DYNAMICALLY-SEPARATED CAN-TYPE COMBUSTOR

Title:

DYNAMICALLY-SEPARATED CAN-TYPE COMBUSTOR

Document Type and Number:

Japanese Patent JP2004116992

Kind Code:

A

Abstract:

To provide a can-type combustor capable of improving combustor performance by decreasing or removing a dynamic response of a push-pull mode, and to decrease a fatigue damage corresponding thereto.

Each combustion gas flow (24) is generated in this can-type combustor (18). The flow is introduced into a circular turbine nozzle (26) in the downstream direction. Dynamic interaction of the combustion gas flow adjacent in the circumferential direction is suppressed between a can and the nozzle in the axial direction. Blades (48) form a plenum (60) extending in the circumferential direction, and block a cross flow in the circumferential direction of an adjacent flow in the plenum by being segmented in the circumferential direction by a corresponding baffle (62) extending from an adjacent transfer part (44) to the front edge (54) corresponding to the blades (48) in the axial direction downstream direction.
