Abstract: This paper evaluates the impact of alternative fuels utilised in a cement facility in Central Anatolia, Turkey, on CO₂, SO₂, H₂O, and NO_x emissions. We implemented Chemkin-Pro and NASA CEA to investigate 16 fuel scenarios at temperatures between 973.15 K and 1,473.15 K. The modelling results demonstrate that high volatility and oxygen content in refuse-derived fuel contributed to an increase in NO_x formation. Conversely, the low volatility and high carbon content of petcoke led to a decrease in NO_x emissions. In scenario 13, the tyre and refuse-derived fuel combination yielded the lowest NO_x emissions.

Keywords: alternative fuel; cement production; CO₂ reduction; combustion gas emission; global warming; RDF; TDF.
