燃烧过程压力脉动信号的自相关分析研究

Autocorrelation Analysis of Pressure Fluctuant Signals in Combustion Process

压力脉动信号探测是锅炉诊断的重要手段。本文利用自相关函数分析燃烧过程的压力脉动信号，并根据不同燃烧状况下压力脉动自相关曲线对燃烧状况作出正确判断。本文结果对于实际燃烧设备监测与诊断系统的开发提供了帮助。

Detection of pressure fluctuant signals from combustion process is a important method for boiler diagnosis.In this paper,Autocorrelation function method is used to analyze pressure fluctuant signals and an right judgment of combustion condition can be obtained from autocorrelation analysis curves.These results are helpful to develop detection and controlling systems of combustion equipment.
