内容简介

Using the crucible method, the corrosion of refractories was tested in the lab with a simulated incinerator ash under dry or wet 1.86 percent HCl gas at 1000 deg C. In the corrosion test in ash, a glass phase of Na-K-Si-O composition formed on the surface of samples, and the mass of samples was higher after test. Basic oxides included in the ash and the refractories changed to chloride when exposed to HCl gas. But because the formed chloride volatilized, the glass formation was inhibited. When there was no ash, the basic oxides present in the refractory grain boundaries were easily volatilized, and embrittlement occurred.
