1.Our tunnel kiln:
The tunnel kiln mainly includes four systems: kiln body, kiln conveying equipment, fuel burning system, and ventilation equipment.
a.Kiln body: The main part of the tunnel kiln system, with various airflow inlets and outlets on the kiln body.
b.Kiln conveyor equipment: kiln car and kiln furniture.
c.Fuel combustion system: including fuel delivery pipes, fuel preheating, burners, the heating and combustion of the tunnel kiln is mainly heavy oil, light diesel oil, and natural gas.
d.Ventilation equipment: including exhaust system, air curtain agitation system and cooling system. Its main function is to make the flow in a certain direction.
| Dimensions | Length:60-120m, Width: 2.0-3.5m |
| Daily output | 400,000~1,100,000 |
| Kiln material | Strict process with metal frame and refractory heat preservation material massonry |
| Metal frame | Welding of high quality shaped square tube steel and profiles. mosaic of baking varnish decoration steel plate, and with solid structure, looks nice. There have reserved 10mm expansion joint between each quarter of steel frame. Filled with asbestos packing. each section connects by bolt. kiln masonry is buider of high-grade lightweight refractory heat preservation material( partition select material, the material of the kiln lining choose the good thermal stability will be better, no easy to dirty). The high quality refractory materials are made of light mollies brick and so on. adopt the unique hanging form and choose the lightweight material, can effedively reduce the weight of kiln top and the heat storage, so that save energy consumption |
2.Tunnel kiln features
A.Continuous production, short cycle, large output and high quality.
B.The heat utilization is high, fuel economy, because the heat is maintained and the use of waste heat is very good, so the fuel is very economical, compared to the downdraft kiln can save fuel about 50-60%.
C. The firing time is shortened. It takes 3-5 days for the ordinary kiln to be installed from the kiln to the empty space, while the tunnel kiln can be completed in about 20 hours.
D. kiln and kiln furniture are durable. Because the kiln is not affected by the rapid cooling and rapid heat, the kiln has a long service life and is usually repaired once in 5-7 years.
