Basic Knowledge of Kiln

Equipment built of refractory materials for calcining materials or products.
There are many types:
According to the type of calcined materials, it can be divided into ceramic kilns, cement kilns, glass kilns, enamel kilns, etc. The former can be divided into continuous kilns (tunnel kilns), semi continuous kilns, and intermittent kilns according to operation methods.
According to the pyrogen, it can be divided into flame kiln and electric kiln.
According to the heat source facing the green body, it can be divided into open flame kilns, flame isolated kilns, and semi flame isolated kilns.
According to the vehicle, it can be divided into kiln car kiln, push plate kiln, roller bottom kiln (roller kiln), conveyor belt kiln, walking beam kiln, air cushion kiln, etc.
According to the number of channels, it can be divided into single channel kilns, dual channel kilns, and multi channel kilns.
Generally, the fuel for large kilns is mostly heavy oil, light diesel oil, or gas, natural gas.
Kiln is usually composed of four parts: kiln chamber, combustion equipment, ventilation equipment, and conveying equipment.
Electric kilns mostly use electric furnace wires, silicon carbide rods, or molybdenum disilicide as heating elements. Its structure is relatively simple and easy to operate.
In addition, there are various atmosphere kilns, etc.
Whether the kiln structure is reasonable and the type selection is correct is directly related to product quality, output, and energy consumption. It is a key equipment in ceramic production.
