Abstract

E' descritta una turbina a vapore che elimina il trasferimento delle deformazioni dal cilindro interno ai complessi di palette fisse. Un collegamento imbullonato a due piani e una interfaccia a linguetta e scanalatura flottante liberamente, formata tra l'anello esterno dei complessi di palette fisse e il cilindro interno della turbina, forniscono il gioco necessario per eliminare la deformazione dei complessi di palette fissi, pur sopportandoli entro il complesso di turbina. L'anello esterno dei complessi di palette fisse può essere formato come un componente solidale o costituito da due parti saldate insieme. La presente invenzione permette anche alle palette rotanti della turbina di essere disposte in stretta vicinanza dell'anello esterno dei complessi di palette fisse e permette il posizionamento della guida del flusso sull'anello esterno poiché le deformazioni dovute alla variazione termica del cilindro interno vengono ora isolate.
