Abstract

UN METODO DE OPERAR UN HORNO REGENERADOR DE VIDRIO PARA FUNDIR VIDRIO PARA LA FABRICACION DE ARTICULOS DE VIDRIO, QUE MINIMIZA LAS EMISIONES DE NOX EN LOS GASES RESIDUALES QUE SALEN DEL HORNO, TENIENDO EL HORNO REGENERADORES SELLADOS LOS CUALES ACTUAN COMO INTERCAMBIADORES DE CALOR, EL METODO CONSISTE EN SUMINISTRAR COMBUSTIBLE EN EXCESO CON RESPECTO AL QUE SE REQUIERE PARA COMBUSTION ESTEQUIOMETRICA PARA ASEGURAR QUE SE OBTIENE VIDRIO DE LA CALIDAD REQUERIDA EN LA PROPORCION DE PRODUCCION REQUERIDA, Y QUE LOS GASES RESIDUALES QUE SALEN DEL HORNO A TRAVES DE LOS REGENERADORES CONTIENEN MATERIAL COMBUSTIBLE, Y LA REACCION DE DICHO MATERIAL COMBUSTIBLE CON SUFICIENTE AIRE PARA ASEGURAR QUE LOS GASES RESIDUALES QUE SALEN A LA ATMOSFERA CONTIENEN NIVELES PERMISIBLES DE MATERIAL COMBUSTIBLE Y CONTIENEN NIVELES PERMISIBLES DE NOX. ALTERNATIVAMENTE, EL HORNO PUEDE OPERAR EN CONDICIONES SUSTANCIALMENTE ESTEQUIOMETRICAS Y SE SUMINISTRA COMBUSTIBLE A LOS GASES RESIDUALES MIENTRAS QUE DEJAN LA CAMARADE FUSION. LA INVENCION TAMBIEN SE REFIERE A UN HORNO REGENERADOR DE VIDRIO PARA USAR EN EL METODO. LA INVENCION ADEMAS PROPORCIONA UN METODO DE REDUCIR LAS EMISIONES DE CO EN LOS GASES RESIDUALES QUE SALEN DEL HORNO DE FUEGO CRUZADO, PARA FUSION DE VIDRIO, PARA LA FABRICACION DE ARTICULOS DE VIDRIO, TENIENDO EL HORNO REGENERADORES SELLADOS LOS CUALES ACTUAN COMO INTERCAMBIADORES DE CALOR, COMPRENDIENDO EL METODO ELIMINAR CO DE LOS GASES RESIDUALES EN EL GENERADOR POR COMBUSTION DE CO CON ALREDEDOR DE 8% DE EXCESO DE AIRE, BASADO SOBRE EL AIRE DE COMBUSTION PARA EL COMBUSTIBLE SUMINISTRADO, A UNA TEMPERATURA MAYOR DE 650 C.
