The accident appraisal for cracks and hydrochloric acid corrosion of the single tube concrete chimney height 80m at a power plant is introduced.
因83年烟囱设计规范的温度应力设计安全度偏低,加上使用早强水泥及养护不足,导致该烟囱中上部筒壁出现过大的纵向裂缝和环向裂缝,以致焚烧垃圾时产生的HCl,SO2,NOX等有害气体通过这些裂缝渗入到混凝土之中,使其顶部10m范围筒壁遭受盐酸冷凝液等酸介质的严重侵蚀;还分析了腐蚀机理及危害性;证实盐酸腐蚀亦既有酸化腐蚀的特点,又有氯化物腐蚀的特征。
