多点两阶段煤炭地下气化方法
Method of Multi-point Two-stage Underground Coal Gasification (TSUCG)
摘要
Abstract
In view of the problem of the unsteadiness of coal gas heat value, which exists in the process of the underground coal gasification (UCG) in the steep coal seam, the technique of multi-point TSUCG is suggested. The model test system is introduced. The method of multi-point two-stage underground gasification is also expounded.The time ratio of the first stage to the second one, the heat value and compositions of gas produced and the velocity of gasification are studied, and the test results are analysed. It is shown that the method of multi-point TSUCG makes the time, when yields water gas of high heat value, prolong by 0.67～1.5 times compared with that of fixed point supplying wind or steam. Thereby, it will provide an important theoretical foundation for the design of the production and technological parameters in the process of the test on the spot of the UCG.关键词
