Design and installation of the pithead power generation company temporary chimney

通辽霍林河坑口发电有限责任公司(以下简称"坑口发电公司")现有两台600MW汽轮发电机组,共用1根烟囱。国家工业建构筑物质量安全监督检验中心于2014年9月对砖套筒和钢平台进行了现场的相关检测检查及安全性评估鉴定,检测鉴定结果为该烟囱不符合国家现行标准规范的可靠性要求,影响整体安全。坑口发电公司计划2015年实施工期120天的烟囱防腐改造工程。为实现烟囱防腐改造期间机组能够正常运行,在该项目实施前要完成两台机组临时烟囱的设计及安装工作。本文从临时烟囱的设计、安装、工期进度及施工安全质量等几个方面进行了阐述。2015年12月18日坑口发电公司烟囱防腐改造工程结束,烟囱投入运行,2016年3月31日1号机组临时烟囱完成封闭工作。至此,1号、2号机组临时烟囱全部退出运行。

TongliaoElectric Power Generation Co. Ltd.Huolinhe existing two 600MW turbo generator sets, shared 1 chimneys.Constructing a national industrial building quality safety supervision and inspection center in September 2014 of sleeve brick and steel platform of site related inspection and safety assessment,detection and identification results for the chimney does not conform to the requirements of current national standards of reliability,affect the overall security.Pithead power company plans in 2015 the implementation of the chimney 120 days work anticorrosion renovation project.In order to achieve the normal operation of the unit during the renovation of the chimney,the design and installation of the temporary chimney of the two units should be completed before the project is implemented.In this paper,the design,installation,schedule and construction safety and quality of the temporary chimney are described in this paper.The end of December 2015 18 pithead power company chimney anticorrosion rebuilding engineering, the chimney is put into operation,2016 March 31,No.1 unit of temporary stack complete closure.So far,2,1 units of the temporary chimney all quit running.
