I disclose a conversion system for an exhaust duct or the like through which partially reacted gases are circulated, said system comprising a venturi induction member mounted in the exhaust duct and having a circumferential array of radially extending apertures for inducting a reactant fluid into said duct upon passage of said gases therethrough said venturi member having inlet and outlet openings each having substantially the same cross-sectional area as that of the adjacent interior of said duct, said apertures being located in a thickened portion of said venturi member and having a length-to-diameter ratio capable of imposing a jetting action upon the reactant fluid passing therethrough so that thorough mixing of said reactant fluid and said gases is attained within said venturi member. Also disclosed are unique venturi configurations involving a throat ridge and induction apertures adjacent thereto for improved induction and mixing.
