STEAM-GAS GENERATOR Russian patent published in 2017 - IPC F02C6/18 

FIELD: power industry.

SUBSTANCE: steam-gas generator comprises a fuel-cooled chamber, a mixing head which includes a housing, at the ends of which an upper and a lower bottoms are mounted, an intermediate bottom located between the housing and the head, an oxidizer manifold mounted on the housing, a fuel swirler located on the axis of the mixing head, spray swirlers located evenly around the circumference and including a hollow tip with screw channels and a sleeve covering the tip with an annular clearance and connecting the oxidizer cavity with the chamber cavity, wherein the axial channel of the tip connects the cavity of the ballasting component with the chamber cavity, and the fuel cavity is connected to the chamber cavity via tangential holes performed on the cylindrical surface of the fuel swirler, wherein the cavity of the chamber cooling path is connected with the fuel cavity of the mixing head.

EFFECT: invention allows to increase the uniformity of the temperature field of the vapour-gas mixture at the outlet in a wide range of temperatures and pressures due to the intensification of the evaporation process of the ballasting component.
