Abstract
ABSTRACT
Carrying out experiments in tunnel kilns are difficult and costly. Due to the large
length of such kilns that sometimes reaches 180 meters. That causes the
production cycle takes some days. Therefore, a mathematical model is needed to
simulate the heat transfer process in such kilns. In this contribution, a simple shape
product (vitrified clay pipes) was used in the modeling, in order to simplify the
complexity of the process. The bvp4c code was used to solve all ordinary differential
equations (ODEs) of the model to obtain temperature profiles of the system using
Matlab. Results revealed that: the excess air number has a higher impact on the heat
transfer process inside the kiln. Consequently, the thermal heating of products could
be easily controlled, by changing the excess air values. Heat transfer coefficient
enhancement is a key parameter to save the energy consumption within the kiln.
