Kurzfassung
The present dataset is composed of the experimental results presented in the journal publication "Pulverized coal swirl flames in oxy-fuel conditions : Effects of oxidizer $\mathrm{O_2}$ concentration on flow field and local gas composition". Experiments were conducted on a series of 40kWth aerodynamically stabilized pulverized lignite coal flames, all of them under oxy-fuel conditions. The three studied test flames are named: Oxy23, Oxy27, Oxy33, based on the $\mathrm{O_2}$ enrichment levels in the oxy-fuel mixtures. Data from three different types of measurements are presented: 2D velocity profiles from laser Doppler anemometry (LDA); Gas composition profiles by employing a sampling probe and Fourier-transform infrared absorption spectrometry (FTIR); Solid-particle temperatures at different locations in the flame, estimated from radiation measurements using an intrusive optical probe.
