Abstract: The reconstruction algorithm plays a key role in reconstructing acoustically the flame temperature field in coal-burning boiler hearth. A new algorithm is proposed to realize the image reconstruction of complex temperature field, i.e., adding a prior information matrix to the reconstruction of temperature field to realize the image reconstruction of complex temperature field with less measured data of time for sound transmission. Experiments based on this algorithm were done on the experimental setup we developed for the reconstruction of actual flash flame temperature field. The results showed that the new algorithm is available to realize the field image reconstruction of complex temperature field.
