Oxy-fuel burner

摘要

An oxy-fuel burner (10) for producing a generally flat luminous flame, the burner having fuel passage (12) terminating in a nozzle (16), the fuel passage (12) and nozzle (16) having a generally elongate cross-section, a housing (18) of complementary shape surrounding the fuel passage (12), so that when fuel is introduced into the fuel passage (12) and an oxidizer is introduced into the passage defined by a space between the housing (18) and the fuel passage (12) a generally flat luminous flame is produced at the nozzle (16). A precombustor (24) having a cross-sectional shape complementary to that of flame end of the burner (10) can be disposed on the flame end (22) of the burner housing (18) to further enhance combustion and protect the burner (10) from the furnace atmosphere.
