Determination of the Bed Hydrodynamics by MFIX-PIC in the Biomass Gasification Process of Circulating Fluidized Bed

Abstract

In this study, it was aimed to control the formation of flow regimes planned to be in the gasification process on the model, and the hydrodynamic structure of the circulating fluidized bed gasifier was obtained using the MFIX program. For this purpose, a model was established before pilot scale systems and hydrodynamic modeling was performed by entering the system dimensions that were calculated analytically. Because it is a necessary condition from the point of view of the chemical reaction to ensure the fluid bed regime of the gasifier, which is designated as a solid model, is a necessary condition. For this reason, the system whose geometry was determined and semi-empirical modeling was performed was modeled under previously determined operating conditions using the PIC (Eulerian-Lagrangian) model in the MFIX package program.
