摘要
介绍了贵溪电厂4号炉螺旋槽管式空预器的异常情况,针对该空预器甲侧炉前管箱漏风、堵灰异常严重的情况,在空预器结构、入炉煤质、环境温度变化和锅炉烟风系统总体布置等多方面进行了原因查找和综合分析,认为是多方面因素共同作用引起的。并就减少空预器漏风、堵灰提出了建议和预防措施。
The abnormal phenomena of screw pipe air preheater in # 4 boiler of GuiXi power plant were introduced, and reason analysis were performed to the problem of serious air leakage and ash jammed in the air preheater. finally, measures on reducing air leakage and ash jamming were put up.
