Abstract

DISPOSITIVO PARA LA EXTINCION CON AGUA CALIENTE DE CENIZAS VOLANTES QUE CONTIENEN CAL LIBRE ANHIDRA. DESPUES DE ALMACENAR LAS CENIZS EN UN SILO (1), SE INTRODUCEN EN UNA SERIE DE AUTOCLAVES, A TRAVES DE UNAS TOBERAS QUE PRESENTAN UN CIERRE (6) Y UN CONDUCTO DE DESAIREACION (7) COMUNICADO CON LA PARTE SUPERIOR DEL SILO. PARA CALENTAR LAS CENIZAS SE INTRODUCE EN EL AUTOCLAVE QUE SE HA LLENADO DE VAPOR PROCEDENTE DEL AUTOCLAVE ANTERIOR, QUE ESTA EN PROCESO DE EXTINCION, A TRAVES DE UN CONDUCTO (8) Y DE UNA VALVULA (9). SE CIERRAN EL AUTOCLAVE Y LA VALVULA Y SE INTRODUCE EN EL MISMO AGUA CALIENTE A TRAVES DE UNOS PULVERIZADORES (13).
