Abstract：The combustion of coal powder will produce acidic gases,which will harm the environment.The desulfurization tower,as the main equipment for recovering these acidic gases,often suffers from corrosion due to its poor internal conditions.To deeply study the corrosion and protection measures of the desulfurization tower,analyze the mechanisms of chemical and physical corrosion,summarize the corrosion characteristics of the desulfurization tower's interior under different conditions,discuss the existing protection measures and their deficiencies,and propose further research methods and ideas to reduce the internal corrosion of desulfurization towers in coal-fired power plants.
