摘　　要：采用CFD软件F luent模拟计算焦炉煤气(COG)非催化局部氧化制合成气反应器,其中湍流模型选择标准k-ε模型,热辐射选择P-1模型,用非预混模型计算化学输运和反应。反应器内组分与温度场的数值模拟结果与实验测定结果基本吻合,说明模拟结果是可信的。通过模拟可预测,当氧气与焦炉煤气进气体积比达到0.14左右时,可以获得最好的焦炉煤气的转化效果。本数值模拟可为COG非催化局部氧化制合成气进一步的工程研究与应用提供可靠的理论参考依据。The reforming reactor of coke oven gas （COG） to synthesis gas was simulated for non-catalytic selective oxidation with Fluent, a computational fluid dynamic （CFD） software. Standard k-ε model, P-1 model, and nonremixed combustion model were used for turbulence, radiation and chemical transform and reaction, respectively. The simulation results of the composition and temperature in the reforming reactor are in good agreement with those in laboratory, which proves the credibility of the simulation. The simulation can forecast the best conversion to be achieved at the volume ratio 0. 14 of inlet O2/COG in the chosen model, and provide the reference and assistance for further work and for the engineering of COG to synthesis gas through non-catalytic selective oxidation.
