A rough estimate of the heat balance of a roller kiln producing porcelain tiles is shown in Figure 1 where, considering a specific energy consumption of 490 kcal/kg of fired product, the percentage fractions of the heat used are illustrated. The largest amount of energy is released in the form of heat from exhausts and cooling zone chimneys.
