Abstract
|
Induced draft fan as one of the main auxiliary of the thermal power plants , and seriously affect its output because of wear and tear and frequent updates maintenance , has become one of the hidden dangers of the safe operation of the thermal power plant boiler . Induced draft fan as important auxiliary equipment for coal-fired boilers , directly affect the safe operation of the generator set , Statistics thermal power generating units of 100MW over 1991 only because of the Boiler Fan failure caused annual losses of up to 1.27 billion kW · h . Seen to improve the reliability of the plant fans running safe operation of the power plant is very necessary . # 4 furnace for Lingquan power plants cited specific issues of fan wear , in-depth analysis of the induced draft fan wear causes and propose improvement and prevention the wear of further measures , implementation and Lingquan power plant significantly improved results , and achieved satisfactory results. This article is divided into four parts , the first part is mainly described the research background and significance of the papers ; second part is mainly caused by the internal fan wear mechanism is in-depth discussion and research ; third part mainly on the basis of the analysis in the wear and tear reasons , according to the project actual needs of a variety of commonly used approach of induced draft fan wear , and its economic analysis , makes the induced draft fan wear problem of decision-making more scientific and economic ; fourth part is the full text of the summary and outlook .
