  • Patent number: 4586328
    Abstract: A combustor for generating a hot gas stream by the combustion of fuel in a pressurized airstream is disclosed including a generally toroidal-shaped combustion chamber of relatively short axial length, an annular orifice providing for the entry of a main airstream into the combustion chamber and a premixing chamber for generating and directing a vapor phase air-fuel premixture into the entering main airstream to form a combustible mixture for burning in the combustion chamber. In a preferred form, the mixture burns along a generally toroidal-helical gas flow path. The combustor is particularly suited for use in a gas turbine engine.
    Type: Grant
    Filed: May 11, 1982
    Date of Patent: May 6, 1986
