Tunnel-type kiln for firing chamotte parts with hot air feed to burners

Conclusion

Experience in operating tunnel-type No. 2 at the Borovichi Combine, designed by the All-Union Institute of Refractories, has confirmed the advisability of feeding hot air to the burners through injectors, and spacing the burners in the high-temperature zone at intervals of 1.5 m, leaving corresponding gaps in the batching on the car.

Research work and adjustment are required in order to reduce the temperature of the parts coming from the kiln, to level the temperature throughout the length and width of the batching, and also to cut down heat losses; it is absolutely essential to handle cars with wares at elevated temperatures correctly.
