Abstract

Método para reducir las emisiones de oxido de nitrogeno en una combustion. Se quema combustible en una primera zona, generándose así oxidos de nitrogeno. Se alimenta combustible suplementario en otra zona en condiciones reductoras. Al mismo tiempo, se ajusta la temperatura de tal manera que los oxidos de nitrogeno se convierten esencialmente en cianuro de hidrogeno. Por ultimo, se alimenta aire para finalizar la combustion y convertir el cianuro de hidrogeno en nitrogeno.
