An oxygen injector assembly for directing substantially pure oxygen into the path of an effluent or exhaust stream from a primary reformer process for mixing of the oxygen with the effluent, the assembly comprising an oxygen delivery tube for discharging the oxygen into the path of the effluent, and a cooling jacket disposed around the outer periphery of the delivery tube for moderation of the ambient temperature conditions surrounding the oxygen injector assembly and thus compensating for the increased temperature conditions created by the mixing of the oxygen with the effluent in lieu of mixing air therewith.

Oxygen injector means for secondary reformer

A duct burner apparatus and method for burning a gaseous fuel in the presence of a flowing oxygen-containing gas stream is provided. The apparatus comprises fuel gas supply means positioned in the path of the oxygen-containing gas stream and at least one elongated baffle means spaced from the conduit means on the downstream side thereof. The baffle means includes an inner wall portion and diverging outer wing portions and defines an ignition zone which is shielded from the conduit means. Spacer means for supporting the baffle means are attached thereto and to the conduit means, and fuel gas nozzle means are removably connected to the conduit means which extend to the baffle means for introducing fuel gas into the ignition zone and downstream thereof.
