Thermal acoustic tomography [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1990
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 ...
