In the production of high quality materials by a heat treatment, it is indispensable to accurately predict the temperature inside the furnaces being employed. In this work we develop a turbulent combustion model for the heat being released by gas burners inside a shaft kiln. Turbulent combustion is the strongly coupled phenomena of the chemically reacting fuel and oxygen in a turbulent flow. We developed a model for both the empty kiln and the kiln filled with clay-like material being processed. Numerical results for the empty kiln show a strong temperature gradient near the walls close to the inlet of the kiln. Further work is required to refine the model representing the material inside the oven and its absorption of heat.
