Abstract
An assembly for a gas turbine engine includes at least one burner and a hydrogen manifold. The at least one burner includes an outer nozzle and an inner nozzle. The outer nozzle forms a combustion chamber. The outer nozzle includes an outer converging axial portion and an outer diverging axial portion. The outer converging axial portion is disposed at an upstream axial end of the outer nozzle. The outer diverging axial portion is disposed axially downstream of the outer converging axial portion. The inner nozzle includes an inner converging axial portion at a downstream axial end of the inner nozzle. The inner converging axial portion is disposed within the outer converging axial portion to form an annular gap between the outer converging axial portion and the inner converging axial portion. The hydrogen manifold is disposed at the upstream axial end. The hydrogen manifold is connected in fluid communication with the annular gap.
