本文采用数值模拟的方法对天然气非催化部分氧化试验燃烧器的新概念进行了评价。用于反应流计算的3D CFD模型包含包含28种物种和112个反应的详细反应机理，并通过弗莱贝格的半工业试验设施HP POX获得的数据进行了广泛验证。验证案例在61巴(A)和约1688℃的出口温度下运行。CFD模型表明，优化的燃烧器概念导致了显著更高的天然气转化率，从而允许更紧凑的反应堆设计，或者，在现有工业设施中实现更高的吞吐量。此外，还对最终燃烧器的概念进行了实验验证。光学测量表明，CFD模型能够再现复杂的三维火焰结构，并可靠地预测反应器的整体性能。
In this work, new test burner concepts for the non-catalytic partial oxidation of natural gas are evaluated using numerical modeling. The 3D CFD model for reactive flow calculations incorporates a detailed reaction mechanism containing 28 species and 112 reactions, and is extensively validated against data obtained in the semi-industrial test facility HP POX in Freiberg. The validation cases operate at 61 bar(a) and outlet temperatures of approximately 1688 K. The CFD models demonstrate that the optimized burner concepts result in a significantly higher natural gas conversion rate, which allows for a more compact reactor design or, alternatively, for a higher throughput in existing industrial facilities. In addition, the final burner concepts are tested experimentally. Optical measurements demonstrate that the CFD model is capable of reproducing the complex 3D flame structures and reliably predicting the overall performance of the reactor.
