摘　　要：对汉川三期工程和蒲圻二期工程两个超超临界燃煤机组的锅炉补给水系统的工艺进行了比较。得出两种工艺均能满足出水水质要求,一级除盐+混床运行操作及管理相对复杂,维护量较大,且对环境有一定的污染,但经济上综合年费较低;二级反渗透+混床除盐系统占地小、安装方便、运行操作及控制相对简单,环境污染较小,但综合年费较高。Boiler feedwater system technology of two ultra - supercritical coal - fired units of Hanchuan electric power plant phase iii extension project and Puqi phase ii project were compared. Both of two technologies can satisfy the water quality requirements in electric power plant. Advantage of primary demineralization ＋ mixed bed system was low economic cost but with relatively complicated operation, management, acid -base storage measurement and measuring system. Slight environmental pollution was a disadvantage of this system. However, for two stages RO system ＋ mixed bed demineralization, compact equipment, convenient installation, simple operation and friendly to environment were excellent except relatively high management expenses.
