Can-annular turbine combustors comprising swirler assembly and base plate arrangements, and combinations
Abstract:
A gas turbine combustor (10) comprises a main swirler assembly (400) comprising an annulus casting (410) itself comprising a modified downstream end (418) fitted into an reversed-edge base plate (450) that comprises an opening (453) defined by a lip (452) oriented upstream. The lip (452) comprises an upstream surface (457), an outboard surface (458) and an inboard surface (459). In certain embodiments the modified downstream end (418) has a shape to fit against the upstream surface (457) and the outboard surface (458) so as to increase the natural frequency of the main swirler assembly (400) to above the natural frequency of the combustion in the gas turbine combustor (10).
Abstract(Chinese):

燃气涡轮机燃烧器（10）包括主旋流器组件（400），主旋流器组件（400）包括环形铸件（410），其包括装配到反向边缘基板（450）中的改进的下游端（418），所述改进的下游端（418）包括限定的开口（453） 通过面向上游的唇缘（452）。 唇缘（452）包括上游表面（457），外侧表面（458）和内侧表面（459）。 在某些实施例中，改进的下游端（418）具有适合抵靠上游表面（457）和外侧表面（458）的形状，以便将主旋流器组件（400）的固有频率增加到高于固有频率 燃气轮机燃烧器（10）中的燃烧。
