STEAM-GAS GENERATOR Russian patent published in 2017 - IPC F22B1/22 F23D11/36 

FIELD: power industry.

SUBSTANCE: steam-gas generator contains cooled ballasting component chamber, the mixing head comprising a housing, the ends of which are secured upper and lower bottom, an intermediate bottom arranged between the housing and the bottom head, oxidant manifold mounted on the casing and nozzles evenly spaced around the circumference. The nozzles consist of an axial duct, made dull by its front part connected by means of tangential holes disposed uniformly circumferentially cavity fuel annular channel with tangential openings spaced evenly around the circumference and opening into the cavity of the oxidizer, located coaxially to the axial channel pre-chamber, which is a continuation of the annular channel, communicating with one side of the annular channel and an axial channel, and on the other hand - the steam-gas generator chamber with the cavity. At around the end of the nozzle pre-chamber provided with holes connecting the cavity of the ballasting components, preferably water, steam-gas generator chamber with the cavity. Hollow chamber regenerative cooling path is connected with the cavity ballasting components.

EFFECT: reduction in size and weight of steam-gas generator, temperature field uniformity increase in combined cycle sweep the output over a wide range of temperatures and pressures due to the intensification of the process of evaporation ballasting component.
