摘　　要：提出了一种将催化燃烧和预混燃烧方式结合在一起的催化-预混混合燃烧室结构,对燃烧室在不同工况下的运行特性进行了分析。采用详细反应机理及二维分布参数的流动模型建立了催化-预混混合燃烧室数学模型,应用所建立的数学模型分析了催化-预混混合燃烧室在设计工况和非设计工况时的温度分布及NOx排放特性,将设计工况时的运行结果与文献[11]实验结果进行了对比。研究表明:在设计工况燃烧室温度-燃料转化率与文献[11]的实验结果基本吻合;在不同运行工况下,催化-预混混合燃烧室的温度分布没有大的波动,NOx排放主要来源于预燃室,在不同工况下都低于15 mg/m3,达到了超低排放水平。The structure of catalytic-premixed hybrid combustor has been mentioned which combines the catalytic combustion and premixed combustion. The performance of hybrid combustor has been studied in different conditions. The catalytic-premixed hybrid combustor model has been established with the detailed reaction mechanism and 2D distribution parameters flow model. The temperature distribution and NO x emission at design and off-design conditions are studied using the model,and the model results are compared with the experiment results in reference[11]at the design point. The results show that,at the design point,the performance of hybrid combustor is basic? agreement with the experimental result in the reference[11]. There is no major fluctuations of the temperature distribution at different operation conditions,NO x is mainly from the pre-combusotr. The NO x emission is always lower than 15 mg / m3 which achieves the ultra low emission standard.
