OXY-BURNER WITH STAGED COMBUSTION

摘要

The invention relates to a staged-combustion oxy-burner in which a primary oxidiser is injected together with the fuel while the injection of a secondary oxidiser is spaced from the fuel injection, wherein the primary oxidiser has a temperature at the fuel passage inlet lower than 100°C and the secondary oxidiser has an oxygen content of at least 80 vol. % and a temperature at the inlet of the upper injection passage thereof higher than 100°C.
