摘要

限定在一口井附近。为了开发高效的共轴UCG系统，在大型模拟煤层中进行了模型UCG试验。结果表明:1)适当的氧气流入可以延长气化周期;2)通过控制氧气流入的位置可以控制燃烧/气化面积和产品气体质量;3)声发射监测是评价燃烧/气化面积的有效技术。

Control of Combustion/Gasification Area with Compact Underground Coal Gasification System

limited around a well. In order to develop co-axial UCG system with high efﬁciency, the model UCG experiment with a large-scale simulated coal seam were conducted. It has been shown that 1) the gasiﬁcation period can be extended by adopting proper oxygen inﬂow, 2) it is possible to control the combustion/gasification area and the product gas quality by controlling the position of oxygen inflow, 3) acoustic emission monitoring is an effective technique to evaluate the combustion/gasiﬁcation area.
