ABSTRACT:
An apparatus for placement in the effluent path of the combustible gases created by fuel burning in a combustion chamber and delivering such combustible gases to a catalyst is disclosed. A finned holder for placement downstream of the burning fuel is provided. The fins on the holder serve to create turbulence in the combustible gases emanating from the burning fuel. The holder also serves to support a secondary air introduction ring. The ring uniformly introduces preheated secondary air to the combustible gases through a plurality of ports in the ring thus forming a substantially homogeneous mixture of gases. The homogeneous mixture of gases is delivered to a catalyst located above and downstream of both the holder and ring.
