What is a tunnel furnace?
kiln tunnel is a type of continuous furnace, which is usually open at both ends and warm centrally. Materials, such as bricks, can be browsed through the device in a continuous way, allowing large volume processing without turning off the furnace between the batch. The simplest tunnel furnace consists of a single source of heat in the middle of the device, while the materials slowly heat and then cool as they pass. More complicated versions can be sealed into the outer atmosphere, provide more heating and cooling phases and offer various internal atmospheric conditions. It can use a moving belt as a transport method via equipment, a truck system, a push plate or a number of other options. Regardless of a specific design, the subject of the device tends to process a large amount of material in a continuous manner.
For heating tunnel furnaces, a number of different methods can be used. Among the typical heat sources include electric heating elements and units with gas, with existing systems DUal heating. Some may also save energy by capturing heat at the cooling end and recirculation to help preliminary materials that enter the device.
Materials such as bricks, tiles and ceramics are some common products that can be produced in bulk using a tunnel furnace. Products, such as these, can also be burned using a intermittent furnace, even if it includes loading the device, sealing, and then unloading for each new dose. The kiln of the tunnel provides the advantage of a continuous process, so some materials begin to warm up at one end of the device, while others are fired in the middle and cool even more at the other end.
The more complex Kilns tunnel can be designed to process other types of materials that require specific environmental conditions. This can lead to a tunnel furnace that has fixed atmospheric and thermal specifications. Some rushRHY can include multiple temperature zones and atmosphere types into one unit. These highly regulated systems can be used to process things such as solar cells, oxygen sensors and rare soil elements. Electronic components, such as varistors, thermistors and capacitors, can also be processed, while other industries can create advanced ceramics or various phosphors.
