煤炭地下气化新工艺的试验研究

Test Study on the New Technique of the Underground Coal Gasification

提出了煤炭地下气化工业性试验的新工艺，指出了传统地下气化炉的弊端，阐述了长通道、大断面地下气化炉的优越性，并对两阶段、双火源、反向燃烧、多功能钻孔及压抽相结合新技术工艺进行了介绍及试验结果分析．工业性试验的圆满成功，表明我国煤炭地下气化向商业化应用迈出了一大步．进一步证明了煤炭地下气化新工艺的合理性和可行性．

The new technique of the industrialization test on underground coal gasification is suggested. The malpractice for traditional underground gasification stove is pointed out, the superiority for the long tunnel large section underground gasification furnace is explained, and the new technology craft of two stage, double fire source, inverse direction combustion gasification, multifunction holes, and pressing and pumping combination is introducted, and the test results are analysed. The perfect success of the industrialization indicates that the underground coal gasification has taken a long step forward commercialization application in our country, and it further proves the reasonableness and feasibility of the new technique on underground coal gasification.
