Abstract:
A CFD case study was done to learn the impact of Flue Gas Recirculation in a horizontal axis small scale furnace. Flue Gas Recirculation was performed to seehow the emissions are affected with a change in recirculation ratio. The aim was to find out the optimum Recirculation Ratio at which the emission is minimum but the efficiency of combustion is not compromised. A comparative analysis was presented in order to determine the various factors affecting NOx and SOx emission.Ansys FLUENT 2020 R2 was used to simulate the combustion environment. It was found out that by using flue gas recirculation, NOx and CO2 emissions can be reduced significantly, and SOx emission can be reduced only slightly. The temperature contour for the recirculation scenarios were comparable to that of the air fired case. Increasing temperature also resulted in an increase in NOx emission.
