由鞍钢设计院和柳州钢铁厂共同研制开发的柳钢3号高炉(306m~3)热风炉水热媒换热系统于1689年9月建成并一次投产试验成功,经过一年多的运行实践,证明系统具有操作简便,运行稳定、安全可靠、维护工作量小、预热效果显著的特点,当废气温度在220～350℃时,助燃空气及煤气均可由25～35℃预热到140～160℃,风温提高80℃左
Liuzhou Steel 3 blast furnace (306m ~ 3) blast furnace heat and water medium heat exchanger system jointly developed by Ansteel Design Institute and Liuzhou Steel Plant was successfully built in September 1689 and put into trial operation successfully. After more than one year of operation, It is proved that the system has the characteristics of easy operation, stable operation, safe and reliable operation, small maintenance workload and remarkable preheating effect. When the exhaust gas temperature is between 220 and 350 ℃, the combustion air and gas can be preheated from 25 to 35 ℃ to 140 to 160 ℃, air temperature increased by 80 ℃ left
