摘　　要：以宝钢二炼钢250 t转炉煤气回收系统为背景,结合转炉煤气成分变化曲线从理论上分析了提高煤气回收量的基本途径,研究了转炉工序设备条件、原料条件、空气吸入量、回收条件、供氧强度等因素对转炉煤气回收量的影响,其中空气吸入量、回收条件、供氧强度等因素的影响尤为显著。从完善软硬件设备等方面提出了提高二炼钢转炉煤气回收水平的具体措施,实施后可取得很好的节能效果。The basic approaches to improve gas recovery ratio were analyzed in theory based on converter gas recov ery system of Baosteel No. 2 steel making plant. The effect of following factors such as converter conditions, raw material supply, air suction rate, recovery conditions, and intensity of oxygen blowing on converter gas recovery ratio was studied. And the effects of air suction rate, recovery conditions and intensity of oxygen blowing are remarkable. The physical measures are put forward for modification of hard and soft ware of converter gas recovery system, and good results can be achieved.
