ANALISIS PENGARUH PRESSURE INLET, TEMPERATURE INLET, DAN HEATING VALUE TERHADAP PEMBENTUKAN NOX PADA PEMBAKARAN LNG DENGAN NON-PREMIXED FLAME MENGGUNAKAN METODE COMPUTATIONAL FLUID DYNAMICS

Abstract

This research is a study on the formation of NOx emissions with 3 predetermined variables, namely inlet pressure, inlet temperature, and heating value where these three variables are variables that have a major role in a non-premixed flame combustion reaction. This research uses a 2D computational simulation method. Fluid Dynamics. The simulation was carried out 12 times with different values of pressure, temperature and fuel composition. The results of the study show that the inlet pressure and inlet temperature variables respectively have a significant effect on the formation of NOx emissions, while the heating value variable does not show a contrasting effect on the formation of NOx emissions. As for suggestions from the authors where CFD simulations are carried out on devices with better specifications with the aim of speeding up the iterations carried out in the simulation and producing a better number of meshes. In addition, CFD simulation can be carried out in 3D method so that it can simulate the flows in the combustion reaction from various axes.
