Abstract

Método para la optimización de la combustión de combustible en una cámara de combustión de una central eléctrica, con las siguientes etapas: - medición (28) de una distribución real de la concentración de una sustancia en la cámara de combustión en, al menos, una dimensión, - evaluación (32) de la distribución real de la concentración, - control (34) de la combustión del combustible de manera que se genere una distribución simétrica de la concentración de la sustancia en la, al menos una, dimensión, y - durante la evaluación (32) se determina, al menos, un número característico para la simetría de la distribución real de la concentración, y durante el control (34) se modifica, al menos, un parámetro de control en relación con el, al menos un, número característico.Method for the optimization of the combustion of fuel in a combustion chamber of a power plant, with the following stages: - measurement (28) of a real distribution of the concentration of a substance in the combustion chamber in at least one dimension, - evaluation (32) of the actual distribution of the concentration, - control (34) of the combustion of the fuel so as to generate a symmetrical distribution of the concentration of the substance in the at least one dimension, and - during the evaluation (32) at least one characteristic number is determined for the symmetry of the real distribution of the concentration, and during the control (34) at least one control parameter is modified in relation to the at least A characteristic number.
