Abstract

Un sistema di turbina a vapore avente una camera di distribuzione del vapore accoppiata in condizioni operative con una turbina a vapore comprende una apparecchiatura per il riscaldamento regolato della camera di distribuzione del vapore per ridurre le sollecitazioni termiche. Una linea di perdita del vapore accoppiata alla camera di distribuzione del vapore comprende una valvola di regolazione di portata per regolare la portata di vapore della camera di distribuzione del vapore attraverso la linea di perdita, e una unità di comando è accoppiata in condizioni di comando con la valvola di strozzamento e la valvola di regolazione della portata per regolare la portata di vapore da e per la camera di distribuzione del vapore per effettuare un riscaldamento controllato della camera di distribuzione del vapore. L'unità di comando è collegata in modo da ricevere i segnali provenienti da un sensore di temperatura ed è sensibile ai segnali per regolare il riscaldamento della camera di distribuzione del vapore.
