial-flow induced draft fan (IDF) was analyzed. By testing the running characteristic parameter of IDF at the scene, and combining with its characteristic: curve, it was discovered that the actual working point of IDF nears its theory stall line, and stalling issue would appear during running. In order to make the actual working point of IDF keeping away from its theory stall line and avoid the stalling issue of IDF, KSE ( the steady implement of function ) equipment was installed at the entrance of the IDF' to changing the position of IDF theory stall line. The stalling issue of IDF was analyzed and probed, and the problem that the stall margin selection should be considered carefully in IDF retrofit and type selection was presented, which gives some useful suggestion for the similar retrofit in power plant.
