Abstract

A comprehensive three-dimensional model is developed to simulate forestry residues gasification in a fluidized bed gasifier using Eulerian-Lagrangian method. Both complex gas-solid flow and chemical reactions are considered. The model is based on the multiphase particle-in-cell (MP-PIC) method, which uses an Eulerian method for fluid phase and a discrete particle method for particle phase. Homogenous and heterogeneous chemistry are described by reduced-chemistry and the reaction rates are solved on the Eulerian grid. Simulations were carried out in a laboratory scale pine gasifier at different operating conditions. The predicted product gas contents and carbon conversion efficiency compare well with the experimental data. The formation of flow patterns, profiles of temperature and distributions of gas compositions were also obtained.
