What kind of heating tube is a radiation heating tube

Radiation heating tube is a type of radiative light wave heat transfer/electric heating tube that can transfer heat in multiple media. Heating medium is air: the efficiency of radiation electric heating tubes is higher than that of electronic tubes. The service life of radiation electric heating tubes is relatively lower than that of electric heating tubes. Radiation tube heating element, can be used for high temperature, medium and low temperature furnaces and special atmosphere furnaces. The outer pipe system adopts seamless high-temperature resistant alloy pipes, medium thick plate rolled pipes, centrifugal cast pipes, non-metallic special anti carburizing sleeves, etc., and ordinary resistance alloys cannot be used according to the heating elements of the radiation tube under various atmospheric and harsh cycling conditions.

Radiation heating tube is a heater used for separating the working chamber of a chemical heat treatment fuel furnace from the combustion gas. Radiation tubes are generally made of gas fuel and are cast or welded from heat-resistant steel. Radiation heating tubes come in various shapes, such as U-shaped, W-shaped, and trident shaped. The commonly used radiation tube is U-shaped. One end of the radiation heating tube is equipped with a fuel nozzle, and the other end is equipped with an injector for absorbing combustion products. The radiation tube heater started with the metal heat treatment process. Gas burns in radiation tubes made of heat-resistant alloy materials. Under a special atmosphere in the furnace, the workpiece is indirectly heated using the radiation heat generated by high-temperature alloy steel pipes. After heat treatment, the mechanical properties of the workpiece have been significantly improved. The application of radiant tube heaters in low-temperature heating or building heating is a new development in gas combustion technology in recent years. On the basis of the successful development of combustion safety and control technology, it has been widely used as an overhead radiation heating system abroad due to its simplicity, flexibility, and economy compared to traditional steam or hot water heating systems.
