Abstract
The invention relates to a method for controlling a combustion in a furnace (100) which is heated by a burner (160) with at least one oxygen lance (120), wherein a fuel is supplied via a fuel supply (110) of the burner (110) and oxygen is supplied at least in part with a high speed of 100 m/s or more by the at least one oxygen lance (120), and wherein oxygen in an overstoichiometric range is supplied. The invention further relates to a furnace (100) for carrying out said method.

1-12. (canceled)
A method of closed-loop control of combustion in a furnace (100) heated by a burner (160) having at least one oxygen lance (120), compromising:
- supplying fuel by a fuel feed (110) of the burner (160);
- and supplying oxygen at least partly at a speed of at least 100 ms through the at least one oxygen lance (120), wherein the supplying the oxygen is in a superstoichiometric range.
A furnace (100) having closed-loop control of combustion in the furnace, comprising:
- a burner (160) having at least one oxygen lance (120), the burner (160) configured to supply fuel via a fuel supply (110), and the at least one oxygen lance (120) configured to supply oxygen at a speed of at least 100 m/s through the at least one oxygen lance (120);
- a sensor unit (140) for detection of a stoichiometry;
- and
- a control unit (150) to adjust the oxygen supply responsive to a signal from the sensor unit (140) such that an oxygen concentration supplied is within a superstoichiometric range.
