2010-9-8B. Burning Process In modem systems of cement manufacture, the retention time of the material in the kiln is 30 to 40 minutes, of which the major part is in the burning zone. The temperature of the material increases rapidly from 850C to 1250C to 1300C, at which temperature clinker melt is formed. In the burning

Pollutant Formation and Emissions from Cement Kiln

2019-12-12The thermal decomposition of a solid recovered fuel SRF has been studied by two techniques. First, laboratory-scale experiments were performed in a horizontal furnace in which different atmospheres were studied to analyze the dioxins and furans PCDDFs evolved from the decomposition of the material. Sulfur presence was revealed to be important in PCDDFs formation.
