A Shuttle Kiln is a car-bottom kiln with a door on one or both ends. Burners are positioned top and bottom on each side, creating a turbulent circular air flow. This type of kiln is generally a multi-car design and is used for processing whitewares, technical ceramics, and refractories in batches. Depending upon size and weight of ware, shuttle kilns may be equipped with car moving devices to transfer fired and unfired cars in and out of the kiln. Shuttle kilns can be either updraft or downdraft in design. A Shuttle Kiln derives its name from the fact that kiln cars can enter a shuttle kiln from either end of the kiln for processing, whereas a tunnel kiln has flow in only one direction.

Shuttle kilns, are also referred to as batch, periodic or intermittent kilns. These shuttle kilns use kiln cars to carry the product in and out of the kiln when the kiln is cool through one or 2 doors. Once loaded, the shuttle kiln is started and it goes up to top temperature and down again following a set cycle automatically. Burners and control zones are located to give uniform firing conditions to all of the product. At the end of the cycle the doors are opened and the kiln cars are removed. Often another set of kiln cars are loaded ready to put into the kiln and the process is repeated.

Verbindtech Machinery designs and fabricates shuttle kilns to meet your precise needs. Multi-kiln arrangements with automatic car handling systems are also available.

• Sizes: 1 m³ to 500 m³ (35 ft³ to 17,650 ft³)
• Temperature: up to 1,800°C (3,270°F)
• Insulation: fiber construction up to 1,600°C (2,900°F) and insulating brick up to 1,800°C (3,270°F)
• Fuel: natural gas, LPG, diesel, kerosene, other liquid fuels
• More flexible, so you only fire them when capacity dictates, compared to a continuous kiln
• Combustion System: Integrated Multi-Zone Pulsing System (IMPS^TM) or volume flow control
• Energy Recovery System: Preheated combustion air up to 425°C (800°F) or self-recuperative burners with preheated air up to 700°C (1,290°F)
• Lower initial capital cost, can be increased step by step
• Reduced space requirements
• Capable of firing different cycles, i.e. first fire and refire in same shuttle kiln
• Automated transfer cars and loading systems make automated handling possible
• Multiple kilns can be linked together with handling to achieve almost continuous production with additional flexibility
• Atmosphere control available
• Different firing modes available within firing cycles
