Industrial Tunnel Kiln Brick Ceramics Sintering Drying Tunnel Kiln
Product Description:
Tunnel kiln is tunnel-like kiln built with refractory materials, thermal insulation materials and building materials, equipped with kiln cars and other vehicles. It is a modern continuous firing thermal equipment.The tunnel kiln is widely used in the roasting production of ceramic products and is also used in metallurgical industries such as abrasives.
Working Principle:
Tunnel kiln is long straight tunnel with fixed walls and vaults on both sides and the top, and a kiln car running on the track laid at the bottom. The combustion equipment located on both sides of the middle of the tunnel kiln, forming a fixed high-temperature zone - the firing zone. The high-temperature flue gas generated by the combustion flows along the tunnel to the kiln head under the action of the chimney or induced draft fan at the front end of the tunnel kiln, and gradually preheats the products entering the kiln. Cold air is blown into the kiln tail of the tunnel kiln to cool the products in the last section of the tunnel kiln. After the blown cold air flows through the products and is heated, it is extracted and sent to the dryer as a heat source for drying the green body. This section constitutes the cooling zone of the tunnel kiln.
The sagger filled with ceramic products is placed on the trolley and is slowly pushed in from the entrance of the preheating zone continuously, while the trolley carrying the fired products is gradually pushed out from the outlet of the cooling zone.
Features:
1. Tunnel kiln production is continuous, with short cycle, large output and high quality.
2. Tunnel kiln works on the countercurrent principle, with high heat utilization rate and fuel economy
3. Save labor. Improve the working conditions of operators and reduce labor intensity.
4. Improve quality. The temperatures of the preheating zone, firing zone and cooling zone are often kept within a certain range, making it easy to master the firing rules, so the quality is better and the breakage rate is less.
5. The kiln and kiln tools are durable. Because the kiln is not affected by rapid cooling and heating, the kiln body has a long service life
