CFD Simulation of the CO Emissions of Pollutants Contained in Flames H2-C3H8/Air

Abstract

Abstract A mathematical simulation was developed using CFD in this study for the nonpremixed combustion of two co-axial jets of a mixture consisted of propane, hydrogen, and air. The combustion chamber is represented in a three-dimensional cylindrical shape. The study aimed to evaluate the chemical and thermal properties of the mixture in the burner by adopting the following variables: temperature, axial velocity, and emitted CO. The study aims to identify and reduce carbon monoxide emissions to the environment as it is toxic pollutant. The addition of hydrogen to propane because it is a clean fuel that does not emit carbon monoxide as is the case with propane. In this study, the flame propagation velocity of hydrogen gas was compared to that of propane fuel.
