| 摘 要： | 燃烧过程中减排CO2已成为当前研究热点,化学链置换燃烧(CLC)可在没有额外能耗的前提下,将CO2从燃烧产物中分离出来,是一种崭新的洁净燃烧方式。目前国内外关于CLC模型的相关文献基本没有报道,基于欧拉多相流和化学动力学基础,利用计算流体力学软件(FLUENT)首次建立了CLC燃料反应器(CaSO4和H2)的反应动力学模型,并针对氢气的分压和床内反应温度对化学链燃烧的影响进行了相关的数值模拟。结果表明:氢气的分压和床内温度是影响化学链燃烧的重要参数,分压和温度的升高,提高了氢气的转化率。

| Abstract: | How to reduce the CO2 emission in the combustion process has become the current research hotspot.Chemical-looping combustion(CLC) can provide a sequestration ready CO2 stream with no additional energy required for separation,so it has been proposed as a new clean combustion technology.So far there has been little literature about CLC numerical modeling.In this work,based on the fundamentals of Euler multiphase flow and chemical dynamics,the reaction kinetic model of the CLC fuel reactor(CaSO4+H2) is develop... |
