COUNTERCURRENT BURNER PRE-MIXING MODULE Russian patent published in 2021 - IPC F23D14/62 

FIELD: gas turbine engines.

SUBSTANCE: invention relates to devices designed for the formation and combustion of a fuel-air mixture in the combustion chambers of gas turbine engines. The countercurrent burner pre-mixing module contains an air supply channel, a pilot gas supply channel, gas outlet openings, and additionally contains a primary limited mixing chamber. The primary limited mixing chamber is profiled in the form of a diffusor-confusor channel. The primary limited mixing chamber is made reversible. The countercurrent burner pre-mixing module has a secondary direct-flow semi-limited mixing chamber with a fuel supply system distributed along its length.

EFFECT: invention provides ability to control the spatial position of the deflagration wave of the reaction and the implementation of the mechanisms of diffusion-kinetic combustion of fuel. It has a high degree of homogenization of the components of the fuel-air mixture, eliminates flame leakage and makes dynamic control of the combustion process possible.
