Paper Abstract

Gas-solid two-phase flow experiments of fly ash were carried out with compressed air being adopted as dynamic force in the long-distance pipeline. Groups of GP/DP transmitters were installed along the pipeline. The solids velocity was expressed by the distance versus time interval of pressure signal of the two transmitters. Thus the trends of particle velocity and pressure drop along the pipe were given experimentally and theoretically. Meanwhile, according to experimental data, resistance properties along the pipeline were performed experimentally and transport mechanism in dense-phase pneumatic conveying was analyzed. Based on dynamic balance of gas-solid two-phase flow, associated with experimental data, pressure drop calculation equation of horizontal pipe in dense-phase pneumatic conveying was established.
