説明

Using the crucible method,laboratory corrosion test on refractories was conducted in a simulated incinerator ash under dry or wet 1.86%HCl gas at1000℃. In the case of corrosion test in ash,glass phase of Na-K-Si-O system was formed in the sample surface,and the mass of sample increased after corrosion test. Basic oxides included in the ash and the refractories changed the chloride under HCl gas.Since the formed chloride volatilized,the glass formation was inhibited.When there was no ash,the basic oxides included in grain boundary of the refractories volatilized,and embrittlement was generated.
