Abstract
A burner assembly for enabling a staged combustion has a high-impulse burner having a central fuel feed line and an oxygen feed line arranged coaxially therewith, and has at least one high-impulse oxygen lance which is arranged vertically above the high-impulse burner. A controller allows for switching between a stoichiometric operation of the high-impulse burner and a staged operation, in which at least a portion of the oxygen required for the stoichiometric combustion of the fuel is supplied via the at least one oxygen lance.
