Method and Device for Optimizing Combustion in a Power Plant

摘要

Methods and devices for optimizing combustion of fuel in a combustion chamber of a power plant are provided. A real concentration distribution of a material and/or a real temperature distribution in the combustion chamber is measured in at least one dimension. The real concentration distribution and/or temperature distribution is evaluated and a combustion of fuel is controlled such that a symmetric concentration distribution and/or temperature distribution in the at least one dimension arises. During the evaluation at least one characteristic of the symmetry of the real concentration distribution and/or temperature distribution is determined, and during the controlling at least one control parameter is changed depending on the at least one characteristic.
