Valorization of Moroccan Olive Cake in Small Scale Bumer Through Stirling Engine: Case Study

Abstract

The purpose of the current study is to valorize Moroccan olive waste in a small-scale burner in order to produce electricity through Stirling engine. To fulfill this purpose, a comprehensive computational fluid dynamics (CFD) modeling of the combustion of the olive cake was presented, in which the pulverized olive particles are injected into the burner through two concentric injection tubes. The numerical method is based on Reynolds averaged Navier-Stokes (RANS) approach opting the realizable $\mathrm{k}-\varepsilon$ turbulence model for turbulence, the non-premixed combustion model for gas combustion, the Lagrangian method (DPM) for the discrete second and the PI for radiation. The contours of velocity, turbulence kinetic energy, DPM burnout and mass of NO was presented and discussed.
