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 comprises housing with mixing elements installed therein for supply of fuel components and steam generating liquid, at that, 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 pipe outlet parts are interconnected to form fuel and vapor feed fluid supply channels to combustion chamber. At that first and second fuel components cavities alternate monotonously. At that steam-generating liquid supply cavity is located in central part of mixing head.

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