摘　　要：根据Rayleigh准则建立了一个简化的数学模型,对Rijke燃烧装置中热源的特性位置进行了研究,避免了线性化分析方法的不足,同时将理论分析的结论和实验结果进行对比,得出Rijke燃煤装置的热源相对高度可取0.12～0.13,能够发生声波作用下的燃烧。Based on Rayleigh's criterion, this paper made a study on the heat source's location in a Rijke combustor through a simplified mathematical model and thus short comings in linearization analysis method were avoided, the theoretical conclusions were compared with experiment results, experiment showed that it's easier to make combustion under sound waves if the heat source's relative height in a coal burning combustor is between 0.12 to 0.13. Figs 3, table 1 and refs 5.
