Abstract

Esta invención se refiere a un método para evaporar un agente reductor acuoso, para reducir el NOx en los gases de la cobustión, en un sistema de combustión. Se colocan intercambiadores de calor en la trayectoria de los gases de la combustión, de modo que el calor de los gases de la combustión caliente el medio de transferencia de calor, preferiblemente el aire del medio ambiente. El aire caliente se hace pasar a un recipiente evaporador en donde él mismo evapora un agente reductor acuoso, preferiblemente amoníaco acuoso. El amoníaco evaporado es inyectado en la trayectoria de los gases de la combustión, en donde él mismo es efectivo para reducir el NOx. También se describen algunos aspectos de un sistema de control automático.
