1. the method by oxy-fuel burners melting furnace charge in stove, described stove comprises a charge melting zone and at least one upstream flue gas outlet, this charge melting zone is restricted to the district being positioned at the line upstream distinguishing solid material and melting material, this upstream flue gas outlet is arranged on one or more cross side of described stove, it is characterized in that, in charge melting zone:

  • The oxy-fuel burners combustion of liquid fuel that-contiguous described upstream flue gas outlet is arranged;

    -at least one oxy-fuel burners burn gas fuel arranged away from described upstream flue gas outlet;

    Wherein, described stove also comprises a heating zone and a fining cell, this heating zone is restricted to the district covered by the flame of oxy-fuel burners, and this heating zone comprises a part for charge melting zone and is adjacent to the district in downstream, charge melting zone, this fining cell is restricted to the district being positioned at downstream, heating zone, and this fining cell is not heated;

    In heating zone, closest to the oxy-fuel burners combustion of liquid fuel of fining cell.
