Pulverized coal torch combustion in a furnace

Aerodynamics of flame combustion of a pulverized coal was studied experimentally using a laboratory setup with a thermal power of 25 kW. The axial and tangential velocity profiles were measured with the co-and counter-swirl of the first and second degrees of the burner. Averaged velocity profiles were measured by a two-component LDA system. The temperature was also measured on the walls and axis of sections of the pulverized coal burner. The temperature distributions were obtained at different coal dust flow rates as well as at co-and counter-swirl. The results obtained allow us to conclude about the efficiency of flow mixing at pulverized coal combustion.
