摘要
随着锅炉运行时间的增长,积灰问题愈发严重,不仅增加了烟道阻力、降低了锅炉效率,还可能引发安全隐患。为此,本文深入研究电厂锅炉尾部烟道飞灰的特性,分析了其解堵原因,并探讨当前解堵技术的现状及发展趋势。本研究对于保障锅炉的安全稳定运行、提高能源利用效率具有积极意义,以期为电厂锅炉的维护管理提供有益的参考。
Tail flue,due to the poor combustion of coal quality,low smoke temperature and high ash content,is often faced with ash accumulation problems.These solid granular ash is deposited in the dense pipe row,especially on the leeward surface,which is easy to form the ash layer,which seriously affects the heat transfer efficiency of the heating surface of the tail..
