一种新研制出的烟囱监视器,将有助于限制燃烧过程中排出的导致酸雨的有害气体。这种烟囱监视器实际上是一个声学高温计,可以“听到”烟雾在烟囱中上升时发出的声音。 烟囱监视器的发明人约翰·克雷泊介绍,声音是一种简单的压缩空气冲击波,测量热空气的声学特性,便可计算出它的温度。根据烟雾温度的高低,能够调整燃烧过程的工艺参数, A newly developed chimney monitor will help to limit the harmful gases that cause acid rain exiting the combustion process. This chimney monitor is actually an acoustic pyrometer that “hears” the sound of smoke as it rises in the chimney. John Krepper, inventor of the chimney monitor, described the sound as a simple compressed air blast measuring the acoustic properties of hot air and calculating its temperature. According to the level of smoke temperature, can adjust the process parameters of the combustion process,
