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, at that, on the pipes surface there made are punching with height equal to the annular gap between the pipes, at that, the pipe outlet parts are attached to each other so that to form fuel and vapor generating liquid supply channels into the combustion chamber, wherein the first and second fuel components cavities alternate monotonously, at that, cavities for steam forming liquid supply are located in central and in peripheral parts of mixing head.

EFFECT: enabling improvement of mixture formation, reduction of overall dimensions, as well as elimination of non-uniformity of heating of shells.
