摘要
电厂湿法脱硫后,烟囱内部的腐蚀状况非常恶劣。本文介绍了脱硫后烟气的腐蚀性,并介绍了适合钢筋混凝土烟囱改造的四种防腐内衬材料,即发泡耐酸玻璃砖、VEGF玻璃鳞片胶泥、SL300特种耐酸胶泥和防腐涂料。对这四种材料的优缺点、使用方法、实际应用状况等分别进行了介绍,并对多种烟囱防腐蚀措施的经济性进行了比较。
Serious corrosion often happened after the desulfurization of the flue-gas in the power plant. This article introduced the anti-corrosion materials used for the flue-gas desulfurization stack, such as foam glass tile, VEGF Glass flake clay, SL300 special acid-resistant clay, and heavy-duty coating. The merits and the disadvantages, the usages, and the practical application of these materials were introduced, and the cost performances of the different materials were compared.
