| 摘 要： | 针对目前提倡的煤部分气化燃烧系统集成优化联合生产煤气和热能的新概念,在不同温度下制得四种煤的半焦,通过热天平燃烧试验研究了半焦的燃烧特性,考察了煤种和制备温度对半焦燃烧特性的影响.试验结果表明:煤种不同,所制得半焦燃烧特性不同;相同煤种制得半焦,随制备温度升高,半焦着火温度上升,燃烧活化能增加,燃烧反应活性降低.

| Abstract: | There is substantial interest in the integration and optimum of coal partial gasification and combustion system to generate coal gas and thermal energy.The semicoke from four different coal types was prepared under different temperatures.The effect of coal type and preparation temperature on the combustion characteristics of semicoke were investigated by thermobalance.The experimental results show that the combustion characteristics of semicoke from different coal type are very different each other.With the increasing of preparation temperature,the ignition temperature of semicoke from same coal type increases and its activation energy also increases while its reactivity decreases. |
