In the present work, a computational fluid dynamics (CFD) model is used to assess devolatilization of biomass under high-temperature condition. The CFD code is based on a multiscale Eulerian–Lagrangian solver previously developed in the framework of OpenFOAM. A particle shrinkage model proposed by Colomba Di Blasi is implemented in this study to better calculate size evaluation of biomass particle...
In this study, gasification behavior of high heating-rate chars were investigated using an entrained flow reactor with an optical particle-sizing pyrometer. Two biomass chars produced from forest residue and torrefied forest residue as well as one coal char produced from low sulfur Black Thunder subbituminous coal have been gasified at temperature over 1700K. Both the char surface temperatures and...
