STEAM GENERATOR Russian patent published in 2020 - IPC F22B1/00 

FIELD: electricity.

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 cavities of fuel components supply and fuel supply zones, connected to corresponding cavities of components by means of channels. Belts of fuel components supply are made in the form of several coaxially installed shell rings located in relation to each other with annular gaps and forming closed annular cavities opening into combustion chamber. Annular cavities of fuel components uniformly alternate. In the central part of the head, between the components supply belts, there is a belt for supply of the steam generating liquid, the cavity of which opens into the cavity of the combustion chamber. End faces of the shell shells on the side of the inlet are provided 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: this invention allows to simplify steam generator design, as well as possibility of steam flow rate control.
