Title: BURNER ASSEMBLY, COMBUSTOR, AND GAS TURBINE
Abstract:
This burner assembly of a combustor is equipped with: a plurality of first nozzles arranged in the circumferential direction of the combustor; a plurality of first burner cylinders which accommodate the plurality of first nozzles; and intermediate flow path forming portions which are connected to the downstream ends of the plurality of first burner cylinders so as to form intermediate flow paths allowing communication between the interior space of the plurality of first burner cylinders and the combustion chamber of the combustor. The intermediate flow path forming portions each have an inner peripheral wall which is positioned radially around the inside of the combustor such that the distance thereto from the center axis of the combustor is unequal in the circumferential direction.
