Design and analysis of moderate or intense low-oxygen dilute combustion burner

Abstract

Analysis of the Moderate and Intense Low-Oxygen Dilution (MILD) combustion burner is performed using commercial CFD code ANSYS. The burner is designed in such a way to be a non-premixed and open burner. Four exhaust gas recirculation (EGR) pipes are used to transport part of the exhaust gas from exhaust to the inlet where it is mixed with the fresh oxidant. The chamber temperature distribution of MILD combustion chamber is found to be reduced in comparison with normal burner with conventional combustion. This leads to reduction in the exhaust gas temperature at the MILD combustion burner outlet and reduces the NOx emissions.
