Method and device for heating a gas by the Joule effect

摘要

Method consisting in passing through a succession of flat perforated heating elements, heated by the Joule effect, the flow of gas to be heated, perpendicular to the surface of the said heating elements. The device for implementation is formed by an enclosure 2 comprising internally a thermal insulator 3, heating elements 40... 43... perpendicular to the axis of the enclosure and each supplied with an electrical current with an identical power or with a power which decreases from the heating element at the input end as far as the heating element at the output end. <IMAGE>
