ANALISI DEI PROCESSI

Turbina a gas a ciclo combinato (CCGT)

Molte centrali elettriche moderne funzionano a ciclo combinato. Nella prima fase, una turbina a gas produce elettricità. Il gas caldo spento dalla turbina a gas viene immesso in un sistema di caldaia termica convenzionale con un'altra turbina a vapore, ottenendo un'ottima efficienza complessiva. Nello schema precedente sono evidenziati i punti di misura di pH, Cond e DO.
