  • Method and apparatus for continuously ensuring sufficient quality of green pellets
    Patent number: 11549160
    Abstract: A method for controlling pellet quality in iron ore production includes the steps of mixing water, binder and iron ore particles in at least one mixer to form a mixture (step (i)) and pelletizing the mixture into green pellets (step (ii)). Between step (i) and step (ii), a part of the mixture is taken in a sampling operation, formed into a test specimen and subjected to a test.
    Type: Grant

  • Method for controlling the fuel supply to burners of a burner group and burner controller
    Patent number: 9228783
    Abstract: A method for controlling a fuel supply to a plurality of burners of a burner group includes determining a temperature in the burner group as a control variable. The fuel supply to the burners of the burner group is specified in dependence on a control deviation of the temperature determined in the burner group to a specified setpoint temperature. The fuel supply is a common mean fuel supply that is specified for all of the burners of the burner group by a temperature master controller. The fuel supply is corrected for each of the burners or burner subgroups of the burner group. Each of the burners or the burner subgroups have a fuel supply slave controller. The fuel supply slave controllers use at least, one disturbance variable associated to the respective burner or the respective burner subgroup so as to perform the correcting.
