001010879 520__ $$aThis data publication contains the quantitative values of the narrow-band imaging and laser Doppler velocimetry measurements published in the conference article, named 'Experimental Study on the Influence of Methane-Cofiring on Pulverized Coal Flames under Air and Oxy-Fuel Conditions'. 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.
