Exergy analysis and economic evaluation of the steam
Jun 27 2017 · In order to effectively utilize the steam superheat of ultra‐supercritical power plants a regenerative turbine (RT) system was proposed. In the RT system a portion of the high‐pressure turbine exhaust steam is sent to an extra turbine termed as RT and the extracted steam of several regenerative heaters (RHs) would be extracted from the RT instead of the intermediate‐pressure turbine.
