%X ABSTRACTCarrying out experiments in tunnel kilns are difficult and costly. Due to the largelength of such kilns that sometimes reaches 180 meters. That causes theproduction cycle takes some days. Therefore, a mathematical model is needed tosimulate the heat transfer process in such kilns. In this contribution, a simple shapeproduct (vitrified clay pipes) was used in the modeling, in order to simplify thecomplexity of the process. The bvp4c code was used to solve all ordinary differentialequations (ODEs) of the model to obtain temperature profiles of the system usingMatlab. Results revealed that: the excess air number has a higher impact on the heattransfer process inside the kiln. Consequently, the thermal heating of products couldbe easily controlled, by changing the excess air values. Heat transfer coefficientenhancement is a key parameter to save the energy consumption within the kiln.
