What are the components of radiant heating tubes?

Radiant tube is a kind of equipment for industrial furnaces, which plays an important role in the operation of industrial furnaces. Outsiders may know little about radiant tubes. Today, let's learn about the composition and functions of radiant tubes. Radiant tubes have the advantages of stable electrical performance, high thermal efficiency, fast heating, small thermal hysteresis, high heat transfer and thermal energy utilization, and installation, detection and maintenance are all carried out outside the furnace, without stopping the furnace or cooling the furnace temperature for maintenance and replacement of electric heating devices. Therefore, it will be used both in industry and in some civilian equipment.

The utility model is mainly composed of a radiant tube body, a heat exchanger, a burner, etc. The radiant tube body is a key component for radiating the heat energy released by fuel combustion to the strip. Among them, U-shaped radiant tubes with waste heat recovery devices are widely used in horizontal heat treatment furnaces, and the heat exchanger is one of the two core components of the radiant tube heating device.

Its main function is to improve the overall service life of the radiant tube. The temperature needs to reach the highest possible preheating temperature and the lowest possible exhaust temperature, and reduce the resistance loss of the preheated air, thereby ensuring that the radiant tube will not be damaged by the environment, thus extending the service life of the radiant tube; and the burner is another core part of the two cores in the radiant tube heating device, which controls the power of the radiant tube heating.

Thermal efficiency, temperature distribution, master the life of the heat dissipation tube. With the development of today's industry, the requirements for related equipment are getting higher and higher, and the market demand for radiant tubes is also increasing. To improve the quality of radiant tubes, we must start with these components and ensure that the performance of the components is excellent in order to improve the performance of radiant tubes.
