The invention refers to a combustor arrangement of a gas turbine engine or power plant, comprising at least one combustion chamber, and at least one mixer for admixing a dilution medium or air to the hot gas flow leaving the combustion chamber. The mixer is adapted to guide combustion gases in a hot gas flow path extending downstream of the combustion chamber, wherein the mixer comprises a plurality of injection pipes pointing inwards from the side walls of the mixer for admixing the dilution medium or air to cool the hot gas flow leaving combustion chamber. The mixer (115, 200, 222) comprising at least one dilution air plenum (111) having at least one pressure-controlled compartment (205-207; 209-211) which is directly or indirectly connected to at least one injection pipe (114a-c). 本发明涉及一种燃气涡轮发动机或发电厂的燃烧器布置，其包括至少一个燃烧室、用于将稀释介质或空气掺合至离开燃烧室的热气流的至少一个混合器。混合器适于在于燃烧室下游延伸的热气流路径中引导燃烧气体，其中混合器包括从混合器的侧壁指向内的多个喷射管，用于掺合稀释介质或空气以冷却离开燃烧室的热气流。混合器(115，200，222)包括具有至少一个压力受控的隔间(205-207；209-211)的至少一个稀释空气仓室(111)，该至少一个压力受控的隔间(205-207；
