A threecomponent particledynamics anemometer is used to measure, in the nearburner region, the influence of the primary air ratio on the gas/particle twophase characteristics for a centrally fuel rich swirl coal combustion burner, on a gas/particle two phase test facility. Velocities, particle volume flux profiles and particle relative number concentrations were obtained. With a low primary air ratio, the axial velocities for gas and particles on the chamber axis are always small and easily reach the negative, and the central recirculation zone is easily formed and much closer to the outlet of the burner. In each crosssection, in the radius range from R&lt;d=0 to 0.11, the particle volume flux with r1=23.85% is always larger than that with r1=16.56%, which means the degree penetration with a high primary air ratio is higher than that with a low primary air ratio. The influence of gas/particle flow characteristics with a different primary air ratio on combustion has been analyzed.
