    摘要： A fuel mixture distribution system (35) for a turbine engine assembly (20) includes a combustor (26) that includes a wall (44) that defines a combustion chamber (46), a fuel mixture distributor that includes an air conduit (48) that defines a mixing chamber (52) that extends through the wall (44) along between an inlet (54) to an exit opening (56) to the combustion chamber (46), the air conduit shape is defined to achieve the desired mixing and prevent flashback at all operating conditions, and a fuel distributor (42; 58; 90; 98) extends into the mixing chamber (52) at a location upstream of the exit opening (56). The fuel distributor (42; 58; 90; 98) includes a plurality of fuel openings (68; 102; 112) where a fuel flow (38) is communicated and mixed with an airflow (40) passing through the mixing chamber (52).

    摘要： An injector (38) for introducing hydrogen and gas into a combustion chamber (40) of a gas turbine engine (20) includes a convergent-divergent nozzle head (42) and a hydrogen/gas feed nozzle (46). The convergent-divergent nozzle head (42) is arranged along a nozzle axis (A2) and has an upstream end defining an inlet mouth (44a). The hydrogen/gas feed nozzle (46) includes a mixing chamber (50) arranged along the nozzle axis (A2) upstream of the inlet mouth (44a), first feed conduits (52) configured to feed hydrogen into the mixing chamber (50), and second feed conduits (54) configured to feed gas into the mixing chamber (50). Each of the first feed conduits (52) and the second feed conduits (54) are tangentially oriented to the mixing chamber (50).

    摘要： An invention relates to devices for combustion of gaseous fuels, in particular to vortex burners. The technical result consists in simplification of the burner design, allowing to reduce the temperature of the inner surface of the flame tube and, thus, to eliminate the need for expensive thermal protection coating, as well as in improving the stabilization of the combustion process and implementation of the possibility of combustion at higher excess air factors (poor mixtures) due to the formation of a countercurrent vortex flow inside the flame tube. The burner with the two-layer vortex countercurrent flow contains a cylindrical burner body, a flame tube, and a nozzle coaxially installed therein, wherein an air duct is provided between the burner body and the flame tube; the flame tube contains a front wall having an inlet window and a rear wall having the nozzle; the burner body contains an inlet window fuel feeder, whereas the air duct at the inlet window contains a swirl nozzle, with an additional swirl nozzle and an additional fuel feeder located at the rear wall, and the nozzle is partially placed inside the flame tube.
