Method and Device for Optimizing Combustion in a Power Plant

A method of optimizing combustion of fuel in a combustion chamber of a power plant, comprising:

• measuring a real concentration distribution of a substance in the combustion chamber in at least one dimension;
• evaluating the real concentration distribution;
• controlling a combustion of fuel such that a symmetric concentration distribution of the substance is created in the at least one dimension;
• determining at least one characteristic for a symmetry of the real concentration distribution during the evaluating;
• and
• modifying at least one control parameter depending on the at least one characteristic during the controlling.
