Abstract

CUERPO DE TURBINA DE VAPOR HP-MP QUE CONSTA DE UN ESTATOR INTERNO UNICO (57) QUE RODEA A LAS PARTES HP (2) Y MP (3) DEL ROTOR. EL ESTATOR INTERNO (57) DETERMINA CON EL ESTATOR EXTERNO (9) UNOS ELEMENTOS DE POSICIONAMIENTO AXIAL (11) DEL ESTATOR INTERNO (57) Y UNA PANTALLA TERMICA (10) EN UN ESPACIO INTERESTATORICO (19) BARRIDO POR EL VAPOR CAPTADO EN UNA DE LAS ULTIMAS FASES (25) DE LA VENA HP (6). LAS PARTES DEL ESTATOR INTERNO QUE RODEAN A LA TOTALIDAD DE LA VENA HP (6) Y LAS FASES CALIENTES DE LA VENA MP (8) SE CLIMATIZAN ASI DE FORMA OPTIMA, LO QUE PERMITE DISMINUIR EL GRADIENTE TERMICO SOPORTADO POR EL ESTATOR INTERNO (57) ASI COMO LA TEMPERATURA DE LOS BULONES DE LOS ESTATORS (57 Y 9).
