Reduction Of Co Emissions In The Environment By Preheating The Air In A Combustion Chamber

Résumé: In this paper, we studied numerically the effect of the preheating temperature of air in a non-premixed cylindrical (3D) combustion chamber. Using the commercial CFD code FLUENT, the characteristic parameters of the reactive flow, namely the axial velocity, the temperature and the mass fraction of carbon monoxide CO, was calculated. The study of this phenomenon consists in using a special treatment of mathematical models. The considered approaches were used to overcome the closure of the equations of the aero-thermo-chemical balance. The main objective of this work is to study the behavior of these parameters following the variation of the air inlet temperature. The utility of this method is to facilitate combustion chamber operation and a significant reduction in carbon monoxide emission.The obtained results show that the variation of the air temperature presents a great effect on the studied parameters. We have found that the air inlet temperature T=750 K is the best solution for CO carbon monoxide emission.
