Abstract In-plant corrosion tests of five steels were conducted in a heating boiler in China to study the desulfurized flue gas corrosion coupled with deposits after the FGD (flue gas desulfurization) unit. The surface temperature of the steel was the key factor in the deposition and corrosion process. As the surface temperature increased, the corrosion of the steels was first exacerbated due to the increase in the Cl− concentration in the deposits and then mitigated due to the lack of the electrolyte. The stainless steels in this work showed much better performance than did the low alloy steel.

脱硫烟气腐蚀与加热锅炉沉积物

摘要 在国内某供热锅炉上对5种钢进行了厂内腐蚀试验，研究了FGD（烟气脱硫）装置后脱硫烟气腐蚀与沉积物的关系。钢的表面温度是沉积和腐蚀过程中的关键因素。随着表面温度的升高，钢的腐蚀首先由于沉积物中 Cl-浓度的增加而加剧，然后由于缺乏电解质而减轻。这项工作中的不锈钢表现出比低合金钢更好的性能。
