    Experience The Advantages Of The Steel Belt Kiln Durability And Reduced Firing Time


    The tunnel kiln is designed as a long, linear tunnel with fixed walls and a roof, and tracks on the bottom where kiln cars move. Combustion devices are located at the middle sides, creating a high-temperature firing zone. The high-temperature gases flow towards the kiln entrance due to the chimney or fan at the front end, preheating the materials entering the kiln. This preheating zone is crucial for preparing the materials. At the kiln's end, cold air is introduced to cool the finished products, and this air is then heated by the products and used in the dryer for green body drying. This cooling section completes the tunnel kiln's structure.

    Kiln cars loaded with clay bodies are pushed continuously through the preheating zone, while fired products exit through the cooling zone.

    Advantages of Tunnel Kiln:

    1. Continuous production with a short cycle time, large output, and high quality.
    2. High thermal efficiency and fuel savings, with heat retention and residual heat utilization saving around 50-60% of fuel.
    3. Reduced firing time, needing about 20 hours compared to 3-5 days for traditional large kilns.
    4. Labor efficiency: Easy operation and external loading/unloading reduce labor intensity and improve working conditions.
    5. Enhanced quality: Consistent temperatures in preheating, firing, and cooling zones make it easier to control the process, resulting in better quality and fewer defects.
    6. Durability: The kiln structure is resistant to rapid temperature changes, extending the service life to 5-7 years before maintenance.

    However, building a tunnel kiln requires substantial materials and equipment, leading to higher initial costs. Being a continuous firing kiln, it is best suited for large-scale production of items with similar firing requirements, limiting operational flexibility.

    Tunnel kilns are suitable for firing blue bricks and tiles, ceramics, and new energy materials, with structures either built or assembled from steel.
