EVAPORATOR OF CRYOGENIC LIQUID Russian patent published in 2014 - IPC F17C9/02 

FIELD: heating.

SUBSTANCE: invention relates to the field of heat and power engineering and may be used to evaporate media in liquid state. An evaporator of cryogenic liquid comprises a body, in which there are heat exchange elements and a heater. The body is made in the form of two double-layer shells, forming a circular cavity for passage of heating coolant. Each shell comprises two rigidly joined shells, between which there are channels combined into headers for supply and drain of a cryogenic component. At the inlet to the circular cavity there is a cover, where mixing elements and an igniting device are installed. At the outlet there is a gas duct. Body shells comprise a cylindrical part and a narrowing conic part to form a circular cavity with channels for passage of the cryogenic component. Ribs that form channels for passage of the cryogenic component in the inner shell are made on the inner surface of the cylindrical part of the external shell, at the same time on the narrowing part of the shell the specified ribs are made on the outer surface of the internal narrowing part of the shell. Inside the conical part in its central zone there is a nozzle connected with the cavity of the internal shell. Headers for supply and drain of the cryogenic component into the inner cavity of the external shell are installed on the narrowing part of the external shell.

EFFECT: simplified design, reduced dimensions and weight.
