【 摘 要 】

The study deals with the possibility of utilization of fly ashes from coal combustion in refractory materials and its influence on resulting properties of the material. The effect of bed and filter ash addition on the properties of the droplet and the resulting mechanical properties, bulk density, shrinkage and firing temperature of stove fireclay. The subject of this study is also reduction of SO2 emissions evolved burning of fireclay containing fluid ash rich of anhydrite. Emissions of SO2 were observed by TG-DTA method. Characterization of prepared samples and study of heat treatment processes were based on XRD and TG-DTA.
