doi:10.11894/1005-829x.2010.30（4).17

Abstract

Abstract:

The existence of dissolved oxygen in boiler feedwater is an important cause for the corrosion of thermal equipments，therefore appropriate chemical oxygen scavenger should be choosen to reduce the content of dissolved oxygen as low as possible. Chemical oxygen scavenger include inorganic oxygen scavenger and organic oxygen scavenger. The oxygen removal effect， corrosion inhibition capacity， advantages and disadvantages and applications instances of various chemical oxygen scavenger which presently have been studied quite often and applied widely， are summarized and compared.

Key words: feedwater deaeration, inorganic oxygen scavenger, organic oxygen scavenger

摘要：

锅炉给水中溶解氧的存在是造成热力设备腐蚀的重要原因，必须选择合适的化学除氧剂，尽可能地降低溶解氧含量。化学除氧剂分为无机除氧剂和有机除氧剂，作者对研究应用较多的几种化学除氧剂的除氧效果、缓蚀性能、优缺点和应用情况进行了综述和比较。
