Abstract

Un sistema di generazione di vapor acqueo, particolarmente adatto per funzionamento ciclico sotto carico e funzionamento ciclico inserito/disinserito e due operazioni di cambio, in cui il calore accumulato da fluidi e metalli in un percorso principale del flusso del fluido, viene utilizzato per eliminare l'urto termico dell'apparecchiatura e conseguenti guasti dovuti a sollecitazioni per fatica.
