摘　　要：以某炼焦企业采用焦炉烟气回配技术为典型案例,结合烟气污染物情况和焦炉烟气参数特点,研究运行参数进一步优化,包括利用周转时间的控制,调整热风炉运行温度,降低喷氨量等方法,使得生成的焦炉烟气NO_(X)含量降低,排放的焦炉烟气NO_X含量稳定在 45~60mg/m^(3) 以下。氮氧化物减排效果显著,实现了氮氧化物排放的源头治理,达到提高社会环保效益和企业经济效益的目的。Taking the application of the recirculation of coke oven flue gas in a coking enterprise as a typical case,combined the flue gas pollution situation and the characteristics of coke oven flue gas parameters,this paper discusses the optimization of the parameters by controlling the cycle-time,adjusting the temperature of hot blast stove and reducing ammonia rate,etc.The produced NOX content of coke oven fuel gas will drop,and its emitted content will stabilize blow 45-60 mg/m3.The NOx emission is so remarkably reduced that the NOx emission control from the source can be realized to achieve the purpose of improving social environmental benefits and the enterprise's economic benefits.
