摘　　要：为了了解程潮矿业公司球团厂链篦机-回转窑-环冷机系统三大主机的热工状态,对系统的物料、风量及热量平衡进行了考察与分析,并为优化现场热工制度提出了合理建议。结果表明,链篦机机漏风率为10.86%,链篦机、回转窑和环冷机热损失率分别为5.38%、12.09%和1.87%,需针对风箱和烟罩密封性进行检修,降低漏风率和热损失,对回转窑内耐火砖进行实时监测,定期更换破损耐火砖,降低窑内散热。In order to find out the thermal state on three main engines for the chain grate-rotary kiln-ring cooler system at Pellet Plant of Chengchao Mining Company,the balance of materials,air volume and heat amount in terms of the system were investigated and analyzed,and based on that suitable suggestions were put forward for optimizing the on-site thermal system.The analytival results showed that the air leakage rate of the chain grate was 10.86%,and their heat loss rates in terms of the chain grate,rotary kiln and ring cooler were 5.38%,12.09%and 1.87%respectively.So it was concluded that the complete overhaul should be carried out in view of the sealability of both bellows and hoods so as to reduce the air leakage rate and heat loss,while the refractory bricks were monitored in the rotary kiln in real time for replacing the damaged refractory bricks regularly so as to reduce the heat loss in the kiln.
