Description

The reactor’s conical shape promotes efficient heat transfer and mixing, resulting in homogeneous temperature distribution throughout the biomass feedstock. The spouted bed configuration improves particle circulation, resulting in faster pyrolysis processes and shorter biomass residence time within the reactor. This produces higher product yields and quality than typical pyrolysis processes.

This project has tried to simulate biomass pyrolysis in a conical spouted bed reaction using ANSYS Fluent software. Regarding the difficulties through the project, a valuable reference paper entitled “CFD modeling and experimental validation of biomass fast pyrolysis in a conical spouted bed reactor” was chosen to take some information.

Biomass Pyrolysis in Conical Spouted Bed Reactor CFD Simulation

Simulation Process

In the primary phase of the project, 2D geometry is designed with blocking for later steps in mind. The blockings allow us to perform a high-quality structured grid in ANSYS Meshing.

The most challenging part of the project is dedicated to solver settings. The biomass pyrolysis is happening over time, so it is a Transient (Unsteady) study. The Eulerian multiphase model is employed to model both phases. One is gas phase and the other one is the biomass bed that is modeled considering granular. There are several key factors related to granular properties that affects the simulation. It is already mentioned that these parameters are taken from reference paper. Further, Species Transport module models volumetric reactions.

 

Post-processing

Animation revealed process dynamics in simulated biomass pyrolysis in a conical spouted bed reactor. Heat transfer and biomass conversion were efficient, with the reactor mixing and interacting biomass particles and inert bed material well. A uniform reactor temperature enabled excellent pyrolysis conditions throughout the biomass bed. The spouted bed arrangement also generated a strong spout, improving gas-solid interactions and biomass devolatilization. Results show that the conical spouted bed reactor is successful for biomass pyrolysis, providing insights for optimizing process parameters and reactor performance in bioenergy production.
