焦炉烟气余热蒸氨系统在柳钢的开发与应用

Research and application of residual heat ammonia evaporation system for coke oven flue gas in Liugang

焦炉烟气是一种低品位热源,经脱硫脱硝净化后,其余热可用于间接蒸氨。对焦炉烟气余热间接蒸氨的工艺流程、主要设备、操作参数等要点进行了研究,给出了合理的工艺流程和控制参数,实现了焦炉烟气余热的有效利用。

Coke oven flue gas is a low-grade heat source that can be used for indirect ammonia evaporation after desulfurization and denitrification purification.The author has studied the process flow,main equipment,operating parameters,and other key points of indirect ammonia evaporation from coke oven flue gas waste heat,and provided reasonable process flow and control parameters,achieving effective utilization of coke oven flue gas waste heat.
