Abstract
Se proporciona un sistema de combustión para proporcionar la reducción de emisiones. El sistema de combustión incluye una fuente de agente reductor selectivo, acuoso para suministrar un agente reductor selectivo, acuoso, un atomizador (327, 427) acoplado directamente en comunicación fluida con la fuente de agente reductor selectivo, acuoso, el atomizador recibe y atomiza el agente reductor, selectivo que es suministrado desde la fuente de agente reductor selectivo, acuoso. El sistema de combustión también incluye una zona de temperatura (118, 248, 318, 448) definida dentro del sistema de combustión, en donde el atomizador inyecta directamente gotitas de agente reductor selectivo dentro de la corriente de transporte del gas de chimenea que fluye dentro de la zona de temperatura.
