FIELD: power engineering.SUBSTANCE: nozzle of a mixing head in a steam-gas generator comprises at least a hollow tip, which connects the oxidant's cavity with the combustion zone, a bushing that covers a tip with a circular gap and connecting the fuel cavity with the combustion zone, characterised by the fact that on the outer surface of the nozzle tip there are ribs arranged, which interact with their inner part with the inner surface of the bushing. The outer outlet part of the bushing is made as stepped, with increasing diameter of its outer surface. In the stepped expansion of the bushing there are channels that connect the cavity of the ballasting component, preferably water, with the combustion zone.EFFECT: invention makes it possible to increase homogeneity of temperature field of steam and gas mixture at the outlet in wide range of temperatures and pressures due to intensification of ballasting component evaporation process.13 cl, 25 dwg |
