锅炉炉内管道泄漏的声学模型

Acoustic Model for Detection of Internal Tube Leakage in Boilers

各大电厂锅炉管道泄漏事故给国家造成巨大的经济损失，文中利用声学方法对锅炉炉内管道泄漏进行监测，并论述了声强与泄漏口径，声强与管内工质，声强与出口速度之间的关系，对声信号在炉内衰减情况作了一定的分析。

Describes monitoring of tubes leakage in boilers by means of acoustic method. The relationshipe between the sound intensity to the diameter of leakage openings,working medium in tubes and the leakage speed are presented. The attenuation sitution of the sound signal within the boiler is analyzed as well.
