目前葡一联蒸汽锅炉房存在以下两个方面的问题,一是由于锅炉给水中溶解氧的含量超标,致使锅炉及伴热管道腐蚀严重,二是该站锅炉蒸汽回水温度较高,进入系统循环将会导致系统过热,致使锅炉房蒸汽回水水箱在冬天常发生“冒气”的现象,存在安全隐患。本文针对锅炉给水除氧及锅炉冷凝水回收存在的问题,简要介绍锅炉水处理脱氧方式的选择及蒸汽凝结水回收系统的设计,从而达到保护蒸汽锅炉及管线,提高整个热力系统的效率。 At present, there is a problem in the following two aspects of the Portuguese steam boiler house: firstly, the content of dissolved oxygen in the feed water of the boiler exceeds the standard, resulting in serious corrosion of the boiler and the tracing pipe; secondly, the backwater temperature of the boiler steam of the station is high, entering the system Cycle will lead to system overheating, resulting in the boiler room steam backwater tank often occur in winter, “gas” phenomenon, there is a security risk. This paper aims at the problems existing in the deaeration of boiler feed water and the recovery of boiler condensate water. The selection of deoxygenation mode of boiler water treatment and the design of steam condensate recovery system are briefly introduced so as to protect steam boiler and pipeline and improve the efficiency of the whole heat system.
