Experimental investigation on the interaction of flame stability, radiation, burnout, and emissions in a semi-industrial-scale swirl-stabilised oxy-fuel furnace (C07*)

• Subject Area: Energy Process Engineering
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 215035359

The aim is to improve the understanding of the interaction of hydrodynamics, chemical reactions, heat transfer, and pollutant formation in oxy-fuel combustion of solid fuels under conditions similar to those prevailing in industrial applications. Experiments are conducted in a water-cooled pulver-ized fuel fired 1 MWth furnace using a variety of complementary measurement technologies at var-ious measurement ports along the furnace axis. Additional experiments are performed by TGA and an entrained flow reactor to determine the formation of nitrogen and chlorine species during bio-mass pyrolysis and char oxidation.
