Abstract (en)
The process provides that the material is introduced into a furnace with a first prefiring zone, a second firing zone and third cooling zone. Kiln cars move forward in the furnace on which refractory surfaces carrying the load (2) are realized in such a manner as to leave at least one longitudinal interspace (3). In the ceiling of the first zone and in correspondance with the said longitudinal interspace (3) is formed a niche (3 min ) provided with burners (4), the gases coming from which are divided and deflected by means of deflectors (6) from a vertical passage into two horizontal passages in opposite directions. In the second zone, the firing is realized by combustion gases which are fed in horizontally and over the product to be fired, together with the heat supplied from the air originating from the cooling zone, and the distance between the ceiling and the car deck (5 min ) of kiln cars is reduced to a very small amount. Therefore, this results in the greatest reduction possible of the external air volume injected into a tunnel furnace resulting in improvement of the efficiency.
