目前国内广泛使用的卧式快装锅壳锅炉,由于许多原因,锅壳在运行期间普遍产生鼓包,尽管有关资料及后来颁布的《在用锅炉定期检验规则》对鼓包修复有明确要求及原则规定,但实际上,在同样条件下,各部门采取的修复工艺及措施都不尽一致,多数部门处理时不考虑鼓包变形的具体情况,片面强调挖补,而忽视了经济性与合理性,甚至导致修复后的锅炉又产生不安全因素。对此,本文就一起严重缺水造成的锅壳大面积过热鼓包处理情况作一介绍,仅供参考。 1 基本情况
Currently widely used horizontal quick-loading boiler shell boilers, for many reasons, the drum shell during operation generally produce drum kits, despite the relevant information and the subsequent promulgation of the “periodic inspection rules in the boiler,” Drum repair has clear requirements and principles However, in fact, under the same conditions, the repair processes and measures taken by various departments are not consistent. Most departments deal with the situation without regard to the deformation of drum kits, and one-sidedly emphasize digging while ignoring the economy and rationality and even lead to After the repair of the boiler and insecurity. In this regard, this paper on a serious shortage of water caused by the case of large-area overheating drums made an introduction, for reference purposes only. 1 basic situation
