Numerical Simulation of Methane-Air Nozzle Burners for Aluminum Remelt Furnaces

Abstract A turbulent nozzle-mix burner, suitable for industrial use in aluminum remelt furnaces has been numerically simulated using FLUENT software. The burner has been modeled as a vertical axisymmetric arrangement of fuel duct at the center, surrounded by a coaxial annular duct of air. The ducts discharge into a confined environment, formed by a chimney, placed coaxially with the ducts. The effects of fuel velocity and air …
