... on the thermodynamic cycle is completed. The results show that the same turbine could be used in different systems with power outputs varying between 17 and 112 kW, suggesting the potential of matching the same turbine to multiple heat sources by tailoring the working fluid selected. This further implies that the same...

...S. Can Gülen; Chris Hall This paper describes a gas turbine combined cycle (GTCC) power plant system, which addresses the three key design challenges of postcombustion CO 2 capture from the stack gas of a GTCC power plant using aqueous amine-based scrubbing method by offering the following: (i) low...

... Power Turbines Co- generation Many steam turbines used for power generation are generally operated to maintain a rated output (typically 95% of the maximum output). However, there has been a recent increase in cases of load-following operation. Recently introduced ultrasupercritical (USC...
