CFD modelling of biomass boilers - a review of the state of the art

Abstract: Combustion is the main method of converting biomass to energy, either by direct heating systems or by boilers. By means of CFD models, it is possible to optimize the behavior of those systems and improve significantly its performance, without incurring the economic and environmental cost of experimental studies. However, modelling of biomass combustion is a complex process that requires a large number of sub-models and computational resources for a detailed description, therefore, different approaches have bee… Show more

“…Computational Fluid Dynamics (CFD) modeling is a cost-effective tool to study and optimize the process; which is not a trivial task since successful modeling of solid combustion furnaces requires appropriate sub-models to simulate the relevant combustion, flow and transfer processes, and their interactions, whose complexity affects the accuracy of the results and computational time (3). Due to that, it is a topic that is still under investigation; a full review is given in the papers of Karim and Naser (4), Dernbecher et al ( 5), Bhuiyan et al ( 6), Khodaei et al (7) and García et al (8,9). Moving grate furnaces have been the most studied systems because they are widely used in industry (8); however, fixed bed systems of low power have gained popularity in recent years due to their low operating cost, simplicity and low requirements in terms of fuel preparation and transportation (7,10,11).…”

“…However, there are relatively few OpenFOAM-based models reported in the literature to study the combustion of solid biomass. Most of the studies of this subject are performed using the software ANSYS® (8,9). In order to contribute to the study of the combustion in panela furnaces, in the current work, a comprehensive two-dimensional numerical model was developed in OpenFOAM.…”
