Abstract

TURBINA DE VAPOR CON ADMISION AXIAL.COMPRENDE UN APANTALLADO DEL EJE (6) QUE RODEA AL EJE (5) Y QUE ESTA UNIDO RADIALMENTE CON LOS EXTREMOS INTERNOS DE LOS ALABES DE GUIA (7) O (7K) DE CADA UNA DE LAS PRIMERAS CORONAS DE ALABES DE GUIA DE LOS DOS FLUJOS DE LA TURBINA, Y A SU VEZ (7) Y (7K) ESTAN INSERTADOS EN LOS SOPORTES (3) O (3K). EN EL APANTALLADO DEL EJE (6) SE HAN DISPUESTO CUATRO TOBERAS (8) HOMOGENEAMENTE DISTRIBUIDAS SOBRE LA PERIFERIA QUE DESEMBOCAN TANGENCIALMENTE EN EL CANAL ANULAR (4) CONSTITUIDO ENTRE EL EJE (5) Y EL APANTALLADO (6), VISTOEN EL SENTIDO DE ROTACION (9) DEL EJE (5). EN EL CANAL (4) SE FORMA UNA CORRIENTE EN ESPIRAL (10) QUE SE SUBDIVIDE EN OTRAS DOS (11) Y (11K) QUE FLUYEN A LO LARGO DEL EJE (5) HASTA LOS ALABES MOVILES (12) Y (12K) DE CADA UNA DE LAS CORONAS DE ALABES MOVILES DE AMBOS FLUJOS. LA CORRIENTE MASICA DEL VAPOR QUE LLEGA AL CANAL ANULAR (4) SUPONE APROXIMADAMENTE UN 3 DE CORRIENTE MASICA TOTAL DE VAPOR ENVIADA A TRAVES DEL CANAL DE ADMISION (2).
