Tunnel Kiln

We are offering tunnel kiln for firing clay bricks, in modern brickworks, clay bricks are usually fired in a continuously fired tunnel kiln, in which the bricks move slowly through the kiln on conveyors, rails, or kiln cars to achieve consistency for all bricks.
tunnel kiln is a long structure in which only the central portion is directly heated. From the cool entrance, ware is slowly transported through the kiln, and its temperature is increased steadily as it approaches the central, hottest part of the kiln. From there, its transportation continues and the temperature is reduced until it exits the kiln at near room temperature.
the tunnel kiln is composed of of furnace body, traction system, rail, kiln-car, and firing system, hot air ventilation system, control system, etc. The design and manufacture of the tunnel kiln could be negotiated based on customers' request, including chamber dimension, working temperature, controlling method and number, traction way and speed as well as heating power. Basically, a brick kiln consists of two main parts. One is drying chamber. The other is tunnel kiln. There is no special burning system for drying chamber. The extra heat used in tunnel kiln will be feedback to drying chamber through a pipe system.
