摘　　要：研究了不同富氧浓度下,出口煤气有效组分含量、热值、产气率及热效率的变化规律.试验结果表明:随着氧气浓度的增加,煤气中H2,CO含量及热值增加,但当O2浓度大于84%时,煤气中有效气体组分含量及热值上升幅度减小;随着富氧浓度的提高煤气产率下降,气化效率在44.47%~64.91%之间;薄煤层富氧-水蒸汽气化能够连续生产有效气体组分(H2+CO+CH4)大于59.56%、热值在8.2 MJ/m3以上的煤气,并能有效地控制气化炉温度,保持煤气组分和热值的稳定.The variations laws of the contents of the main components,the heat value,the yield and the thermal efficiency of the gas were investigated.The results show that there is an upward trend for the contents of H2 and CO and the heat value of the gas with the increase of the content of oxygen,but the upward trend becomes slow when the content of oxygen goes beyond 84%.The gasification efficiency goes from 44.47% to 64.91%.During the continuously process of rich-oxygen-steam UCG,the contents of the main componen...
