ABSTRACT:
A post-combustion device through which flows two concentric streams, one of which is a primary flow of air flowing into the internal stream and the other of which is a flow of secondary air flowing into the external stream. The device includes a plurality of flame stabilizing radial arms extending through the internal stream and a plurality of pivoting flaps, wherein the flaps assume a normal position when they separate the streams and a slanted position where they direct the flow of secondary air towards the primary flow. The flaps include a mechanism for pivoting the flaps on the arms and each flap extends between two adjacent arms. The flaps almost fully obstruct the external stream when in the slanted position.
