Steam exhaa*^ 36S ptlg from the high-pressure u*; It returns to a reheat boiler where l&S perature is raised back up to From here U enters the Imermediate^i eure clement of the turbine. The pressure turbine has an inlet press^ about 40 psig and la of. doubla-fiosr smiciion. The second turbine designed (or it a XLOOO-kw one slated for Dow Cfcto^L - Co.
