摘  要:通过建立干熄炉、干熄焦余热锅炉及干熄焦系统热平衡模型,对鞍钢股份有限公司炼焦总厂190 t/h干熄焦系统进行了热平衡测试与计算,并对热平衡测试结果进行了分析。针对干熄焦系统存在的气料比过大、预存室压力低、热管换热器效率低等问题,提出了适当降低气料比,控制导入空气量和放散气体量,对热管换热器进行密封、清灰、优化的建议。By establishing the heat balance model in terms of the coke dry quenching(CDQ)furnace,the CDQ waste heat boiler and the CDQ system,the heat balance test and calculation for the CDQ system with the capacity of 190 t/h in General Coking Plant of Angang Steel Co.,Ltd.were carried out,and then the test results of heat balance were analyzed.In view of the problems occurred in CDQ system,such as excessive ratio on gas-to-material,low pressure in pre-storage chamber and low efficiency of the heat pipe heat-exchanger,some suggestions were proposed,including appropriately reducing the ratio on gas-to-material,controlling the amount of introduced air and released gas as well as sealing,cleaning and optimizing the heat pipe heat-exchanger.
