宝钢一号高炉余热回收工程,自去年11月投入试运行以来,今年上半年已节约焦炉煤气1100万米~3,价值165万元。这是继法国敦刻尔克高炉之后,世界上第2座4000米~3以上特大型高炉成功地采用水热媒方式回收余热。宝钢一号高炉余热回收工程设计每小时节约焦炉煤气3000～4000米~3,目前已达到设计要求。它投入使用后,每年可获净利470万元。余热回收工程投资1000万元,只需两年多即可收回。
Baosteel Blast Furnace Waste Heat Recovery Project, put into trial operation since last November, the first half of this year has been saving 11 million meters coke oven gas ~ 3, the value of 1.65 million yuan. This is the second after the Dunkirk blast furnace in France, the world’s second 4000 m ~ 3 extra large blast furnace successfully using hydrothermal media to recover waste heat. Baosteel One blast furnace heat recovery project designed to save coke oven gas per hour 3000 ~ 4000 m ~ 3, has now reached the design requirements. After it is put into use, it will receive a net profit of 4.7 million yuan each year. Waste heat recovery project invested 10 million yuan, just two years to recover.
