FLAME PROPAGATION IN HYBRID “COAL-METHANE-AIR” AEROSUSPENSIONS
Journal Title: Физика аэродисперсных систем - Year 2015, Vol 0, Issue 52
Abstract
Results of laminar flame propagation experimental studies on hybrid aerosuspensions ≪methane-coal-air≫ are presented. Combustion of fine coal dust clouds (r0 = 8 microns, volume 4 ・ 10-3m3) and iron oxide clouds (r0 = 5 microns, volume 4 ・ 10-3m3) is investigated in isobaric conditions. Volumetric methane concentration was 6%. Comparison of visible and normal flame propagation velocities of mixtures "methane - air", "methane - coal - air" and "methane - inert component - air" testifies that fine coal particles increase flame propagation rate.
