MIXING HEAD OF SLOT-TYPE STEAM-GAS GENERATOR Russian patent published in 2020 - IPC F28D7/10 

FIELD: machine building.

SUBSTANCE: use: for supply of fuel components and steam forming liquid. Summary of invention consists in the fact that mixing head of slot-type steam-gas generator includes housing with installed in it mixing elements for supply of fuel components and steam forming liquid, wherein housing is made consisting of several hollow shells 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 shells 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 surface of the pipes there are helical ribs, wherein the direction of the ribs on each subsequent tube is different from the direction of the said ribs on the previous pipe, at that, the pipe outlet parts are fixed to each other with the fuel channels and steam-generating liquid supply channels 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: enabling improvement of mixture formation, reduction of overall dimensions, as well as elimination of non-uniformity of heating of shells.
