NOUFERROUS METALLURGICAL EQUIPMENT

In response to the significant deviation between actual operating flue gas parameters and design parameters during the desulfurization production of a copper smelting project, which caused severe condensation and corrosion in the front-end fan and piping of the dynamic wave system, this study systematically analyzed various factors, including the desulfurization process, design data, operating parameters, and fan materials. Starting from the corrosion mechanism, and combining theoretical analysis, data evaluation, and practical investigation, the root causes of the problem were thoroughly explored, and a targeted technical modification plan was developed. The implementation of this plan effectively resolved the equipment condensation and corrosion issues, significantly improved the operational availability and production efficiency of the system, and reduced both the copper processing cost per ton and the SO₂ removal expenses.
