Advances in Combined-Cycle Plant Design and Construction: 2018 State-of-the-Art Plants with Advanced-Class Gas Turbines
This report describes recent advanced natural gas turbine combined-cycle design and construction features and compares them with those of the previous generation F-Class combined cycle.
During power plant startup and shutdown, condensation occurs in the high-pressure superheaters and reheaters of heat recovery steam generators, and many drain systems inadequately remove the condensate, resulting in severe fatigue and cracking on superheaters, reheaters, headers, and piping. This report is intended to help steam generators owners to evaluate, maintain, and retrofit ineffective drain […]
Increasing renewable generation has forced combined-cycle and simple-cycle fossil plants to start more frequently, operate over a greater load range, and provide load-balancing. This report updates a 2014 report with two additional plant case studies on flexible operation strategies and technologies.
