Abstract

GENERADOR DE VAPOR PIRAMIDAL DE PRESION GRADUAL. CON CARGA EXTRAORDINARIAMENTE BAJA LA UNIDAD OPERA A PRESION SUBCRITICA. EL AGUA DE ALIMENTACION ES CONTROLADA PARA MANTENER UN NIVEL DE AGUA (84) EN EL CALDERIN (26). EL AGUA SE MEZCLA CON EL FLUJO DE RECIRCULACION EN EL COLECTOR (24), PASANDO A TRAVES DE LA BOMBA (34) Y ASCENDIENDO POR LOS TUBOS (14), RAYADOS ANTERIORMENTE. LA MEZCLA VAPOR-AUGA PRODUCIDA ES LLEVADA AL CALDERIN, DONDE SE PONE EN RECIRCULACION EL AGUA NO EVAPORADA. CON BAJA CARGA NORMAL LA UNIDAD OPERA COMO UN SISTEMA PIRAMIDAL SUBCRITICO. EL AGUA DE ALIMENTACION, PROCEDENTE DEL CONDUCTO (22) PASA A TRAVES O ALREDEDOR DE LA BOMBA (34) Y ASCIENDE POR LOS TUBOS (14). EL FLUJO ES CONTROLADO PARA OBTENER VAPOR LIGERAMENTE RECALENTADO, EL CUAL PASA AL SEPARADOR (26) Y SIGUE HACIA LOS RECALENTADORES. CASO DE DESCARGAR ALGO DE AGUA EN EL CALDERIN ES EVACUADA POR EL TUBO (86) AL C.A.A. EN LOS REGIMENES ALTOS LA UNIDAD OPERA A PRESION SUPERCRITICA EN EL MODO PIRAMIDAL.
