For example, in normal operation, when the oil pressure of the supply fan suddenly rises to 10MPa full range, the moving blades of the supply fan cannot be adjusted, resulting in an automatic decrease in fan output, negative pressure fluctuations, and a decrease in unit load; Oil leakage in the control oil pipe of the air supply fan, causing a decrease in system oil pressure; A large amount of steam leakage occurs in the water valve of the warm valve; Leakage and other issues with the cooling water control valve of the superheater. Serious impact on the safe operation of the unit. Through summary and analysis, the root cause problem was ultimately discovered and thoroughly solved. This article mainly summarizes the analysis of abnormal causes and the sharing of experience in the handling process.","PeriodicalId":305807,"journal":{"name":"城市建设理论研究—建筑结构","volume":" 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141825708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
