Abstract

UN APARATO PARA EL TRATAMIENTO DE SUPERFICIES EN QUE UNA MEZCLA DE POLVO FLUIDIFICABLE QUE CONSISTE EN UN POLVO DE UN MATERIAL REFRACTARIO Y UN POLVO FORMADOR DE CAPAS SUPERFICIALES DE UN METAL O ALEACION O AMBAS SE FLUIDIFICA MEDIANTE UN GAS FLUIDIFICADOR SUMINISTRADO A TRAVES DE UN DISTRIBUIDOR DE GAS PARA FORMAR ENCIMA DEL DISTRIBUIDOR DE GAS UN LECHO FLUIDIFICADO EN QUE SE FORMA UNA CAPA SUPERFICIAL SOBRE EL MATERIAL A TRATAR MEDIANTE CALENTAMIENTO EN PRESENCIA DE UN HALURO. SE COLOCA UNA CAPA DE PARTICULAS GRUESAS ENTRE EL LECHO FLUIDIFICADO Y EL DISTRIBUIDOR DE GAS Y LAS PARTICULAS GRUESAS TIENEN UN DIAMETRO MEDIO, D-(M), COMO SE DEFINE A CONTINUACION: (1650V(MU)/PG(1/2 < D < 6,5D DONDE V: VELOCIDAD DEL GAS FLUIDIFICADOR (M/S); (MU): COEFICIENTE DE VISCOSIDAD DEL GAS FLUIDIFICADOR (KG/M (POR) S); P: DENSIDAD MEDIA DE LAS PARTICULAS GRUESAS (KG/M3); G: ACELERACION DE LA GRAVEDAD (9,8 M/S2); D: DIAMETRO MEDIO DE PARTICULA DEL POLVO QUE FORMA LA CAPA SUPERFICIAL (M). LA CAPA DE PARTICULAS GRUESAS PUEDE PREVENIR LA AGLOMERACION DE POLVOS DE LECHO FLUIDIFICADO O PROTEGER AL DISTRIBUIDOR DE GAS CONTRA LA EXPOSICION A LOS POLVOS Y GASES MUY REACTIVOS.
