Definitions

  • the third step c) is the phase of superheating the liquid aluminium.
  • the output power of the burner is preferably controlled depending on the temperature of the liquid metal as already known from the prior art.
  • oxyfuel burner shall mean a burner which is operated with a fossil fuel, in particular a liquid or gaseous fuel, and a gas containing more than 21 % oxygen.
  • the gas contains at least 80% oxygen.
  • the oxyfuel burner can also be operated in the all oxyfuel mode meaning that the oxygen containing gas is technical pure oxygen.
