由于各国锅炉标准不尽相同以及设计、施工过程中的人为因素 ,引进电站蒸汽锅炉也可能发生错用钢材 ,降低接头使用寿命的材料问题。结合引进芬兰的循环流化床锅炉示范电站工程出现的材料问题 ,总结了可能发生的材料及焊接事故的几种可能性 ,并提出预防和解决的办法 Due to the different boiler standards in different countries and the human factors in the process of design and construction, the introduction of steam boilers in power stations may also cause the problem of materials misuse, reducing the service life of joints. In combination with the material problems arising from the introduction of the circulating fluidized bed boiler demonstration power plant project in Finland, several possibilities of possible material and welding accidents are summarized and measures for prevention and solution are put forward
