Abstract

CALDERA DE LECHO FLUIDIZADO CIRCULANTE (CFB) QUE AUMENTA LA CONFIABILIDAD Y MEJORA LA CAPACIDAD DE OPERACIÓN<br /> DE UNA CALDERA QUE COMPRENDE UNA CÁMARA DE REACCIÓN. UN LECHO FLUIDIZADO DE BURBUJAS (BFB) ESTÁ<br /> CONTENIDO DENTRO DE UN CERRAMIENTO EN LA PARTE INFERIOR DE LA CAMARA DE REACCIÓN Y CONTIENE UN INTERCAMBIADOR<br /> DE CALOR INCORPORADO EN EL LECHO (IBHX) QUE OCUPA PARTE DEL PISO DE LA CAMARA DE REACCIÓN. AL MENOS UNA<br /> VALVULA NO MECANICA, QUE INCLUYE UNA ABERTURA ENTRE EI CFB Y EL BFB Y MEDIOS FLUIDIZANTES CONTROLADOS<br /> INDEPENDIENTEMENTE UBICADOS AMBOS CORRIENTE ARRIBA Y CORRIENTE ABAJO DE LA ABERTURA, SE USAN PARA CONTROLAR<br /> LA TRANSFERENCIA DE CALOR AL IBHX CONTROLANDO LA DESCARGA DE SÓLIDOS DESDE EL BFB AL CFB. LA ALTURA DEL FONDO<br /> DE LA ABERTURA ESTA EN O POR ENCIMA DE LA ALTURA DEL MEDIO FLUIDIZANTE. UNA BARRERA DE CONTROL DE FLUJO PUEDE<br /> SER COLOCADA CORRIENTE ABAJO DE LA ABERTURA.<br />
