MIXING HEAD OF SLOT-TYPE STEAM-GAS GENERATOR Russian patent published in 2019 - IPC F28D7/10 

FIELD: machine building.

SUBSTANCE: use: for mixing fuel components and steam generating liquid. Summary of invention consists in the fact that mixing head of slot-type steam-gas generator, comprising housing with installed in it mixing elements for supply of fuel components and steam forming liquid, characterized in that the housing is made consisting of several hollow shell rings with one bottom, successively installed one after another with formation of closed cavities for supply of fuel components and steam forming liquid, wherein said mixing elements are made in the form of several coaxially installed pipes of different diameter and different length, input parts of which are installed in hollow shell rings bottoms, wherein pipes of larger diameter and smaller length form peripheral part of each mixing element, and pipes of smaller diameter and longer length form its central part, wherein on the pipe surface there are straight longitudinal ribs, wherein the outlet parts of the pipes are attached to each other to form channels for supplying fuel components and steam generating liquid into the combustion chamber, wherein the first and second fuel components chambers are monotonously alternating between each other, wherein the steam generating liquid supply cavities are located in the central and in the peripheral parts of the mixing head.

EFFECT: improved mixture formation of fuel components, increased heat exchange area and protection of combustion chamber wall from high temperatures.
