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

FIELD: machine building.

SUBSTANCE: use: for steam production. Summary of invention consists in the fact that steam generator comprises a housing with a combustion chamber, mixing head with fuel components supply cavities, fuel components supply belts, connected to corresponding fuel components cavities 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 end 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 end annular cavities, wherein the said cavities length is reduced from the inlet part of the combustion chamber to the output one, at that in the bottoms and bottoms there are insulated channels connecting said end cavities of fuel components supply through one to each other, 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: enabling possibility of steam forming fluid flow rate in wide range.
