Contours of Air and Brick Temperatures inside a Tunnel Kiln

We present, in this work, the main results obtained from a two-dimensional numerical modeling of a tunnel kiln used for production hollow bricks. The results obtained made it possible to present contours of the temperature inside a tunnel kiln using a home-made two-dimensional code written with the open-source software SCILAB. The results showed the existence of a vertical temperature gradient in the brick stacks which can affect the final quality of the baked products.
