摘　　要：为回收焦炉荒煤气部分余热,利用超低温热水型溴化锂制冷技术回收初冷器高温段循环水的余热,夏季制冷工况,利用高温段循环水的余热替代蒸汽或煤气制冷;冬季制热工况,回收中温段循环水余热增加采暖供热面积。该技术应用后,机组运行稳定,实现了夏季焦炉煤气的自给式制冷、采暖季进一步回收中温段余热节约蒸汽的目的,年综合效益445万元。For recovering part of the waste heat in raw gas using ultra-low temperature hot water type lithium bromide refrigeration technology recycles waste heat in the circulating water of high temperature stage of primary cooler. The refrigeration working condition in summer is to refrigerate to replace steam or gas by waste heat in recycling water of high temperature stage, and the heating working condition in winter is to recycle waste heat in recycling water of medium temperature stage to increase the supplying heat area. After this technology is application, the machine set operation was stable, the aim of self-refrigeration of coke oven gas in summer and saving of steam by recycling waste heat in medium stage in winter were achieved, and comprehensive benefit is 4.45 millions Yuan RMB per year.
