Abstract (en)

[origin: EP3486570A1] A combustor of a gas turbine, including: a first-stage combustor and a second-stage combustor (13), arranged downstream of the first-stage combustor and including a second-stage combustion chamber (20) extending along an axial direction; an axial lance injector (16); and a flame stabilizer device (23). The axial lance injector (16) includes an elongated streamlined body (30) extending in the axial direction from the first-stage combustor into the second-stage combustion chamber (20) through a transition region (28) of the second-stage combustor (13). The elongated streamlined body (30) and the transition region (28) prevent gas recirculation in the transition region (28). First cross-flow injection nozzles (32) and second cross-flow injection nozzles (33) are provided on the elongated streamlined body (30) at respective axial locations and the flame stabilizer device (23) is arranged downstream of the first cross-flow injection nozzles (32) and of the second cross-flow injection nozzles (33).
