Question 1

What is the main objective of the study?

Accepted Answer

To determine the proper aeration proportion fed to the supply and recycle chambers that affects the optimal operating point and the maximum solid circulation rate in a CFB reactor with a U-type loop seal.

Question 2

Why does aeration influence the solid circulation rate in CFB reactors?

Accepted Answer

Loop seal aerations drive solid particles from the return leg toward the riser, increasing solid circulation rate with higher air velocity and flow rate, while decreasing it with increasing particle density and size due to inertia.

Question 3

What gap in knowledge does the paper address?

Accepted Answer

The exact aeration ratio supplied for optimum operation of loop seals is not known, especially regarding different proportions at the supply and recycle chambers.
