✦ Synopsis

Mean and fluctuating velocity components and turbulence characteristics of the flow in the outlet of a cavity bluff-body burner were measured using three-dimensional laser particle dynamics anemometry (3D PDA). Results are also given on the choice of model particles, particle diameter distribution in and out of the recirculation zone, particle number density and volume flux distribution, and the combustion process for low-volatile coals. The experimental results not only provide an explanation of the mechanism of flame stabilization of the cavity bluff-body burner, but also demonstrate the potential of this kind of flame stabilization in industrial use.

On the basis of analysing the lean flammability limits of pulverized coal combustion and the mechanism of flame stabilization of low-volatile pulverized coal by the bluff-body burner, a new principle is presented that improves ignition and flame stability of low-volatile pulverized coal. For example
