STEAM-GAS GENERATOR Russian patent published in 2018 - IPC F02C6/00 

FIELD: energy; technological processes.

SUBSTANCE: invention relates to power plants intended for generating steam-gas mixtures. Steam-gas generator contains a chamber cooled by a ballasting component, a mixing head including a housing, on the ends of which the top and bottom bottoms are fixed. And in the lower bottom are made mixing chambers, evenly distributed along the circumference. Steam-gas generator also comprises an intermediate bottom located between the housing and the bottom, a fuel manifold mounted on the housing, and injectors installed in the mixing chambers. In this case, the nozzles consist of a hollow tip that connects the oxidant cavity with the mixing chamber, a sleeve that surrounds the tip with an annular gap and connects the fuel chamber with the mixing chamber. Also, in the outlet part of the bushing there are grooves connecting the cavity of the ballasting component with the mixing chamber, the cavity of the cooling path of the chamber being connected to the cavity of the ballasting component of the mixing head. In the embodiment, a conical deflector is located in the outlet part of the mixing chamber.

EFFECT: invention makes it possible to reduce the overall dimensions and mass of the steam-gas generator, and also makes it possible to increase the uniformity of the temperature field of the steam-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.
