Technical Field

[0001] The utility model relates to the technical field of energy-saving kilns, in particular to an energy-saving kiln. Background Art

[0002] A kiln is a furnace used to burn ceramics, glass and other objects. It is usually built with bricks and stones and can be made into various sizes according to needs. Its heating materials include various energy sources such as combustible gas, oil or electricity. Compared with combustion kilns, electric kilns have higher energy utilization rates, lower pollution emissions and are more energy-efficient overall.

[0003] After searching, it was found that some existing kilns usually directly open the kiln door to dissipate heat to achieve the cooling result when cooling down. However, the rapid drop in temperature will cause cracks in fired ceramics, glass and other objects, and the excess heat cannot be recycled, which is not conducive to practical application and operation. In response to the above problems, we have launched an energy-saving kiln. Utility Model Content
