摘要
声学法锅炉温度场检测技术是近年来发展起来的一项新技术。介绍了声学温度场检测技术的声学原理和通过测量声波传感器间的声波传播时间 ,然后利用最小二乘原理重建温度场的测量方法 ,并进行了炉膛截面二维温度场重建仿真。对声学烟温测量方法在锅炉烟温测量中的应用及存在的问题进行了分析和讨论。
Gas temperature field measurement using acoustic pyrometer was a new technique a nd developed recently. The basic principle and measuring the sound wave fly time between transmitter and receiver to reconstruct two dimensional temperature fie ld in furnace by least square regularizing algorithm method are presented in thi s paper, and gives the reconstruction simulation. The application and some probl ems of this method are analyzed.
