The task of the research work is to conduct experimenal investigation on the hydrodynamic behaviours of air-pulverized coal two phase flow and also on the exploration of the way to enhance concentrating process of coal particle in exit zone of burners.
Two burners have velocity injection difference, one have the mixture flow of pulverized coal and air, the other have only air. Mean velocity, density and turbulent properties of pulverized coal were measured by PDA.
The research results that similarity for mean velocity, density and turbulant properties were revealed X/D=6 from exit of burner. Density profiles of pulverized coal show maximum values near Y/D=7 and also have effect on air jet.
