Abstract Scope Flue gas recirculation (FGR) has been tested in a pilot scale silicon production process. FGR for the silicon process has a potential of increasing CO<sub>2</sub> concentration in the off gas, which will be beneficial for future carbon capture, and reducing NOx emissions. An existing 400 kVA pilot furnace setup was modified to be able to recirculate flue gas and equipped with gas analysis equipment to analyze both the flue gas and the mixed combustion gas entering the furnace. Over a running period of 80 hours, including 32 hours of startup, twelve different combinations of FGR ratios and flow rates was tested using typical industrial raw materials. Increased CO<sub>2</sub> flue gas concentrations was successfully demonstrated with concentrations over 20 vol % CO<sub>2</sub> in the flue gas. Emissions of NOx was shown to be reduced when isolating stable comparable periods within each tapping cycle.
