武钢热力厂HG75/39-450型工业锅炉是与一米七轧机同步建成投产的。几年来运行一直压常,但近期连续发生两次水冷壁管在燃烧运行过程中突然破裂,停炉换管。众所周知,锅炉管在运行过程中突然发生破裂,其影响因素较多,如材料的选择,制造安装、维修等多方面问题,也有因运行条件不当而引起的。而后者往往使锅炉管造 WISCO Thermal Plant HG75 / 39-450-type industrial boilers and m-7 rolling mill is completed and put into production simultaneously. Operation has been pressured in recent years, but the recent occurrence of two consecutive water-cooled tube wall during the combustion operation suddenly rupture, shutdown furnace change. As we all know, boiler tube suddenly breaks down during operation, and its influencing factors are many, such as material selection, manufacture, installation, maintenance and many other issues, but also due to improper operating conditions caused. The latter tends to make boiler tubes
