Abstract：This paper is focused on the application of the portable X-ray photography technique to measurement of the radial and axial profiles of solid concentration in a gas–solids riser, a pilot-plant-scale downer, and a nano- agglomerate fluidized bed of carbon nanotubes. Twenty to thirty images with 100~200 ns X-ray pulses were processed to get a time-averaged concentration profile. Results show that this technique is a promising non-intrusive method to get time-averaged solid concentration profiles in gas–solids two phase flow systems.
