STEAM GENERATOR Russian patent published in 2019 - IPC F22B1/26 

FIELD: steam generators.

SUBSTANCE: use: for steam production. Summary of invention consists in the fact that nauger generator comprises a housing with a combustion chamber, a mixing head with fuel fuel supply cavities, fuel components supply belts connected to corresponding fuel components by means of channels, wherein fuel supply zones of fuel components are made in the form of several coaxially installed shells located each relative to each other with annular gaps, and forming closed annular cavities opening into combustion chamber, wherein annular cavities of fuel components uniformly alternate between each other, wherein in central part of head, between component feeding belts, there is a belt for supply of steam generating liquid, which cavity opens into combustion chamber cavity, at the ends of the shells on the side of the inlet there are end profiled bottoms fixed to each other and to the housing and forming in-series located annular cavities, wherein in the said bottoms and cavities there are insulated channels connecting said end cavities of supply of fuel components through one to each other, wherein the angular position of the channels in the previous cavity is different from the angular position of similar channels in the subsequent cavity, and the diameter of said channels decreases from the periphery to the center of the mixing head, wherein said annular cavities of fuel components are connected to corresponding cavities of supply of components through said end cavities formed by profiled bottoms.

EFFECT: technical result is possibility of steam generating liquid flow rate in wide range.
