Sulfuric acid dew point corrosion in waste heat boiler tube

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.

Metallurgical Processes

SO 3 Formation. Smelting of sulphide ores results in large amounts of SO 2 being produced. Modern smelting processes use oxygen enrichment to generate off-gases containing from 15% to 80% SO 2.Unfortunately, the increase in SO 2 concentration results in higher SO 3 concentrations in the flue gases.. Higher SO 3 concentrations leads to the formation of sulphate and sulphuric acid in the ...
