摘要
对比分析了空气蒸汽连续法气化工艺条件下华亭煤现场实测所得的地下气化指标与采用综合计算法模拟得到的固定床气化指标。结果表明,固定床气化所得到的高热值气体量(如CH4、CO)大于地下气化所得量,固定床气化碳进入煤气的转化效率要高于地下气碳转化效率。推测地下气化过程中,地下水参与了气化的反应,并导致地下气化所得的氢气量大于固定床气化所得量。
A comparison analysis was conducted on the underground coal gasification index obtained from the site of Hnatong Mine under the air and steam continued method gasification technique and the fixed bed gasification obtained from the simulation with the comprehensive calculation method, the results showed that the high calorific value （such as CH4 and CO） obtained from the fixed bed gasification was higher than the value from underground gasification and the gas conversion rate of the fixed bed gasified carbon was higher than the carbon conversion rate of the underground gasification. By inference of the underground gasification process, underground water was participated the reaction of the gasification and cased the hydrogen content obtained from the underground gasification was higher than the content from the fixed bed gasification.
