摘要:

介绍了某140 t/h干熄焦的长寿化改造方案,及改造前后干熄焦生产情况。改造后干熄焦生产运行稳定,冷却区落料不均问题得到解决,排焦温度降低了15 ℃,锅炉入口吸力下降,干熄焦系统阻力减少,生产运行成本降低。

Abstract:

This paper introduces an upgrading proposal of a 140 t/h CDQ system,and presents differences in production before and after the modification.After the upgrade,the CDQ system steadily operated.The problem of uneven drops in the cooling zone was resolved.The temperature of discharged coke was lowered by 15 ℃.The suction at inlet of the boiler and the resistance of the CDQ system were also reduced.These helped to lower the operating costs of the CDQ system.
