Double-stage radial cyclone of gas turbine combustor

The invention discloses a double-stage radial cyclone of a gas turbine combustor, and belongs to the technical field of gas turbines. The double-stage radial cyclone of the gas turbine combustor comprises a first-stage radial cyclone and a second-stage radial cyclone; each of the first-stage radial cyclone and the second-stage radial cyclone comprises one radial cyclone, a flow guide ring and a premixing cavity, wherein the flow guide rings and the premixing cavities are arranged at the downstream portions of airflows of the radial cyclones, each flow guide ring is located between the corresponding radial cyclone and the corresponding premixing cavity and communicates with the corresponding radial cyclone and the corresponding premixing cavity, and the bottoms of cyclone blades of the second-stage radial cyclone is connected with a circular end plate of the first-stage radial cyclone. By adopting the double-stage radial cyclone of the gas turbine combustor, the beneficial technical effects that stable combust
