- •
High solid flux and solid holdup were achieved simultaneously in CFB riser with group B particles.
- •
Transition point from fast fluidization to dense suspension upflow was determined.
- •
Solid holdup exhibited a steep parabolic profile in the radial direction of the riser.
- •
Geldart group B and A particles showed similar slip characteristics in high-density CFB risers.
