钢铁行业“三气”的特点是什么?_焦炉高炉转炉煤气浓度监测_天禹智控
钢铁行业“三气”的特点是什么?
2020.09.05
一、焦炉煤气的特点
(1)焦炉煤气的气体组成:CH4:22~26%;CO2:2~4%;CO:6~10%;H2:55~60%;N2:1~3%
(2)焦炉煤气热值:4100~4400大卡/标方
  总结:富氢富甲烷氢多少碳

高炉煤气特点
(1)焦炉煤气的气体组成:CO2:20~25%;CO:22~30%;H2:1~3%;N2:50~57%
(2)焦炉煤气热值:750~900大卡/标方
  总结:热值不高氮含量高

三、转炉煤气特点
(1)焦炉煤气的气体组成:CO2:15~20%;CO:40~65%;H2:1~3%;N2:10~35%
(2)焦炉煤气热值:1500~2000大卡/标方
  总结:热值适中多碳少氢
