Effect of fluidizing velocity on gas bypass and solid fraction in a dual fluidized bed gasifier and a cold model

- N2 bypass through the chute between FFB and BFB in a dual fluidized bed gasifier was studied.
- The effect of fluidizing velocity on the hydrodynamics of the DFBG and DFCM was investigated.
- Correlations for height-averaged solid fraction in the bottom of FFB and BFB were developed.
- The correlations are useful for potential industry applications.
