摘要
Abstract
Addressing the issues of significant flue gas discharge and low waste heat utilization efficiency in the circular cooler during pellet production at a steel plant,a model of the circular cooler system was established and simulation calculations were performed.By varying the bed poros-ity,bed height,and the outlet air volume of each process section of the circular cooler,the influ-ence of these parameters on the cooling process of the pellets was investigated.The results indicate that within the bed porosity range of 0.35 to 0.60,increasing porosity leads to a decrease in outlet flue gas temperature,which is unfavorable for waste heat recovery.Therefore,it is recommended to control bed porosity around 0.40.The outlet flue gas temperature of each process section increases with increasing bed height.To ensure pellet quality,a bed height of approximately 0.80 m is recom-mended after comprehensive consideration.When the outlet flue gas temperature of Circular Cooler Section Ⅲ is low,priority should be given to regulating the fan opening of Circular Cooler Section Ⅱ.关键词
