A combustor assembly having improved performance and improved pollution emission characteristics includes an annular combustion chamber and a premixing passageway having an outlet positioned adjacent either the inner or outer annular wall of the combustion chamber. The outlet is in gas communication with the combustion zone and has a perforated baffle thereacross. Air from the compressor enters the premixing passageway and atomizes fuel injected therein. The fuel-air mixture is directed from the premixing passageway through the perforated baffle radially across the combustion zone toward the opposite wall of the combustion chamber. The perforated baffle creates a localized stagnation region adjacent its surface which acts as a continuous ignition source for the combusting fuel-air mixture within the primary combustion zone. Additional air from the compressor is flowed to the combustion zone through openings in the inner and outer wall.
