Because of high environmental impact and energy costs, many cement plants tend to substitute waste-derived fuel for fossil fuels. The combustion of waste-derived fuels in the rotary kiln burner is more challenging than in the precalciner where there is a less strict temperature requirement and where gravity facilitated feeding is possible. This paper present a 2D computational fluid dynamic conducted for a cement rotary kiln burner. Simulations are performed using commercial COMSOL multiphysics and are conducted for coal and olive pomace using Euler-Euler model and the k-ᵋ model for swirl and jet air transport in the burner inlet. The predict result will after that using in the combustion model.
