Tunnel kiln is a continuous industrial kiln, which looks like a tunnel and consists of a kiln body, conveying equipment, combustion system, ventilation system and control system. Its working principle is to place the green body on the kiln car, and through the slow movement of the kiln car in the tunnel, the green body is fired through preheating, firing, cooling and other stages in sequence. It has the advantages of high production efficiency, stable product quality, low energy consumption and high degree of automation, and is widely used in large-scale production in industries such as ceramics, bricks and tiles, and refractory materials.
