Low emission combustion chamber
Patent
·
OSTI ID:7267646
A low emission combustion chamber in which vitiated products of combustion from a pilot burner are caused to swirl about the combustion chamber axis before fuel droplets are introduced for flash vaporization is described. The resulting ignition lag lasts until swirling combustion air can be mixed with the swirling mixture to molecularly premix the fuel and air and increase its oxygen content to reduce autoignition at an equivalence ratio less than 1. The result is high-rate, lean burning in the primary combustion chamber.
