Computational fluid dynamics (CFD) is a branch of fluid mechanics that analyzes and solves problems involving fluid flows using numerical analysis and data structures. CFD is a simulation technique used to predict what will occur, quantitatively when fluids flow, often with simultaneous heat flow complication, mass transfer, phase change, chemical reaction, mechanical movement of (pistons, fans, etc.), stress and displacement of immersed or surrounding solids. It helps to simulate vast area of fluid flow problems ranging from simple flow through pipe to multidisciplinary problems involving complex chemical processes. In the existing work by Computational Fluid Dynamics analysis combustion of natural gas is carried out by integrating manual chemical reactions. Given the significance of NOx emissions in boilers, NOx predictions may be the most significant improvement in industrial system using CFD analysis. Conditions of combustion within the boiler furnace were simulated by Fluent CFD software at a 300, 400, 450 and 600 swirl angles. CFD Fluent software is used as a tool to generate the fired gas burner's three-dimensional model. The CFD simulations provide contours of temperature distribution, contours of CO2 mass fraction, contours of H2O mass fraction, contours of NOx and heat flux profiles to the furnace walls. As the different vane angle geometries are studied, it is found that as swirl vane angle and swirl number increases, NOx formation decreases.
