Hot Corrosion Resistance of Aluminosilicate Refractories – Comparative Tests in the Secondary Combustion Chamber of a Hazardous Waste Incinerator

This paper presents the alkali and sulphur vapour corrosion resistance of aluminosilicate refractories under industrial conditions. Aluminosilicate refractory samples with Al2O3 contents ranging 42–90 mass‑% were exposed for 8 months to the corrosive atmosphere in the secondary combustion chamber (gas temperature approx. 950 °C) of a hazardous waste incineration facility.
