FIELD: power engineering.SUBSTANCE: method is proposed to produce steam in a steam gas generator comprising at least a chamber cooled with a ballasting component, a mixing head, comprising a unit of fuel components supply, a unit of ballasting component supply with a fire bottom, nozzles made of a hollow tip and a bushing, which covers the tip with a circular gap, installed in the specified units along concentric circumferences and connecting cavities of units with the combustion chamber cavity, at the same time on the outer surface of the nozzle tip there are ribs that interact by their external part with the inner surface of the bushing, and the outer outlet part of the bushing is made as stepped with increased diameter of its outer surface interacting with the fire bottom, at the same time in the stepped expansion of the bushing there are channels that connected the cavity of the ballasting component with the chamber cavity.EFFECT: increased homogeneity of temperature field of a steam and gas mixture at the outlet due to intensification of the process of ballasting component evaporation.14 cl, 27 dwg |
