Oxygen-fired low-NOx gas burner and combustion method

摘要

Reduced NOx staged combustion method and corresponding burner assembly, whereby an eductor-jet pump (30) is used for generating a mixed jet of primary fuel and primary ballast gas which is injected into the combustion zone in contact with a jet or primary oxidizer so as to generate a primary flame (110) and whereby secondary oxidizer and/or secondary fuel is injected at a distance (l os /l fs ) from the mixed jet.
