Abstract
A combustion air delivery system comprising a compressor operable to provide a stream of compressed air and a bypass duct positioned to divide the stream of compressed air into a bypass flow stream and a primary flow stream. A recuperator is operable to preheat the primary flow to produce a flow of preheated compressed air. A premix chamber receives the bypass flow stream and mixes the bypass flow stream with a flow of fuel to produce a fuel-air flow. A can member at least partially defines a primary zone that receives the fuel-air flow and includes an aperture sized to admit a predetermined portion of the flow of preheated compressed air. The fuel-air flow and predetermined portion of the flow of preheated compressed air mix in the primary zone to produce a combustible flow. An igniter is operable to ignite the combustible flow.
