Abstract

EL INVENTO SE REFIERE A UN METODO PARA CONTROLAR UNA PLANTA ENERGETICA PFBC EN CASO DE ALTERACIONES OPERATIVAS QUE AFECTAN A LA TURBINA ACCIONADA POR LA PLANTA, POR EJEMPLO, UNA CAIDA DE CARGA. LA PLANTA CONSTA DE UN LECHO (12) ENCERRADO DENTRO DE UN VASO DE PRESION (10) Y RODEADO POR AIRE DE COMBUSTION A PRESION. EL RECIPIENTE DEL LECHO CONSTA DE UN LECHO (22) DE MATERIAL PARTICULADO FLUIDIFICABLE. LA PLANTA CONSTA ADEMAS DE UNA TURBINA-COMPRESOR DE GAS (34,38,48) ACCIONADA POR GASES DE COMBUSTION PROCEDENTES DEL VASO DEL LECHO (12). EN UN CONDUCTO DE GAS CALIENTE (32) SITUADO ENTRE EL LECHO (12) Y UNA TURBINA (34) HAY UNA PRIMERA VALVULA DE CIERRE (54), MIENTRAS QUE EN UN CONDUCTO (50) SITUADO ENTRE EL COMPRESOR (48) Y EL LECHO (12) VA UNA SEGUNDA VALVULA DE CIERRE (58). ENTRE AMBOS CONDUCTOS (32,50) HAY UN CONDUCTO DE CORTOCIRCUITO (62) CON UNA TERCERA VALVULA DE CIERRE (64). EN CASO DE QUE TENGA LUGAR UNA ALTERACION OPERATIVA, LA UNIDAD DE TURBINA-COMPRESOR (34,38,48) SE DESCONECTA DELLECHO (12) Y EL RECIPIENTE DE PRESION (10), RESPECTIVAMENTE, POR EL CIERRE DE LA PRIMERA Y LA SEGUNDA VALVULAS (54,58) EN LOS CONDUCTOS (32,50) ENTRE EL LECHO (12) Y LA TURBINA (34) Y ENTRE EL COMPRESOR (48) Y EL RECIPIENTE DE PRESION (10), RESPECTIVAMENTE. AL MISMO TIEMPO, SE ABRE LA VALVULA DE DERIVACION (64) EN EL CONDUCTO DE CORTOCIRCUITO (62). EN EL CASO DE QUE LA ALTERACION REQUIERA EL CIERRE DE LA PLANTA, LOS GASES DE COMBUSTION DEL LECHO (12) SE ENVIAN A LA ATMOSFERA A TRAVES DE UN CONDUCTO (68) Y UNA VALVULA (72) DE VERTIDO. AL EXPULSAR LOS GASES DE COMBUSTION, SE INYECTA EN EL CONDUCTO (68) AGUA DE REFRIGERACION ANTES DE LA VALVULA DE VERTIDO (72), DE FORMA QUE LOS GASES SE ENFRIAN ANTES DE LLEGAR A LA MISMA. EL INVENTO SE REFIERE TAMBIEN A UNA PLANTA CON UN DISPOSITIVO (70) PARA INYECTAR AGUA DE REFRIGERACION EN UN CONDUCTO (68) SITUADO ANTES DE UNA VALVULA DE VERTIDO (72) PARA REFRIGERAR LOS GASES CALIENTES DE COMBUSTION DEL LECHO (12) ANTES DE QUE ALCANCEN A LA VALVULA (72).
