摘　　要：介绍了制约2#干熄焦的各种影响因素,现场标定2#干熄焦干熄率情况并进行了多次技术改造,改善了2#干熄焦排焦温度高、排焦不均匀以及排焦量小等问题,干熄率由88. 68%提高至93%以上,干熄焦产量逐步提高。Obstacles affecting 2# CDQ unit production are introduced. The dry quenching rate for 2# CDQ unit is calibrated on site, including technical modifications. The modified 2# CDQ unit has a lower temperature of the coke discharged, uniformly distributed coke and higher coke discharging capacity,etc., with dry quenching rate increased from 88.68% up to more than 93%. The CDQ capacity is gradually increased.
