Abstract
Un impianto di condensazione (10) comprendo un collettore di ingresso (11) ricevente vapore e connesso ad una prima estremità di fasci di tubi (14) esternamente lambiti da aria per la condensazione almeno parziale in essi del vapore. Alla estremità opposta i tubi (14) sono raggruppati in almeno un collettore (15) di uscita del liquido condensato. Ogni collettore di uscita (15) è connesso da un condotto a sviluppo verticale (17) ad un elemento verticale (19, 20) di caduta a pioggia inferiormente sboccante in un serbatoio di raccolta (21). Al serbatoio di raccolta (21) è alimentato vapore dal collettore di ingresso (11) ,così che risalga l'elemento verticale (20) per il riscaldamento del liquido in caduta in esso.
