摘要：

This paper presents the sulfuric acid dew point corrosion found on waste heat boiler tube for a copper smelting furnace. Macroscopic and microscopic observation results for the failed boiler tubes are shown. Then the analyzed results by X-ray fluorescence, X-ray diffraction and EPMA on failed boiler tubes are demonstrated. Finally effective alloying elements for waste heat boiler tube material against sulfuric acid dew point corrosion are briefly described on the basis of the exposure test results for three kinds of steels in the radiation section of the waste heat boiler.
