| 摘 要： | 对O2/CO2燃烧方式下反应器内CH4火焰的温度特性进行了研究，结果表明：在还原性气氛下，初始CO2浓度的升高对CH4火焰高温区的影响是消极的，在完全燃烧和氧化性气氛下，初始CO2浓度的存在对CH4火焰温度分布的影响则比较复杂，存在一个初始CO2浓度临界点，在此临界点前后，CO2浓度对CH4火焰的温度水平分别有着不同的影响；同时在高浓度的CO2气氛下，整个火焰的温度分布趋于平均化。

| Abstract: | The temperature characteristics of CH_4 flame in O_2/CO_2 atmosphere are investigated in the paper. The results indicate that the concentration of initial CO_2 has negative effect on the high temperature area in CH_4 flame in the reducing atmosphere. The effect of initial CO_2 concentration on the flame temperature of CH_4 is complex in the oxidizing atmosphere, there being a critical concentration. The effect, however, of CO_2 concentration is different before and after the critical value while the distribution of temperature is relatively uniform under high CO_2 atmosphere. |
