Thermal acoustic tomography [PDF]
Monitoring of furnace exit gas temperature is important for the efficient maintenance of operating parameters within utility boilers. Since gas temperature is related to the acoustic wave speed, a noninvasive technique based on transit time measurements along selected paths of known length can be used to develop an analytical model capable of ...
