摘　　要：水中的溶解氧是造成热力设备腐蚀的主要原因之一,锅炉给水除氧是非常关键的环节。文章阐述膜法除氧器的技术原理和结构特点,分析了膜法除氧器的节能特点。针对热力除氧器,结合案例详细计算采用膜法除氧器进行改造的技术经济性,结果表明投资回报期约1年。Dissolved oxygen in water is one of the main reasons for the corrosion of thermal equipment and the deaeration of feed water is important for boiler operation. The technical principle and structural characteristics of membrane deaerator are described and the energy saving characteristics of membrane deaerator are analyzed. For the thermal deaerator, the technical economy of the membrane deaerator is calculated in detail with a case. The results show that the investment return period is about one year.
