Abstract

Un método para optimizar condiciones de combustión en una caldera de lecho fluidizado en la que se alimenta gas de combustión oxigenado a dos o más niveles de altura, el primero de los cuales es un nivel primario (P), que está ubicado a la altura de la parte inferior de un horno, y el segundo es un nivel secundario (S), que está ubicado cerca de una altura de alimentación de combustible (F), nivel secundario (S) por encima del cual puede haber aún otros niveles de alimentación de gas de combustión (T, ...), caracterizado por la producción de unos gases de combustión (15a, 15b; 16a, 16b; 28a, 28b) que tienen diferentes contenidos de oxígeno mediante la mezcla entre sí de aire y/u oxígeno puro y gas de escape circulado en una relación tal que cada gas de combustión se dota de un contenido de oxígeno deseado, y por la alimentación de al menos uno de dichos niveles de alimentación de gas de combustión (P, S, T, ...) en diferentes puntos en la dirección horizontal del horno (11) con gases de combustión (15a, 15b; 16a, 16b; 28a, 28b) que tienen diferentes contenidos de oxígeno de modo que se forman zonas de diferente contenido de oxígeno en la dirección horizontal del horno (11).
