Oxyfuel combustion of lignite in a non-stoichiometric operating two burner arrangement

► Investigations on oxycoal combustion in a non-stoichiometric two burner arrangement. ► Significant reduction of recirculation while fulfilling all requirements on temperature limitation. ► Comparable NO and CO emissions to the stoichiometric air-like oxyfuel process. ► Negligible differences in combustion characteristics when changing between wet or dry recirculation.
