火电机组洁净化安装管理是指通过对安装设备及材料的运输和贮存、安装环境、安装工艺、检查和检验以及成品保护等环节的洁净化控制,消除影响设备及系统运行的杂质和污染物,确保设备和系统安全运行。特别是锅炉汽水系统、汽机油系统、凝结水和除氧给水系统、发电机冷却系统、四大管道、发电机、变压器、油浸式电抗器、SF6断路器、GIS装置、电气仪控盘柜、取样和取源管道等设备,国电集团在火电机组洁净化安装管理规定提出明确要求。本文以点带面,重点从锅炉联箱和受热面异物进行讨论。
Thermal power unit clean installation and management refers to the installation of equipment and materials through the transport and storage, installation environment, installation process, inspection and inspection and product protection and other links of clean control, eliminate the impact of equipment and system operation of impurities and pollutants, Ensure that equipment and systems operate safely. In particular, the boiler and steam system, steam engine oil system, condensate and deaeration water supply system, generator cooling system, four pipes, generators, transformers, oil immersed reactors, SF6 circuit breakers, GIS devices, Sampling and take the source pipeline and other equipment, Guodian put forward clear requirements on the clean installation and management of thermal power units. In this paper, the point with the surface, focusing on the boiler header and heated foreign matter discussion.
