Combined cycle units with heat recovery steam generators (HRSG's) as well as combined cycle plants with fully-fired steam generators are operating reliably for decades. This paper reports that Siemens/KWU has built and on order a total of 30 GuD units. GuD (Gas und Dampf) meaning gas and steam, is the trade name for combined cycle power plants with HRSG's of Siemen/KWU. In addition Siemens/KWU has built or repowered 16 combined cycle plants with fully-fired steam generators, fluidized bed combustion or coal gasification systems. The experience gained, led also to the development of a variety of combined cycle arrangements which are based on simpler power plant concepts. The gas turbines for these plant concepts are equipped with a heat recovery steam generator or heat exchanger utilizing the gas turbine exhaust energy to provide additional main steam, reheat steam or feedwater heating for steam plants; thereby increasing their output and overall power plant efficiency.
