Design Tomorrow’s Combined Cycle Power Plant Using Previous Lessons Learned
Today’s construction boom in the combined cycle/cogeneration sector is great news for suppliers of gas turbines (GTs), heat recovery steam generators (HRSGs), and engineer-procure-construct (EPC) services. But before this boom advances from artist’s sketches (Figure 1) to first fires, the designers of all those next-generation combined cycles should pause to reflect on the lessons learned […]
