摘要：
A combined finned tube anti-corrosion heat exchange device utilizing condensation heat of flue-gas belongs to the technical field of condensation heat transfer and metal anticorrosion. In view of the features that the corrosion of condensation heat exchanger mainly is electrochemical corrosion, large area of fins and more plating material consumed, and according to the principle of catholic protection and enhanced heat exchange, optimized combination of material and surface protection is actualized, the device consists of three types of combined anti-corrosion heat exchange devices. The first type includes an amorphous nickel copper phosphorus composite layer plated on a red copper finned base pipe, the fins are copper or aluminum alloy fins, and then an organic coating is applied as a whole. The second type to the device includes an amorphous nickel copper phosphorus composite layer plated on a brass finned base pipe, the fins are aluminum alloy fins, and then are applied with an organic coating as a whole.
