摘要:
在自主搭建的小型规模旋风渣膜煤气化装置上,开展了对褐煤气化特性的实验研究,重点研究了气化炉负荷、一次风氛围、氧煤比以及蒸汽煤比对粗煤气中有效组分含量、碳转化率以及冷煤气效率的影响.研究表明,随着气化炉运行负荷的增加,粗煤气中有效组分含量、碳转化率以及冷煤气效率均先增加后趋于稳定;用CO2+O2 送粉相比于用空气送粉,粗煤气中有效组分含量增加、碳转化率以及冷煤气效率升高;随着氧煤比的增大,粗煤气中CO 含量和冷煤气效率先增加后减少,当氧煤比为0.9 时两者均达到最大值;随着蒸汽煤比的增加,粗煤气中CO含量、碳转化率、冷煤气效率均逐步减少.
Abstract:
Experimental study on the gasification characteristics of lignite was carried out on a small-scale cyclone slagging gasifier,focusing on the effects of gasifier load,primary air atmosphere,ratio of oxygen to coal and ratio of steam to coal on the content of CO and H2,carbon conversion and cold gas efficiency.Experimental results show that with the increase of gasifier load,the content of CO and H2,carbon conversion and cold gas efficiency first increase and then tend to be stable.The content of CO and H2,carbon conversion and cold gas efficiency are greater for CO2 and O2 than those for air.With the increase of ratio of oxygen to coal,the content of CO and cold gas efficiency increase first and then decrease,and they both reach the maximum when the ratio of oxygen to coal is 0.9.CO content,carbon conversion and cold gas efficiency gradually decrease with the increase of ratio of steam to coal.
