Experiments are carried out using a pilot-scale down-fired cylindrical combustion chamber equipped with a swirl burner. Studied operating conditions of flames of lignite/methane fuel mixtures have an identical thermal output of 40 kWth, with the thermal output share of methane gradually decreasing from 50 $vol.\%$ to 0 $vol.\%$ while the lignite share (Rhenish lignite) increased from 50 $vol.\%$ to 100 $vol.\%$ (self-sustained condition). To visualize flame structure and to identify reaction zones, narrow-band imaging is employed. Narrow-band flame imaging is conducted at two different wavelengths (OH* and CH* radical band heads). A detailed flow field characterization of the respective flames is conducted by two-dimensional laser Doppler velocimetry measurements. Radial profiles of axial and tangential velocities have been determined using an optical long-range laser Doppler velocimetry (LDV) system operated in backscatter mode and mounted to a traverse. Solid fuel particles are used as flow tracers. Results and the experimental conditions from the present dataset are in depth described in the conference article.}, cin = {412610}, cid = {$I:(DE-82)412610_20140620$}, pnm = {DFG project G:(GEPRIS)240966705 - Experimentelle Untersuchung der Biomasseverbrennung zur Validierung numerischer Simulationen (C01) (240966705) / DFG project G:(GEPRIS)215035359 - TRR 129: Oxyflame - Entwicklung von Methoden und Modellen zur Beschreibung der Reaktion fester Brennstoffe in einer Oxyfuel-Atmosphäre (215035359)}, pid = {G:(GEPRIS)240966705 / G:(GEPRIS)215035359}, typ = {PUB:(DE-HGF)32}, doi = {10.18154/RWTH-2025-04398}, url = {https://publications.rwth-aachen.de/record/1010879}, }
