ABSTRACT:
A combustor includes a pilot burner provided at a center portion thereof, and a premixer surrounding the pilot burner. The premixer has a plurality of premix chambers separated from one another in a peripheral direction. Each of the premix chambers includes a fuel injection nozzle provided at an inlet portion thereof, and a blade-like structural member disposed downstream of the fuel injection nozzle. Fuel and air, supplied from an inlet of the premixer, jointly form a premixture, and a Lanchester vortex is formed rearwardly of the blade-like structural member. The Lanchester vortex forms circulating flows at the outlet of the premixer, and also forms a main stream outside these circulating flows.
