摘要
介绍柳钢1号高炉A高风温组合换热系统的构成、工艺流程,及其应用效果:回收热风炉烟气的余热,煤气预热温度到180℃,助燃空气预热到400℃,仅用高炉煤气就获得1200℃的高风温。
The configuration, process flow of combined heat transfer system A at high hot blasting tem- perature of No.1 Blast Furnace and its application effects were introduced： waste heat of flue gases of hot- blast stove was recovered, the preheating temperature of gas was 180 ℃, the preheating temperature of com- bustion air was 400 ℃, and then it can get high hot blasting temperature of 1 200 ℃ with blast furnace gas only.
