Etivity 2 Sistemi per l'energia e l'ambiente

Etivity 2 IMTV con reheat e spillamento

Dato lo schema d’impianto mostrato in figura calcolare:

• La potenza netta dell’impianto;
• Il rendimento elettrico netto dell’impianto.

Parametri operativi d’impianto

• Portata massica vapore (componente 3) = assumere le ultime due cifre della matricola (es. Matricola: 0001452 portata massica = 52 kg/s)
• Temperatura boiler (componente 3) = 550°C
• Pressione massima ingresso in turbina (componente 5) = 180 bar
• Temperatura reheat (componente giallo) = 550°C
• Pressione ingresso seconda turbina (componente 6) = 20 bar
• Pressione al condensatore (componente 9) = 0.05 bar
• Pressione degasatore (componente 1) = 20 bar

Terminata la simulazione siete pregati di inviarmi tramite piattaforma un report con i risultati ottenuti e lo screen del modello sviluppato.
