Abstract

A gas turbine combustor comprising a pilot nozzle (12) arranged on a central axis of said combustor and a plurality of pre-mixing nozzles (11) arranged around the pilot nozzle (12). A diameter of a combustion zone of the combustor is set such that, where an area is taken on a radial directional plane of the combustor, the area inside of the combustion zone and outside of a pitch circle (P) that is defined as a circle on which all central axes of the plurality of pre-mixing nozzles (11) are arranged, less the area taken by the plurality of pre-mixing nozzles (11) outside of the pitch circle (P), is a half or more of the area of all of the plurality of pre-mixing nozzles (11). With this structure, the flame holding ability of the combustor can be enhanced, the pilot fuel quantity can be reduced and a very low NOx generation can be realized.
