The structural composition of a shuttle kiln

Summary: Shuttle kiln: This is an intermittent firing kiln, similar in structure to a matchbox. The kiln car is pushed into the kiln for firing, and then pulled out in the opposite direction after firing to unload the fired ceramics. The kiln car is like a shuttle, hence the name shuttle kiln. Shuttle kilns are thermal equipment for intermittent production with a kiln car as the kiln bottom and a downdraft (or semi-downdraft) flame. They are also called car-bottom downdraft kilns, or drawer kilns because the kiln car enters and exits from one end of the kiln. They are one of the fastest-developing kiln types in China in recent ten years. In addition to the advantages of general downdraft kilns, such as great operational flexibility and the ability to meet multi-variety production, shuttle kilns allow loading, unloading, and partial cooling of the products to be carried out outside the kiln. This improves working conditions and shortens the kiln's turnover time. However, due to intermittent firing, the kiln has large heat storage and heat dissipation losses, high flue gas temperature, and high heat consumption. New energy-saving shuttle kilns have improved the kiln body masonry structure and added waste gas heat recovery devices, greatly improving this shortcoming.
