Abstract:
An improved processing apparatus, comprising a burner part and a separate processing part extending and interconnected substantially rectilinearly so that said burner part discharges into said processing part, said burner part comprising an elongate gas flow conduit having an open inflow end and an open outflow end which is arranged to discharge gas into said processing part and said processing part comprising a gas flow conduit having an open inflow end; an annular flow manifold for an input gas adjacent to and surrounding an outflow end portion of said gas flow conduit of the burner part, said annular flow manifold and said gas flow conduit of the burner part defining with said open inflow end of the gas flow conduit of the processing part and therebetween a single, continuous, annular slot at said open inflow end of said gas flow conduit of said processing part for discharge of said input gas into flow of gas discharging into said processing part from said outflow end of said gas flow conduit of said burner part, said slot being the sole flow communication between said manifold and said gas flow conduit of said processing part and constituting spacing between said outflow end of said gas flow conduit of the burner part and said open inflow end of the gas flow conduit of said processing part; structural means securing said burner part and said processing part together at, but outside of, said slot substantially without inhibiting flow of gas through said slot, whereby a substantially continuous, annular curtain of said inflow gas is directed into said flow of gas passing from said gas flow conduit of said burner part into said gas flow conduit of said processing part; means for flowing gas into the inflow end of said gas flow conduit of the burner part; means for flowing an input gas into said annular flow manifold; means for flowing a fuel gas into said gas flow conduit of the burner part; and means for igniting the flowing gas passing from said gas flow conduit of said burner part into said gas flow conduit of said processing part for burning within said processing part of the apparatus.
