Abstract

PROCEDIMIENTO DE FUNCIONAMIENTO DE UN LECHO FLUIDIZADO, EN EL QUE LAS PARTICULAS DEL LECHO TIENEN UN NUMERO DE REYNOLDS MENOR QUE 20. CONSISTE EN PONER UN FLUIDO CRIOGENICO EN CONTACTO INDIRECTO CON EL LECHO; PERMITIR QUE EL LIQUIDO SE VAPORICE EN LA SUPERFICIE DE CONTACTO INDIRECTO, ENFRIANDOSE; EMPLEAR EL VAPOR DE LA OPERACION ANTERIOR PARA FLUIDIZAR; Y ENFRIAR EL LECHO DESDE LA TEMPERATURA AMBIENTE HASTA LA CRIOGENICA; CAMBIANDO CONTINUA O ESCALONADAMENTE EL CAUDAL MASIVO FLUIDIZANTE MINIMO DE VAPOR A MEDIDA QUE CAMBIA LA TEMPERATURA DEL LECHO. ESTOS LECHOS FLUIDIZADOS TIENEN APLICACIONES PARA CALENTAMIENTO Y ENFRIAMIENTO DE MATERIALES.
