CRYOGENIC LIQUID EVAPORATOR Russian patent published in 2017 - IPC F17C9/02 

FIELD: heating.

SUBSTANCE: cryogenic liquid evaporator contains the combustion chamber cooled by a cryogenic liquid, a mixing head including a fuel supply unit, an oxidant supply unit, fire bottom unit, wherein the nozzles are installed in the mentioned units along the concentric circles, consisting of a hollow tip and the sleeve, enclosing the tip with the annular gap. There are ribs on the outer surface of the nozzle tip, interacting by its outer part with the inner surface of the sleeve, wherein the heat exchange elements are disposed in the inner cavity of the combustion chamber made in the form of Field's tubes, which outer tube inlet and inner tube outlet is connected to the fire bottom unit cavities. One of its cavities communicates with the combustion chamber cooling channel, and the gas duct is installed in the outlet part of the combustion chamber, in the embodiment, the ribs formed on the outer surface of the mixing head nozzle tip, are positioned at the angle to the longitudinal axis of the nozzle, the mixing head nozzle tip from the oxidant supply side is made blind. The tangential holes are made at its outer surface, which are equally spaced around the circle and communicating with the oxidant cavity.

EFFECT: using of invention allows to expand the evaporator functionality and improve its performance.
