There are many types of ceramic kilns, and batch kilns can be divided into direct flame kilns, flat flame kilns, and inverted flame kilns according to the flow direction of the flame in the kiln. Continuous kilns include tunnel kilns, roller kilns and push plate kilns. Rapid firing batch kilns include shuttle kilns and cap kilns.
Chinese ceramic kilns have a long history. Famous traditional kilns mainly include Jingdezhen kiln, dragon kiln and class kiln. Jingdezhen kiln is one of the most famous ceramic kilns in China, with a long history, having been used as early as the Tang Dynasty. The characteristics of Jingdezhen kiln are that it is fired with firewood, the temperature is high, and the firing time is long, so the ceramics fired are of excellent quality and have a wide variety. It is mainly based on firing celadon, white porcelain, colored porcelain, etc., and is known as the "porcelain capital".
The dragon kiln is a type of ancient Chinese ceramic kiln, named because of its resemblance to a dragon. The building structure of the dragon kiln is simple, built with earth and stone, and the length can reach tens of meters. The firing temperature of the dragon kiln is high, and the quality of the fired ceramics is better. In ancient times, the dragon kiln was the main ceramic production equipment in the southern region.
The class kiln is a relatively modern ceramic kiln, which has a complex architectural structure and consists of multiple kiln chambers. Each kiln chamber has a different temperature and atmosphere, and many different types of ceramics can be fired at the same time. The advantages of the class kiln are its high firing efficiency, high energy utilization rate, and good environmental performance.
In addition to these three main traditional kilns, there are many other types of ceramic kilns in China, such as cylinder kilns, steamed bread kilns, tunnel kilns, etc. Each of these kilns has its own characteristics and has played an important role in different historical periods and geographical scopes.
At present, China's daily ceramic industry widely uses tunnel kilns, roller kilns and push plate kilns, and retains a small number of inverted flame kilns for production. With the development of science and technology and the change of people's lifestyle, the traditional ceramic kiln has been gradually replaced by modern production methods. However, although these modern production methods have improved production efficiency and product quality, there are also some environmental problems and waste of resources. Therefore, in order to solve these problems, many ceramic enterprises have begun to explore more environmentally friendly and sustainable production methods.
Among them, a new type of ceramic kiln - gas kiln has gradually attracted attention. The gas kiln uses gas as fuel, which has the advantages of high efficiency, environmental protection and energy saving. Compared with traditional coal kilns, gas kilns can greatly reduce the emission of exhaust gas and dust, and reduce environmental pollution. At the same time, the gas combustion temperature of the gas kiln can reach more than 1300, which ensures the firing quality of ceramic products.
In addition, some ceramic companies have also begun to try to use electric kilns. Electric kilns use electric energy as an energy source, which is not only environmentally friendly, but also has high energy utilization. At the same time, the firing temperature of the electric kiln can reach more than 1400 meters, which can meet the firing requirements of various ceramic products.
These new ceramic kilns not only meet the environmental protection requirements of modern society, but also bring more economic benefits to enterprises. With people's increasing attention to environmental protection and sustainable development, these new ceramic kilns will become the development trend of the ceramic industry in the future.
