Abstract

Una turbina de vapor (10) incluye un alojamiento externo (22) y un alojamiento interno (12) dispuestos dentro del alojamiento externo; el alojamiento interno está dividido horizontalmente en una dirección axial (16) hacia una porción superior del alojamiento interno (24) y una porción inferior del alojamiento interno (26); la turbina de vapor también incluye un escalón de impulso (40) dispuesto dentro del alojamiento interno (12), en donde el alojamiento interno está configurado para proporcionar total admisión de arco de un fluido al escalón de impulso (40); la turbina de vapor además incluye por lo menos un escalón de reacción (42) que tiene múltiples álabes; el por lo menos un escalón de reacción está integrado dentro del alojamiento interno para limitar la presión ejercida en el alojamiento externo.
