The acoustic thermometry has many advantages, compared with conventional methods of temperature measurements. For this technology, the sound field in normal temperature state of the boiler was simulated; acoustic source signal obtained the pseudo random sequence signal and time delay estimation selected the weighted cross-correlation method. Experiments show that when the boiler is not running, the sound field is enclosure sound field in the furnace. The weighted cross-correlation method can restrain the reverberation and obtain the accurate time delay estimation.
