Abstract

resumo “sistema” trata-se de uma turbina a vapor (10) que inclui um invólucro exterior (22) e um invólucro interior (12) disposto no invólucro exterior. o invólucro interior é dividido horizontalmente em uma direção axial (16) em uma porção de invólucro interior superior (24) e uma porção de invólucro interior inferior (26). a turbina a vapor inclui também uma fase de impulso (40) disposta no invólucro interior (12) em que o invólucro interior é configurado para fornecer uma admissão de arco completo de um fluido para a fase de impulso (40). a turbina a vapor inclui adicionalmente pelo menos uma fase de reação (42) que tem múltiplas pás. a pelo menos uma fase de reação é integrada no invólucro interior para limitar a pressão exercida no invólucro exterior.
