HEAT EXCHANGE ELEMENT FOR INSTALLATION IN GAS FLOW HEATED BY MICROWAVE RADIATION ENERGY AND DEVICE FOR GAS MICROWAVE HEATING Russian patent published in 2021 - IPC F22G1/06 

FIELD: physics.

SUBSTANCE: invention relates to heating of gases in a flow, in particular for production of superheated steam by means of microwave radiation, and can be used, for example, for technologies using high-temperature gas, in particular overheated steam. Heat exchange element is made in form of body of porous material, capable of passing heated gas and absorb microwave radiation with release of heat, wherein in the central body part, an insert from a material which does not absorb microwave radiation is placed longitudinally relative to the gas flow. Heat exchange element is intended for use in device for microwave gas heating, which includes heat exchange part made in form of pipeline, having inlet for heated gas supply and outlet hole for heated gas removal, between which there is a heat exchange element shutting off the passage of the pipeline, and a microwave generating part configured to supply microwave radiation to the heat exchange element.

EFFECT: technical result is elimination of heat exchange element central part overheating, its melting and destruction.
