Structural classification of tunnel kilns

Tunnel kiln is a continuously working thermal processing equipment, which is widely used in sintering bricks and tiles, ceramics and refractory materials, new materials and other industries. Its unique design and operation mode make it have significant advantages in improving energy efficiency, ensuring product quality and improving production efficiency.

(1) Single-channel linear type: This is the most commonly used basic structural form in sintered brick and tile factories. The structure is simple and easy to operate, suitable for small and medium-sized production lines.

(2) Multi-channel parallel linear type: By arranging multiple channels in parallel, the processing volume of products per unit time is increased, which is suitable for large-scale continuous production and has higher thermal energy utilization rate.

(3) Single-channel multi-jointed linear type: This is an innovative design that combines space optimization and energy-saving concepts, and can increase production capacity without increasing the floor space.

(4) "One-stop" linear type (baking kiln and drying kiln combined) Integrate the drying and baking processes into one, effectively recycle and utilize waste heat, and greatly improve the overall energy efficiency.

(5) Other kiln types: Circular mobile tunnel kiln, shuttle kiln, roller kiln, push plate kiln. These kiln types usually do not use kiln cars. They are suitable for specific products or process requirements and have a higher degree of automation and temperature control accuracy.

Except for the circular mobile tunnel kiln, roller kiln and push-plate kiln, the other linear tunnel kilns all require a kiln car to carry the products and move along the length of the kiln body to complete the entire firing process.
