摘要： A trapped vortex combustor for gas turbine engines. An annular combustor housing is provided having a plurality of inlet centerbodies disposed along a helical axis. The inlet centerbodies include a leading edge structure, opposing sidewalls, a pressurizable cavity, and a rear wall. Inlet centerbodies cooperate with adjacent structure and an aft bluff body to define a trapped vortex cavity combustion chamber for mixing an inlet fluid and burning fuel to form hot combustion gases. Mixing is enhanced by utilizing struts adjacent to the rear wall to create eddies in the fluid flow, and by injecting fuel and/or air in opposition to swirl created by the bulk fluid flow. Hot combustion gases are utilized in a turbine for extraction of kinetic energy, or in heat exchange equipment for recovery of thermal energy. High combustion efficiencies and less than 10 ppm emissions of oxides of nitrogen and of carbon monoxide are achieved.
摘要翻译：用于燃气涡轮发动机的被捕获的涡流燃烧器。提供了具有多个沿螺旋轴设置的入口中心体的环形燃烧器壳体。入口中心体包括前缘结构，相对侧壁，可加压空腔和后壁。入口中心体与相邻结构和后悬流体配合以限定用于混合入口流体和燃烧燃料以形成热燃烧气体的被捕获的涡流腔燃烧室。通过利用靠近后壁的支柱来增强混合，以在流体流动中产生涡流，并且通过喷射燃料和/或空气来抵抗由主体流体流产生的漩涡。热燃气体用于涡轮机中用于提取动能，或在用于回收热能的热交换设备中使用。实现了高燃烧效率和小于10ppm氮氧化物和一氧化碳的排放。
