Numerical Investigation of a Burner Configuration to Minimize Pollutant Emissions

Combustion process in furnaces is affected by various factors, so that the aim of present research is investigation on one of the aforementioned factors on the combustion process of burners which are uses in refineries and petrochemical industries. This paper presents Computational Fluid Dynamics (CFD) model of a non-premixed burner and emphasis is placed on the study of the angle of gas which is injected of burner tip to combustion zone. In the present work aim is finding the best geometry of burner tip by testing the different angles of gas injection to optimize the burner performance and decrease the pollutant emission. The best geometry can bring significant benefits, including lower NOx and CO emission, and overall high combustion efficiency.
