高压除氧器是发电厂重要的辅助设备之一。长期以来,多台并联运转的除氧器,在新厂建设时都设计了压力控制系统,但几乎都没有能投入运行,去年5月我们对四个并联的压力系统进行了改进设计,收到了明显的效果,实际运行表明,系统的改进设计是合理的,由于这四个系统投入自动控制,使全厂仪表的投运率提高了16％。一、生产流程概述除氧器是利用蒸汽将软水加热,在一定的压力下(该厂为5公斤/厘米~2)使腐蚀性气体(主要是氧)逸出。豆坝发电厂共有四台高压除氧器:1~#与2~#高压除氧器为
High-pressure deaerator is one of the important auxiliary equipment in power plant. For a long time, several deaerators operating in parallel were designed with pressure control systems in the construction of the new plant but almost none of them were put into operation. In May last year, we improved the design of four parallel pressure systems and received Obvious effects, the actual operation shows that the system is an improvement of the design is reasonable, because these four systems put into automatic control, so that the whole plant instruments operating rate increased by 16%. First, the production process Overview Deaerator is the use of steam to soft water heating, under certain pressure (the plant is 5 kg / cm ~ 2) so that corrosive gases (mainly oxygen) escaped. Douba power plant a total of four high-pressure deaerator: 1 ~ # and 2 ~ # high-pressure deaerator
