Gasturbine and the combustor thereof

摘要

A gas turbine and the combustor thereof in which super high frequency combustion oscillation and the generation of NOx are reduced. The fluctuation in pressure which induces the fluctuation in heat liberation is suppressed in the gas turbine combustor comprising a plurality of main fuel supply nozzles (12a), each having a premixing nozzle (14) at the top end part thereof, by providing in the space upstream from the premixing nozzles partition elements (35) for dividing the space along the axis of the combustor or a honeycomb element having air passages in the axial direction, or by providing premixing nozzles composed of cylindrical elements with many holes (14a).
