WANG Juan. CAUSE ANALYSIS ABOUT SOMEWHAT LARGER ELECTRIC CURRET OF INDUCED DRAFT FAN FOR ONE BOILER[J]. Thermal power generation, 2006, (1): 59-60. DOI: 10.19666/j.rlfd.2006.01.018.
Somewhat larger electric current of induced draft fan for boiler no.2 in one power plant has been analysed. It has been found from inspection that the main causes leading to somewhat larger electric current of said induced draft fan are as follows; (1) Top corrosion in outlet flue duct of the activator; (2) Fallaway of guide plates in outlet of the activator; (3) Air leakagein due to wornout of the flue duct. After retrofitting
