Abstract

INSTALACION DE CONTROL PARA TURBINAS DE VAPOR CON UNA ETAPA DE ALTA PRESION Y, AL MENOS, OTRA ETAPA DE MENOR PRESION, QUE FUNCIONAN CONJUNTAMENTE CON CALDERAS DE PRESION CONSTANTE O CORREDIZA CONSTA DE UNA SERIE DE VALVULAS QUE, COMANDADAS POR UNOS LAZOS DE CONTROL, REGULAN LA ENTRADA O LA DERIVACION DEL VAPOR A TRAVES DE LAS TURBINAS. EL VAPOR GENERADO EN LA CALDERA (1) PUEDE DIRIGIRSE A LA TURBINA DE ALTA PRESION (3) A TRAVES DE LA VALVULA DE CONTROL DE ALTA PRESION (11), O DERIVARSE, A TRAVES DE LA VALVULA DE PASO DERIVADO (12) Y DE LA ESTACION DE RECALENTAMIENTO 813); POSTERIORMENTE DICHO VAPOR, A MENOR PRESION, PUEDE ENVIARSE, BIEN A LAS TURBINAS DE PRESION INTERMEDIA (4) Y DE BAJA PRESION (5), A TRAVES DE LA VALVULA INTERCEPTORA (16), O BIEN DIRIGIRSE DIRECTAMENTE AL CONDENSADOR A TRAVES DE LA VALVULA DE PASO DERIVADO DE BAJA PRESION (21).
