Abstract

TORRE DE COMPARTIMIENTOS DE UN TANQUE DE COMBUSTIBLE (18) PARA ACIDO FOSFORICO Y QUE PUEDE OPERAR A PRESIONES MUY ELEVADAS YA QUE NO EMPLEA VAPORES EN LA OPERACION DE LA ETAPA DE CONVERSION (40). SIENDO CAPAZ DE OPERAR A PRESIONES MUY ELEVADAS, LA TORRE PRESENTA MUY BAJAS VELOCIDADES DE CALENTAMIENTO DEL SISTEMA TENIENDO ASI UNA ELEVADA EFICIENCIA EN LA OPERACION. LA OPERACION CON PRESIONES MUY ELEVADAS TAMBIEN SE TRADUCE EN UNA MEJOR DENSIDAD DE ENERGIA EN LOS COMPARTIMIENTOS DE COMBUSTIBLE Y EN UN COSTE REDUCIDO. LA TORRE (18) SE ENFRIA MEDIANTE UNA MEZCLA REFRIGERANTE DE AIRE Y GOTAS DE AGUA TENIENDO UNA SALIDA CATODO Y UNA NIEBLA DE AGUA INYECTADA. DURANTE LA OPERACION DE ENFRIAMIENTO, LAS GOTAS DE AGUA EN LA MEZCLA REFRIGERANTE SE VAPORIZAN EN LOS CONDUCTOS DE REFRIGERACION (24) DE LA TORRE. LA SALIDA DESDE EL SISTEMA DE REFRIGERACION DESPUES DE CALENTARSE SE LLEVA ENTONCES A UN CONVERTIDOR AUTOMATICO (40) DONDE REACCIONA CON COMBUSTIBLE NUEVO PARA PRODUCIR HIDROGENO PARA LA OPERACION DE LOS COMPARTIMIENTOS DE COMBUSTIBLE EN LA TORRE (189. EL CONVERTIDOR (40) NO REQUIERE UN QUEMADOR INDEPENDIENTE PARA OPERAR PROPIAMENTE.
