笔者参加了苏南一家火力发电厂1000MW机组锅炉的安装监检工作。在监检过程中发现并解决了锅炉安装过程中的一些问题,在此提出解决方案以供大家探讨。此台锅炉为上海锅炉厂有限公司生产的3098t/h超超临界锅炉,型号SG-3098/27.46-M539,为单炉膛塔式布置,四角切向燃烧,摆动喷嘴调温,平衡通风,全钢架悬吊结构。锅炉主钢架为6500t,分五层布置,炉顶钢架支承于第五层主钢架主梁上,大板梁顶标高为128.200m。在此台锅炉主钢架安装过程中,由于施工需要,在4根主立柱的中间安装了一台500t塔吊,且随着工程的进展,此台塔吊不断地升高,永远高于主立柱柱头平面。根据
I participated in a thermal power plant in southern Jiangsu 1000MW unit boiler installation monitoring. During the inspection process, some problems in the process of boiler installation were found and solved, and solutions were put forward for discussion. This boiler is a 3098t / h ultra-supercritical boiler manufactured by Shanghai Boiler Works Co., Ltd., model SG-3098 / 27.46-M539, with a single hearth tower arrangement, tangential firing at the corners, swinging nozzle temperature control, balanced ventilation, Suspension structure. The main steel frame of the boiler is 6500t, which is arranged in five layers. The top steel frame is supported on the main beam of the fifth main steel frame, and the top elevation of the large slab beam is 128.200m. During the installation of the main steel frame of this boiler, due to the construction needs, a 500t crane was installed in the middle of the 4 main columns, and as the project progressed, the tower crane was continuously raised higher than the main column stigma flat. according to
