1前言柳钢拥有3座80 000 m3转炉煤气柜,转炉煤气吨钢回收量为110 m3。虽然回收水平站上了新台阶,但是转炉煤气系统还存在如下问题:(1)用户少,调整方式少,在大用户检修时,转炉煤气大量拒收,造成能源浪费。(2)因1号柜外送煤气主管管径为1 300 mm,偏小,导致1号柜的风机出口压力偏高,1号柜存在较多拒收情况。为解决上述问题,综合考虑高炉煤气总量不足的状
1 Introduction Liuzhou Iron and Steel has three 80,000 m3 converter gas tank, converter gas tons of steel recovery of 110 m3. Although the recycling level to a new level, but the converter gas system still has the following problems: (1) fewer users, less adjustment, maintenance of large users, a large number of rejected converter gas, resulting in energy waste. (2) Because the pipe size of the No. 1 external gas delivery pipe is 1 300 mm, which is too small, the outlet pressure of the fan in the No. 1 cabinet is too high, and there is more rejection of the No. 1 cabinet. In order to solve the above problems, considering the total amount of blast furnace gas shortage
