| 摘 要： | 用实验室固定床反应器模拟合成气制备炉，考察了该工艺中不同因素对火焰区温度的影响。实验中首先确定了使火焰区温度最低时的甲烷和氧气相对入口位置，然后在此条件下分别考察了进料中H2O/O2和CH4/O2摩尔比变化对火焰区温度的影响。结果表明，甲烷和氧气相对入口位置平齐时火焰区温度最低，火焰区温度均随进料中CH4/O2和H2O/O2摩尔比的增大而降低。

| Abstract: | The temperature control of the flame zone plays an important role for synthesis gas preparation by the co-gasification of natural gas & coal. In this paper the factors affecting the temperature of the flame zone were investigated using a laboratory scale fixed bed reactor to simulate the industrial furnace for synthesis gas preparation. The inlet positions of methane and oxygen that make the flame minimum temperature were first investigated. Then the effects of the ratio of H_2O/O_2 and CH_4/O_2 in feedstock on the flame temperature were studied respectively. The experimental results show that the flame temperature is the lowest when the inlet position of CH_4 and O_2 is at the same level. Under this condition, the flame temperature decreases when the ratio of CH_4/O_2 and/or H_2O/O_2 is increased. |
