| 摘 要： | 超低浓度煤层气由于甲烷含量低、浓度变化大而较难加以利用。采用实验和数值模拟的方法，研究了超低浓度煤层气在流化床中的燃烧，分析了床层温度、甲烷体积浓度，流化风速对甲烷燃烧效率的影响，并用数学模型预测了甲烷沿床层高度方向的分布。研究表明，数学模型和实验数据吻合较好。床层温度是煤层气燃烧反应的关键因素，甲烷的转化率随着床层温...

| Abstract: | The ultra-low concentration coal bed methane is difficult to utilize due to its low methane content and fluctuated concentration.Coal bed methane combustion in a fluidized bed was studied experimentally and numerically.The effects of bed temperature,methane volumetric concentration and fluidized velocity on methane conversion were analyzed.The methane profile along bed height was predicted with the mathematical model.The results show that the model compares reasonably well with experimental data.Bed tempera... |
