摘　　要：对比分析回转窑和罐式炉不同的冷却方式,采用冷却效率高,并且对高温煅后焦热量可以余热利用的冷却技术正在成为新的发展方向。回转窑间接冷却不仅可以产生90℃的热水,而且还能解决直接喷淋冷却带来的焦粒粉化问题,是新建或者改造项目的优选工艺。罐式炉汽化冷却方式可以产生250~300kg/t-CPC的饱和蒸汽,经济性明显,是降低双碳排放的重要技术,但是产业化应用还需要解决水套材料、寿命方面的问题。Comparing and analyzing different cooling methods of rotary kilns and vertical shaft furnaces,the use of cooling technologies with high cooling efficiency and the utilization of waste heat from high-temperature calcined coke is becoming a new development direction.The indirect cooling of rotary kiln can not only generate hot water at 90℃,but also address the problem of coke particle pulverization caused by the direct spray cooling.It is the preferred process for new construction or renovation projects.The saturated steam produced by vaporization cooling method from vertical shaft furnace is 250~300 kg/t-CPC,which has obvious economic benefits and is an important technology for reducing carbon emission.However,industrial application still needs to solve materials and lifespan problem of water jacket.
