Separate Feedings Of Cooling And Dilution Air

The invention relates to separate feedings of cooling and dilution air. Concretely, the invention refers to a combustor arrangement of a gas turbine engine or power plant, comprising at least one combustion chamber, at least one mixer arrangement for admixing air or gas to the hot gas flow leaving the combustion chamber. The mixer arrangement is adapted to guide combustion gases in a hot gas flow path extend-ing downstream of the combustion chamber, wherein the mixer comprises a plurality of injection pipes pointing inwards from the side walls of the mixer arrangement for admixing air portions to cool at least the hot gas flow leaving combustion chamber. The mixer arrangement (200) is applied to at least one volume of dilution air (129) flowing from a first plenum and at least one volume of cooling air (110) flowing from a second plenum. 本发明涉及冷却和稀释空气的分开供给。具体而言，本发明涉及一种燃气涡轮发动机或发电站的燃烧器布置，包括至少一个燃烧室、用于将空气或气体掺合至离开燃烧室的热气流的至少一个混合器布置。混合器布置适于在热气流路径中引导燃烧气体，该热气流路径在燃烧室的下游延伸，其中，混合器包括从混合器布置的侧壁指向内的多个喷射管，以用于掺合空气部分来至少冷却离开燃烧室的热
