An algorithm is proposed to solve a nonlinear problem of the band model when it is employed to estimate the absorption coefficient of long optical depth by a CT (computer tomography) pyrometry. This algorithm uses the statistical model for the band model and the Curtis-Godson model for the estimation of absorption of the non-uniform temperature region. The data of the absorption coefficient was calculated by RADCAL which is based on the Malkmus theory. This algorithm is applied to the two-band absorption CT employing carbon monoxide as an absorption medium which is contained with high concentration in burnt gases. The algorithm is verified experimentally not only by the ideal burner but also by home use practical burners. The accuracy of the temperature is good enough but that of concentration of carbon dioxide is considerably higher than the expected value.
