Oxyfuel flames are known for their bright colour and hot combustion temperatures. The combustion
process without nitrogen has an intense and sharp flame. When burning fuel with air the nitrogen content
of air (ca. 78 vol.-%) cools and dilutes the flame and combustion reactions. Nitrogen does not
take part in the combustion reactions, but enters the combustion as a cold gas and leaves it at higher
temperatures. Oxyfuel flames can be above 2300 °C and air fuel flames are typically in the range of
1700 °C (non-adiabatic). The heating and melting of nonferrous metals must be energy efficient and
low in emissions. This paper will describe the features of flameless oxyfuel combustion and how they
impact the production of non-ferrous metals.
