The Civic - A concept in vortex induced combustion for the solar Gemini 10 kW gas turbine
The development and qualifying of a 10 kW gas turbine generator set are discussed. The very small size of the gas turbine created problems and, in the combustor, novel solutions were necessary. Differing types of fuel injectors, combustion chambers, and flame stabilizing methods were investigated. The arrangement chosen had a rotating cap fuel injector, in a can combustor, with conventional swirl flame stabilization but was devoid of the usual jet stirred recirculation. The use of centrifugal force to control combustion conferred substantial benefit (Rayleigh instability criteria). Three types of combustion processes were identified: stratified and unstratified charge (diffusion flames) and premix. Emphasis is placed on five nondimensional groups (Richardson, Bagnold, Damkoehler, Mach, and Reynolds numbers) for the better control of these combustion processes.
