In this paper, the FIR low-pass digital filtering method is first introduced for reducing the effects of noise signals in the experiment of velocity measurement of high-temperature flue gas flowing in pipe. The experimental results indicated that, only one peak presents in the cross-correlation graph, which is in good agreement with theoretical analysis result. Secondly, the temperature and pressure pulse signals of the high-temperature flue gas, obtained by thermocouple and pressure sensor, are introduced to explain the applicability of sensor characteristics.

本文介绍在测量管内流动的高温烟气流速的实验中采用FIR低通数字滤波器滤波方法可以排除干扰信号的影响的研究，实验结果证明，经过滤波处理后的信号互相关函数的图形不会出现大小相当的多个峰值，符合理论分析的结果；其次，本文还介绍了用热电偶和压力传感器采集的烟气温度和压力脉动信号，分析了传感器特性对相关测速的适应性。
