Heat transfer inside the tunnel kiln, which serves for producing ceramic bodies by reactive sintering of kaolinite raw material, has been modelled. The procedure for solving the model as well as adequate computer program have been suggested in order to achieve two goals: determining of (optimal) length of thermal treatment for required temperature in the center of the body and vice versa, calculating the temperature in the center of the body for given length of process. Also, correlation which defines temperature change in the center of the body along the tunnel was determined. Computer program was applied to the tunnel kiln already installed in JGM-Kanjiza and optimal length of thermal treatment was determined. The suggestion to shorten the process in the examined kiln was given.
