烟气脱硫系统的腐蚀与防腐

Corrosion of Flue Gas Desulfurization System and its Prevention

介绍了燃煤电厂烟气脱硫系统腐蚀的主要部位、产生腐蚀的原因及主要的防腐措施。防腐措施包括：用合金材料、玻璃纤维及增强热固性树脂材料制造设备；用橡胶、陶瓷等材料作村里；控制烟气温度在露点以上等。

This paper involves the corrosion problem of the desulfurization system of flue gasfrom coal-burning power plant, including the major positions and causes of corrosion and princi-pal anticorrosive measures, such as the use of equipment made of alloy materisal, fibre glass andenhanced thermofixation resin, lined with rubber and ceramics, and maintaining the temperatureof flue gas over its dew point, etc.
