摘要/Abstract

摘要： 甲烷-烟气流量比显著影响着全氧燃烧玻璃窑炉热化学重整反应的进行。采用常压管式炉对不同甲烷-烟气流量比条件下的甲烷-烟气热化学重整反应进行了实验研究,分析了不同甲烷-烟气流量比对热化学重整反应性能的影响。结果表明:甲烷-烟气流量比显著影响着热化学重整反应有效气产量和重整过程各伴随反应占比;在相同反应时间和气体总流量条件下,当甲烷-烟气流量比为2∶1、测试温度为1 000~1 400 ℃时,热化学重整反应有效气产量和主反应占比最大;过高的甲烷-烟气流量比容易导致甲烷-烟气重整反应过程中甲烷干重整和甲烷蒸气重整反应占比降低,甲烷裂解反应占比增加;甲烷反应速率随甲烷-烟气流量比值的增大而增大,随烟气流量的增加而减小。

Abstract: The methane to flue gas flow ratio significantly affects the progress of thermochemical reforming reaction in oxy-fuel combustion glass furnaces. An experimental study was conducted on the methane and flue gas thermochemical reforming reaction under different methane to flue gas flow ratios using atmospheric pressure tube furnace, and the influences of different methane to flue gas flow ratios on thermochemical reforming reaction performance were analyzed. The results indicate that the methane to flue gas flow ratio significantly affects the effective gas yield of thermochemical reforming reaction and the proportion of each accompanying reaction in reforming process. Under the same reaction time and total gas flow rate conditions, the effective gas yield and main reaction proportion of thermochemical reforming reaction within the test temperature range of 1 000 ℃ to 1 400 ℃ are the highest when the methane to flue gas flow ratio is 2∶1. The exorbitant methane to flue gas flow ratio can easily lead to a decrease in the proportion of methane dry reforming and methane steam reforming reactions during the methane to flue gas reforming process, while an increase in the proportion of methane cracking reaction. The methane reaction rate increases with the increase of methane to flue gas flow ratio and decreases with the increase of flue gas flow rate.
