| Abstract: | In this paper,by means of 3D Particle Dynamic Analyzer(3D-PDA),the gas-particle two-phase flow in the primary air channel of some new-type direct-flow pulverized coal burner of a utility boiler was experimentally measured.The distributions of velocity and turbulent kinetic energy of gas-particle two phases,as well as the particle diameters and concentrations were obtained.Through the analysis and discussion of the experimental results,the mechanism of the gas-solid two-phase flow in the burner and the influ... |
