Abstract
Abstract Improved apparatus for mixing an oxygen containing gas with a vaporized, gasified or atomized hydrocarbon within the mixing chamber of a gas reforming device in which one or more tubes having discharge openings distributed over the flow cross section of the mixing zone supply the oxygen containing gas and further have attached thereto guide baffles which gradually enlarge the unobstructed flow cross section constricted by the tube or tubes.
