摘　　要：为更有效地排除锅炉燃烧系统中的声耦合燃烧振荡问题,理论分析了锅炉简化模型的声学固有频率,同时结合实例研究了较复杂系统的耦合模态,指出锅炉燃烧设备声学固有频率的复杂性,总结了计算锅炉固有频率和模态的一般方法。The acoustic natural frequency of the simplified boiler model is analyzed in order to efficiently eliminate the acoustically coupled combustion oscillations in the boiler combustion system. The complicated acoustic modes are studied with examples showing the complexity of the acoustic natural frequencies. The general methods to calculate the natural frequencies of the boiler system are summarized.
