%X The investigation on the horizontal plug flow of polypropylene granules was conducted in a dense-phase pneumatic conveying system with pipeline of 50 mm in diameter, 11 m of vertical section and 19 m of horizontal section. The mini-pressure drop sensor and solid pipeline section concentration detector were used. It is found that the length of plug moving in the pipeline changes with time. The profiles of cross-sectional solid average concentration and pressure gradient along plugs vary with the gas velocity. The pressure drop across the plug is proportional to the square of plug length and independent of the gas velocity.
