An oxy-fuel burner for producing a generally flat luminous flame, the burner having fuel passage terminating in a nozzle, the fuel passage and nozzle having a generally elongated cross-section, a housing of complementary shape surrounding the fuel passage, so that when fuel is introduced into the fuel passage and an oxidizer is introduced into the passage defined by a space between the housing and the fuel passage a generally flat luminous flame is produced at the nozzle end of the fuel conduit. A precombustor having a cross-sectional shape complementary to that of flame end of the burner can be disposed on the flame end of the burner housing to further enhance combustion and protect the burner from the furnace atmosphere.

An oxy-fuel burner for producing a generally flat luminous flame comprising in combination: a housing having a first end and a flame end said housing having a cross-sectional shape with a width and height of different dimension; a fuel conduit having a first end and a nozzle end disposed in spaced relation to and generally concentrically within said housing said fuel conduit having a cross-sectional shape complementary to that of said housing thus defining a passage between said fuel conduit and said housing, said fuel nozzle having a width to height ratio of between 2 and 60, said nozzle end of said fuel conduit and said flame end of said housing adapted for positioning relative to each other along a longitudial axis of said housing; and means to introduce fuel into said fuel conduit and an oxidizer into said passage between said fuel conduit and said housing, whereby a flame having a fuel rich core surrounded by an oxygen rich sheath is produced at the nozzle end of said fuel conduit.
