Abstract
Procedimiento para la reducción catalítica de óxidos de nitrógeno en el gas de escape (A) de una instalación de combustión (1), especialmente de un motor Diesel, donde en función de parámetros que caracterizan el estado de funcionamiento de la instalación de combustión (1), el gas de escape (A) y/o un catalizador (5), se determina una cantidad a dosicar de una solución de agente reductor y se introduce en la dirección de la circulación del gas de escape (A) delante del catalizador (5) en el gas de escape (A), siendo liberado un agente reductor a partir de la solución de agente reductor (R) y siendo convertido con los óxidos de nitrógeno en el catalizador (5), caracterizado porque se determina la concentración de la solución de agente reductor (R) de una manera discontinua durante y/o antes de la introducción de la solución de agente reductor en el gas de escape y se adapta la cantidad a dosificar a la concentración determinada.
