DEVICE FOR PRE-HEATING OF MIXTURE FROM HOT GAS, IN PARTICULAR, NATURAL GAS, AND OXYGEN Russian patent published in 2013 - IPC F23D14/66 F23C13/02 F23D14/64 

FIELD: power engineering.

SUBSTANCE: device for continuous pre-heating of a mixture from a combustible gas, in particular, natural gas, and oxygen, prior to its catalytic burning, combustion heat of which provides for the possibility to heat gas extracted from a depot prior to its expansion or after its expansion in order to compensate for Joule-Thomson effect and supply to loads. The device is made in the form of a jet pump with a pump nozzle (3) and a receiving nozzle (7) arranged coaxially with it, the pump nozzle (3) is an inlet for a mixture arranged in the body (4) of the pump of the mixing chamber (5), with the mixing chamber (5) there is a suction pipeline (6) connected for natural gas heated with the help of catalytic burning, the receiving nozzle (7) is a part of the outlet of the mixing chamber (5) of the jet pump, the pump nozzle (3) and the receiving nozzle (7) are arranged as capable of displacement relative to each other in the body (4) of the pump, besides, the device has a control mechanism for adjustment of the distance between the pump nozzle (3) and the receiving nozzle (7) depending on temperature of gas mixture flow, outgoing from the outlet of the mixing chamber.

EFFECT: invention makes it possible to increase stability of the process of catalytic reaction of oxygen and natural gas.
