| Abstract: | 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. |
