Biomass combustion simulation by using the eddy dissipation concept model

Abstract

At the present, the numerical techniques, such as computational fluid dynamic (CFD) is useful engineering tool for design and optimization process. The CFD gives a possibility to predict the combustion phenomena. This article deals with biomass combustion simulation by using the Eddy Dissipation Concept (EDC) model. The Eddy Dissipation Concept (EDC) model is an extension of the Eddy Dissipation model to include detailed chemical mechanisms in turbulent flows. It assumes that reaction occurs in small turbulent structures. For mathematical simulation was used 3D model, which consist of combustion chamber with retort burner and flue gas tract with baffles used for capturing of particulate matter. The model has three types of air inlet and one outlet on the end of the chimney. In the results, you can see temperature, velocity and particle profiles of this model. Based on the results can be concluded that the baffles placed in the flue gas tract can be useful for separation of particulate matter in the small heat source, such as a stove.
