Abstract


Reducing the consumption of energy is one of the main challenges of the global economy and this is the aim of our research on “optimizing the consumption of a pottery kiln in Salé (Oulja)”. Faced with global competition and rapidly changing technology, potters must reconcile the improvement of the quality of their products with the reduction of energy consumption. In this article we will identify the different types of furnaces used in baking pottery pieces. This section will address the different heat transfer phenomena involved in this type of furnaces. Experimental study shows that the energy consumption is high and the excess consumption is due to heat loss of the combustion gas escaping from the furnace through the chimney. The recovery of this heat can lead to big energy saving. A program based on the finite volume method and the double scanning, was developed. It calculates the temperature profile of the inner and outer sides of the kiln walls and hense deduce losses through the chimney. Model validation is made by comparing the experimentally measured temperatures and those obtained by the simulation program.
