Tunnel kiln is a modern continuous firing thermal equipment, widely used in sanitary ware, tableware, color, material, building materials, cast stone and other products of high temperature, low temperature, flame element and glaze firing. Firing temperature 800-1500℃. The fuel can be natural gas, liquefied gas, gas, etc. Equipped with automatic programmable computer system, automatic carriage, high degree of automation, convenient and flexible loading and unloading, kiln furnace length is usually 30 to 120 meters, width is 1 to 3.3 meters. Can also be customized according to customer requirements.
Advantages of tunnel kiln:
1. Continuous production, short cycle, large output and high quality.
2. Using the countercurrent principle to work, so the heat efficiency is high, fuel economy, because the heat and the use of surplus heat are good, so the fuel is very economical.
3. Burn time reduced.
4. Labor saving, not only when the fire operation is simple, and the kiln and kiln out of the operation are carried out outside the kiln, it is also very convenient, improve the working conditions of the operators, reduce the labor intensity.
5. Improve the quality, pre-tropical, firing zone, cooling zone, three parts of the temperature, often maintain a certain range, easy to master the firing law, so the quality is better, the damage rate is also less.
6. The kiln and kiln furniture are durable, because the kiln is not affected by rapid cooling and rapid heating, so the kiln body has a long service life.
