Selecting the initial steam temperatures in starting combined-cycle plants in compliance with the conditions of heating the high-pressure steam superheater outlet headers
Tóm tắt
Results from an analysis of permissible initial steam temperatures and heating rates of the outlet headers of high-pressure steam superheaters and the steam lines of combined-cycle plants at which their cyclic strength is ensured are presented. A procedure is proposed using which startup assignment schedules for different thermal states can be constructed proceeding from the heating rates and initial steam temperatures selected depending on the initial temperature state of the high-pressure steam superheaters’ outlet headers.
