A CPFD analysis of flow pattern under air and O2/CO2 mixture as a fluidizing gas in a Circulating Fluidized Bed Reactor |
| 초록 |
In this study, cold mode experiment have been performed in a Circulating Fluidized Bed (CFB) reactor with air and O2/CO2 mixture were used as fluidizing gas. Firstly, the CPFD simulations result were compared with experimental measurements of air and O2/CO2 mixture cases. The main objective of work is to evaluate pressure fluctuations along the height of the riser and their power spectral densities (PSD) using Fast Fourier Transform (FFT) analysis. Spectral analysis shows different patterns along the height of riser depending on flow structure. The results also show unique characteristics under difference air and O2/CO2 mixed cases in the bottom and the upper section of the riser. This work present CPFD as a useful tool to study hydrodynamic behavior in O2/CO2 condition. |
