INFLUENCE OFCHARCOALON QUALITY OFAGGLOMERATE

This paper deals with assessing the impact of substitution fuel charcoal on the technological parameters of sintering and agglomerate quality. Changes in the quantity and qualitative parameters of fuel in the process of agglomeration affect the maximum sintering temperature and productivity. The maximum temperature varies with calorific value, the amount of fuel and gas-dynamic conditions in the sintered layer. When replacing fuel by solid biomass, an important parameter is also quantity of volatile substances that affect the process of agglomerate formation. Agglomerate quality is determined by its chemical composition, its physical and metallurgical properties. Effect of charcoal, as fuel substitution, on agglomerate quality indicators is evident. It was confirmed that the replacement of fuel by charcoal is only possible to a certain percentage level regarding agglomerate quality. Small amount of charcoal in the agglomeration process favorably affects the quality of agglomerate
