Abstract

METODO Y MEDIOS PARA LA REGULACION DEL FUNCIONAMIENTO DE UN REACTOR DE LECHO FLUIDIZADO, CIRCULANTE. CONSISTE EN REFRIGERAR LOS SOLIDOS MEDIANTE LA DIRECCION DE LOS SOLIDOS QUE TIENEN QUE SER DEVUELTOS AL REACTOR, A TRAVES DE TUBERIAS DE RETORNO, DE LOS CUALES, ALGUNAS, ESTAN REFRIGERADAS Y DONDE EL EFECTO DESEADO DE REFRIGERACION ES LLEVADO A CABO MEDIANTE LA REGULACION DE LAS CANTIDADES DE SOLIDOS QUE FLUYEN A TRAVES DE LAS TUBERIAS DE RETORNO. LOS MEDIOS COMPRENDEN UNA PLURALIDAD DE TUBERIAS DE RETORNO FUNCIONANDO PARALELAMENTE (205, 206), DE LAS CUALES UNAS (206) ESTAN PROVISTAS CON SUPERFICIES DE TERMOTRANSFERENCIA (215) Y DONDE EN ALGUNAS DE ELLAS (210) EXISTEN DISPUESTOS MEDIOS PARA LA REGULACION DE LA CANTIDAD DE LOS SOLIDOS QUE FLUYEN A TRAVES DE ELLAS.
