Comparison of moroccan argain nut shell and olive cake combustion to determine the best combustible for CHP system and for the thermodynamic cycle

Abstract

The current research aims to valorize Moroccan agricultural waste by using it as a combustible fuel. The physicochemical properties of argan cake were determined and the results were compared with other studies of argain nut shell and olive cake. A comparison of argain nuts shell, argain cake, and olive cake was carried out in order to determine the best combustible in terms of energy, emissions and thermal efficiency cycle. The CFD modeling of their combustion was presented using Ansys fluent software, The Reynolds averaged Navier-Stokes (RANS) method is the foundation of the numerical approach, which models the turbulent flow using realizable.k-ε, A non-premixed combustion model is used for the gas phase, and a Lagrangian approach is chosen for the discrete second phase, there was a good agreement between the numerical and experimental data, as well as Wolfram Mathematica 13.1 is used to predict the mechanical work generated by the Stirling engine, and the result encourages the use of studied biomasses as combustible in order to generate heat and power.
