The flow behavior of a gas-solid highly concentrated mixture in a spiral tube is discussed in terms of the pressure loss for a horizontal pipe and 90°bend flows using about 33 m of pipeline. It has been clarified that the blockage of potassium alum pellets through the spiral tube pipeline occurs in a lower mean gas velocity range than that of a circular pipe pipeline, and a drag reduction is obtained in the case of the transportation of a solid particle in the spiral tube. Howevers, the pressure loss of an ultrafine solid particle mixture flow in the spiral tube pipeline, increases compared to that of a circular pipeline. Fluctuation of measured wall pressure data of the spiral tube decreases compared to that of a circular pipe.
