Resumo

Сomparison of traditional tunnel kilns energy and production efficiency, massively used in domestic brick factories, with chamber and ring kiln units has been carried out. It is shown that the latter are conditionally thermotechnically more efficient, their specific fuel consumption per 1 ton of fired product corresponds to the Soviet norms and is significantly lower than the best available technologies. A new design of tunnel kiln with chamber firing mode is proposed, it allows setting required heating, holding or temperature reduction rate in each chamber, while maintaining high temperature field uniformity throughout the cage volume. High environmental performance is achieved due to separate flue gas extraction from the firing channel individual chambers.
