Abstract

Una planta para un proceso de combustión. La planta tiene un horno (12) para calentar un material. Un quemador (16) configurado para quemar un combustible a base de carbono con un gas de oxidación para proporcionar una flama al horno. El gas de oxidación tiene al menos 80 por ciento en peso de oxígeno. El horno tiene una salida de escape (20, 22) que proporciona comunicación entre el horno y un conducto de gases (26). La salida de escape está configurada para remover un gas de escape que se produce durante la combustión del combustible a base de carbono del horno al conducto de gases. Una boquilla (30) ubicada en el conducto de gases está configurada para inyectar amoníaco en el conducto de gases y, por lo tanto, reducir la cantidad de emisiones de NOx en el gas de escape.
