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

FIELD: machine building.

SUBSTANCE: invention can be used for mixing of fuel components and steam forming liquid. Essence of the invention consists in the fact that the mixing head of the slot-type steam-gas generator comprises a housing with installed in it mixing elements for supply of fuel components and steam-forming liquid, at that, 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, 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: improved mixture formation of fuel components, increased heat exchange area and protection of combustion chamber wall from high temperatures.
