摘要
本文介绍了燃烧压力场波动产生的机理及其功率谱密度函数测量方法与仪器,分析了在国产300MW电站锅炉上实测的结果,指出国产300MW锅炉燃烧压力场的波动主要由燃烧振荡引起.其功率谱密度函数与燃烧功率有关。
The mechanism of pressure fluctuation in the combustion field and instrumentation for measuring its power spectrum density function are presented with discussions oftest results of a domestic 300 MW power boiler. The paper points out that pressure fluctuations of a domestic 300 MW boiler are mainly caused by combustion instability with the former's power spectrum density function closely related to combustion intensity.
