摘要:
通过地下气化模型试验,获得了华亭煤纯氧-水蒸汽地下气化过程的一般规律.研究了汽氧比对煤气组成的影响、气化过程的稳定性以及试验条件下的煤层气化速率变化,进行了相同条件下的物料衡算.试验结果表明,纯氧煤炭地下气化,可以利用煤层含水或顶板淋水生产水煤气.华亭煤纯氧-水蒸汽地下气化可以获得合格的合成氨原料气,但需根据气化工作面的移动及煤气组成变化,采用移动点供风气化维持气化过程连续稳定进行.气化过程的物料衡算可以用来预测气化煤气的基本组成.汽氧比影响煤气组成变化,试验条件下适宜的汽氧比范围为1.5~2.煤层气化速率在供风点附近出现最大值,试验条件下的平均水平气化速率为4 cm/h,平均横向气化速率为1.5 cm/h.
Abstract:
Based on underground coal gasification(UCG)model test, the regularity of Huating coal underground gasification with oxygen-steam as agent was obtained. The influence of ratio of steam to oxygen on gas composition, gasification stability, and change of gasification velocity were studied. In the same time mass balance of the UCG process was conducted. The results show that the water gas can be produced through oxygen gasification using the water contained in coal seam and coal roof. Underground gasification of Huating coal with oxygen-steam as gasification agent could provide raw material for ammonia synthesis, but moving agent supply is needed to maintain the process according to the movement of fire face and change of gas composition. Mass balance can be used for prediction of gas composition. The ratio of steam to oxygen will affect gas quality and optimum steam/oxygen ratio is 1.5-2 in the test condition. The gasification velocity has the maximum value near the oxygen-supply points and the average horizontal gasification velocity is 4 cm/h while the extending velocity is 1.5 cm/h.
