The kiln company talks about the firing technology of the kiln: the kiln is an essential equipment in the firing manufacturing industry. the perspective of the development history of ceramic firing, the firing methods of the kiln are divided into open flame and flame dew There are many methods such as burning and naked flame burning, and you must know too much about these burning techniques. Let's take a look at it together.
1. Burning method of Mingyan boxing
This type of firing method uses firewood coal as an energy source. The purpose of product packaging: First, to avoid the pollution of wood ash coal slag; second, to increase the loading capacity of the product. Because the products are put into the sagger first, and then assembled into a sagger column to be fired in the kiln, the product is directly heated, and a lot of energy is consumed on the kiln furniture. Therefore, the energy consumption of the sintering method of the open flame sifter is very high The temperature difference between inside and outside is large and the firing cycle is very long. This kind of firing method causes high product waste rate and low economic benefit, which has restricted the development of domestic ceramic industry for a long time.
2. Flame dew burning method
Ma fluoride kiln is a representative type of flame dew burning method. The flame dew burning method can partially solve the problem of temperature difference in the kiln, but because the product is still fired by the flame heating method, a large amount of energy is consumed on the thick refractory wall, and the flame kiln uses a small type , Can form a mass production batch.
3. Bright flame naked burning method
The naked flame method is a remarkable result of ceramic firing since the 1970s. The naked flame naked burning method as an advanced firing method has shown effects on the kiln temperature uniformity, kiln volume, production intensity and unit energy consumption. It has become a kiln type for modern building sanitary ceramic firing, so it can Popularize within a time. The open flame kiln temperature uniformity is high. This is because the product stack resistance of this firing method is small, the pressure in the kiln is reduced, and the negative pressure of the pre-heat belt is low, so there is little leakage of cold air.
According to the several kiln firing technologies introduced in the article, you can specifically understand that when using kiln equipment, you should choose the appropriate equipment according to its firing technology, so as to avoid problems such as reduced operating efficiency due to the wrong type selection
