Consider a steam plant with a single reheat and a single open feedwater heater that takes extraction from the cold reheat line. Sketch carefully coordinated and labeled T-s and flow diagrams.
If the throttle is at 1000/F and 3000psia, the condenser is at 1 psia, and reheat is to 1000/F at 400 psia, what is the extraction mass fraction, the heat rate, and the thermal efficiency? The turbine efficiency is 89%. Neglect pump work
