摘　　要：地下煤气化的产物除用作矿区居民家用燃料,还用内燃机组进行了地下煤气化发电的工业性试验。运用分析方法对地下煤气化发电机组的运行参数和运行特性进行了研究,得出了造成损的主要环节,进一步提出了采用先进燃气轮机的地下整体煤气化联合循环(UIGCC)发电技术有效提高地下气化煤气能量利用率,为地下煤气化发电技术的推广应用提供了技术依据。With the development of underground coal gasification technology, industrial experiments on underground coal gasification were successfully conducted in two coalmines of Xinwen Mines Group, and the products of underground coal gasification were used not only as household fuel by the residents but also for power generation with internal-combustion engines in pilot plants. In this paper, the operation parameters and performance of underground coal gasification and power generation units were investigated by an exergy analysis, and the main elements of exergy loss were acquired and analyzed. In addition, the underground integrated gasification combined cycle (UIGCC) power generation with the gas turbine was suggested to enhance the energy efficiency, which provide the technical basis for the application of underground coal gasification and power generation technology in China.
