<p>Apparatus is disclosed for aerodynamically varying the fuel/air ratio delivered to a primary combustion zone of a combustor, said apparatus including a snout assembly defining an inlet passage for receiving pressurized air and delivering same to the inlet of a carbureting apparatus. One wall of the inlet passage includes an exhaust manifold, actuation of which serves to divert the flow of pressurized air away from the opposite wall and thereby vary the amount of air entering the carbureting apparatus. The exhaust manifold may be replaced by a ventilating manifold and step which utilize the Coanda effect for the same purpose.</p> |
