Features of Tunnel Kiln
The section of tunnel kiln is similar to the cave of train, and it drives the kiln car slowly full of products on the track. Kiln cars are connected to each other, driven by the trolley, the direction of the kiln forward and the direction of the air flow in the kiln. The tunnel kiln is divided into preheating zone, firing zone and cooling zone with three components. The dried blank first enters the preheating zone and is preheated by receiving heat from the flue gas in the preheating zone and then enters into the firing zone. The fired product enters the cooling zone and the product passes the heat to the kiln. And the air heated by the product is extracted as a dry rough and heated air. The firing zone is provided with burners and combustion chambers at both ends. The fuel and combustion air are mixed and burned through the burner. The flue gas is discharged through the flue gas outlet on both sides of the preheating belt, the flue, the total flue and the smoke blower, and the chimney is discharged outdoors.
Tunnel kilns are equipped with exhaust system, air supply system and hot air circulation system. Its purpose is to make the kiln gas flow, accelerate the heat exchange of flue gas and products, the gas can flow in accordance with the provisions of the direction, so that the kiln has the required pressure system and atmosphere.
Kiln body structure must meet the requirements of firing process, firing process content: temperature curve, pressure curve, the atmosphere requirements, loading methods and loading density. They are based on abrasive calcination of physical and chemical changes, stress conditions and thermal mechanical properties of the development of the out. Kiln body structure must meet the technological requirements in order to produce high-quality products.
When the tunnel kiln is installed, it should follow the tightening and ensure that the gap is kept between the parts. So as to avoid the kiln due to hot air and the emergence of the temperature difference between the kiln temperature uniformity, and gas flow.
