An electromagnetic induction heating device for obtaining high-temperature rare gas

Abstract

An electromagnetic induction heating device for obtaining high-temperature rare gas, including metal heating tubes, electromagnetic induction coils, electromagnetic induction heating power supplies, flanges, gaskets, containment cylinders, heat insulation layers, refractory filling materials, inlet and outlet pipes, and cover plates , Graphite filler; rare gas enters the metal heating tube from the inlet pipe, and under the action of induction electric heating, the metal heating tube is heated to a high temperature state, thereby heating the rare gas inside, and then the high-temperature rare gas flows out from the outlet pipe; the containment shell The body is an inert gas atmosphere to prevent oxidation of the metal heating tube at high temperatures; the containment shell is made of high-temperature resistant materials to ensure that the temperature of each component of the heating device is lower than the corresponding temperature limit; the entire heating device is connected by a flange to avoid The shortcomings of the high-temperature-resistant special materials used in the metal heating tube are not easy to weld; the heating device can heat the gas to a higher temperature, and can run safely and stably for a long time, while meeting the current processing technology requirements.

Description

technical field [0001] The invention relates to the technical field of ultra-high temperature gas reactor thermal hydraulics, in particular to an electromagnetic induction heating device for obtaining high-temperature rare gas. Background technique [0002] The high-temperature gas-cooled reactor is one of the mainstream reactor types of the fourth-generation nuclear reactor, which uses high-temperature gas as the cooling medium and graphite as the moderator.

The Shidao Bay high temperature gas-coo...

AI Technical Summary

Problems solved by technology

However, the current heating device for high-temperature gas has great deficiencies and is difficult to realize, which is mainly affected by the high-temperature resistance of the material.

The processing and welding performance of high-temperature-resistant special metals is worse than that of conventional metal materials, which leads to strict restrictions on processing and assembly during its application

Conventional gas heating methods and scheme designs are difficult to directly extend to the application of high temperature gas heating
