A phase Doppler anemometer system was used to study gas-particle flow characteristics of a conical rings concentrator for a centrally fuel-rich burner. The influences of distance between adjacent rings on the distribution of mean axial velocity, particle volume flux, particle number...

Within a gas/particle two-phase testing facility, multi-level concentrators were investigated by obtaining gas/particle two-phase characteristics of each concentrator within a centrally fuel-rich swirl burner. Measurements of velocities, particle volume flux profiles and relative particle number...
