STEAM GENERATOR Russian patent published in 2020 - IPC F22B1/02 

FIELD: power engineering.

SUBSTANCE: invention relates to power plants generating steam of high parameters obtained by energy released during combustion of hydrogen or natural gas (NG) in oxygen. Steam generator includes housing with combustion chamber, mixing head with fuel supply elements and fuel components supply belt, connected to corresponding cavities of components by means of channels. Fuel components supply belts are made in the form of several coaxially installed shells, arranged in relation to each other with annular gaps, and forming closed annular cavities opening into combustion chamber. End faces of the shell shells on the side of the inlet are equipped with end profiled bottoms fixed to each other and to the housing and forming in-series end annular cavities. In the above bottoms and chambers there are isolated channels connecting said end cavities of supply of fuel components through one to each other. Said annular cavities of fuel components are connected to corresponding fuel feed chambers via said end cavities formed by profiled bottoms.

EFFECT: proposed steam generator.
