工业蒸汽锅炉房的给水除氧,一般都采用装设大气式热力除氧器。对于热水采暖锅炉房,由于没有蒸汽来源,热网水的除氧就发生了困难。因此有些单位的热网补给水仅采用离子交换法除去水中的硬度。但是,由 The oxygen removal of the feed water in an industrial steam boiler room is generally equipped with an atmospheric thermal deaerator. For a hot water heating boiler room, there is no difficulty in removing oxygen from the hot water because there is no source of steam. Therefore, some units of hot grid make-up water use only ion exchange to remove the hardness of the water. However, by
