摘要: 针对哈锅自主研发的1 065 t/h(HG-1065/17.5-LMG)双布风板不带外置床的单炉膛CFB锅炉下二次风口的磨损问题,通过对CFB锅炉下二次风口设计结构、磨损机理及磨损问题进行分析,在实际改造过程中尝试了不同的解决方法,最终通过在锅炉下二次风口加装防磨帽檐,解决了CFB锅炉由于下二次风口磨损导致频繁爆管、安全运行周期短的问题。

Abstract: Regarding the problem of secondary air gate wearing in 1 065-t/h CFB boilers with no external fluidized bed heat exchanger (HG-1065/17.5-LMG, single firepot and double air distribution plates) which is independently designed and implemented by Harbin Boiler Company Limited, different measures have been tried in practice through the analysis of the air gate structure and the wearing mechanism. Eventually by installing wear-proof devices at the secondary air gates, we are able to address the wearing problem effectively, which may cause the boiler tube rupture and affect the boiler’s safe long-term operation.

Key words: CFB boiler, secondary air gate, wearing
