W radiation tube improves heating efficiency

W radiation tube is a type of radiation tube that ensures the controllability of the atmosphere inside the furnace. Easy to control, install, and maintain temperature, easy to seal. Due to the absence of muffle cans in the furnace, the furnace capacity has been expanded, production capacity has been improved, heating and production efficiency have been improved, and materials have been saved. It is a good partner in the field of industrial processing. W-shaped radiation tubes have high thermal efficiency, but their wall temperature distribution and service life are worse than U-shaped radiation tubes. The P-type radiation tube is a type of exhaust gas recirculation. Because of its complex structure, manufacturing difficulty and less practical application, the O-shaped radiant tube has complex manufacturing, high cost, uneven surface temperature distribution, shorter service life than the U-shaped radiant tube, and less practical application. In fact, casing radiation tubes with waste heat recovery devices, casing radiation tubes with waste heat recovery devices, and U-shaped radiation tubes with waste heat recovery devices are the most widely used.

Development of W radiation tubes

1) In order to improve the heating efficiency of the radiation tube, the shape of the radiation tube can be designed as a three-dimensional curve or the surface area of the radiation tube can be increased.

2) The research on improving the thermal efficiency and surface temperature uniformity of radiation tubes has gone beyond the scope of radiation tubes and is developing towards higher-level metasystems.

3) The main research direction for improving the service life of radiation tubes is to improve the stress state of radiation tubes, and the main measure is to increase the flexibility of radiation tubes.

4) By analyzing and summarizing the main performance of radiation tubes based on the evolution theory of triz technology, it can be seen that the future development of radiation tubes will mainly follow the direction of metasystems. In order to improve the performance of the radiation tube, it is necessary to comprehensively consider the performance of each subsystem of the radiation tube and continuously introduce new subsystems. In addition, in order to improve the heating efficiency of the radiation tube, the main consideration should be to increase the surface area of the radiation tube. During the improvement process, the main focus was on studying the impact of changes in the geometric size of the radiation tube on the heating efficiency of the radiation tube. Therefore, the research and development of radiation tubes in these two directions will play an important role in improving the comprehensive performance of radiation tubes.
