电厂SCR脱硝系统与石灰石-石膏湿法脱硫系统故障分析
Analysis on Faults of SCR Denitration System and Limestone-gypsum Wet Desulfuration System in Power Plant
摘要
Abstract
This paper investigates and analyzes faults of selective catalytic reduction (SCR) dcnitration system and limestonegypsum wet desulfration system of coal-fired units in one region,and uses a method combined k-means clustering and association rules based on fault data to analyze correlation between faults of systems and characteristic parameters of the unit.Results indicate that three main faults of the SCR denitration system include low temperature annealing operation,blockage and leakage,the most seriously faulted parts of the limestone-gypsum wet desulfuration system are booster fan,gas-gas heater (GGH) and absorption tower,fault of SCR denitration equipment mostly happens to the unit with low load rate,short denitration commissioning time and tangentially fired boiler,and the fault of limestone-gypsum wet desulfuration system frequently happens to the unit with coal of high sulfur content,small capacity and tangentially fired boiler.It points out that by analyzing faults of SCR denitration system and limestone-gypsum wet desulfuration system of the coal-fired unit,it is able to greatly improve economy and security of the whole unit.关键词
