Beschreibung
Zusammenfassung:	A gas turbine combustor comprising a combustor cylinder (3b,10) supported in a combustor (3) housing portion of a turbine casing (2), a pilot nozzle (8) arranged at the center of said combustor cylinder (3b,10), and a plurality of main nozzles (7) arranged around said pilot nozzle (8). A flow ring (20) having an annular shape with a semicircular section is mounted so as to cover an upstream end of said combustor cylinder (3b,10) with the semicircular section while keeping a predetermined gap therebetween. A porous plate (50) is arranged downstream of said flow ring (20) for closing a space which is formed in said combustor cylinder (3b,10) between said pilot nozzle (8) and said main nozzles (7). A guide portion (60) is disposed around an inlet portion of the combustor housing portion of said turbine casing (2), said guide portion (60) having a smoothly curved face for covering the whole circumference wall face of said inlet portion.
