WebNew Approach to Energy Conversion Technology. Bahman Zohuri, in Molten Salt Reactors and Integrated Molten Salt Reactors, 2024. 3.7 Combined-Cycle Gas Power Plant. A combined-cycle gas turbine (CCGT) power plant is essentially an electrical power plant in which a gas turbine and a steam turbine are used in combination to achieve greater … WebThe “thermodynamic quality” of air (or any other gas) cycles is rather poor. Actually, as shown in Fig. 1.3, the efficiency of a gas cycle is negative up to about Tmax < 250°C. Even at 400°C, the simple cycle efficiency hardly reaches 8%. The recuperated cycle efficiency is higher, but still remains relatively low.
