Abstract

INTERCAMBIADOR DE CALOR, EN PARTICULAR CALENTADOR DE VIENTO PARA ALTOS HORNOS, Y PROCEDIP8MIENTO CORRESPONDIENTE. CONSTA DE REVESTIMIENTO REFRACTARIO (3), CAPA AISLANTE (2) Y ENVOLVENTE DE ACERO (1). SE CARACTERIZA PORQUE LA CAPA AISLANTE, FORMADA POR LADRILLOS REFRACTARIOS DE ALTA RESISTENCIA FRENTE A ELECTROLITOS DE NITRATO O NITRITOS MODERADAMENTE ACIDOS, ESTA PROYECTADA DE MODO QUE EN CONDICIONES DE FUNCIONAMIENTO DEL INTERCAMBIADOR DE CALOR SE PUEDE AJUSTAR UNA TEMPERATURA DE LA ENVOLVENTE DE ACERO DE 20 A 60GC, PORQUE LA ENVOLVENTE ESTA FORMADA PORACERO DE CONSTRUCCION EXENTO DE CROMO CON UN CONTENIDO DE MOLIBDENO EN EL MARGEN DE 0,01 A 2 EN PESO QUE PRESENTA, BAJO UNA CARGA CAMBIANTE OSCILANTE DE BAJA FRECUENCIA, UNA ALTA RESISTENCIA FRENTE A LA CORROSION INTERCRISTA8LINA CON FISURACION POR TENSIONES DEBIDAS A NITRATO Y PORQUE LA TEMPERATURA DE LA CHAPA DE LA ENVOLVENTE SE CONTROLA ADICIONALMENTE POR MEDIO DE UN RIEGO CON AGUA ACOPLADO EN LA ZONA DESEADA. DE APLICACION A CALENTADORESDE VIENTO CON CUBA DE COMBUSTIBLE O CUBA DE PARRILLA EXTERIOR O INTERIOR Y A TUBERIAS COLECTORAS POSPUESTAS.
