Advantages of Tunnel Kiln
Tunnel kiln has a number of advantages.
1, Continuous production, short production cycle, high yield, high quality.
2, It adopts countercurrent principle, and therefore high thermal efficiency, fuel economy, because the use of heat and waste heat to maintain very good, so it saves fuel.
3, the firing time is shorter, common large kiln from the kiln to the loading space require about 3-5 days, but the tunnel kiln is about 20 hours to complete.
4, Save labor. The firing operation is simple, loaded kiln and kiln operations are carried out in the kiln. So it is also very convenient, improve the working conditions of the operator, and reducthe labor intensity.
5,Improve quality. The temperature of three parts, Preheating zone, firing zone and cooling zone often maintain a certain range, it is easy to grasp its firing rules, so the quality is also good with less breakage.
6, Kilns and kiln furniture are durable. Because the kiln from thermal shock of the impact, so the kiln has long life, usually 5--7 years to repair once.
However, the construction of tunnel kiln meeds more materials and equipment, so the investment is large. Due to the continuous firing kiln, the firing system should not arbitrarily change, generally only apply to the production and firing system, which requires essentially the same products in large quantities with les flexibility.
