The steam at the high-pressure turbine inlet is at 1500 psia and 800 o F and the effluent is saturated vapor. The steam is reheated to 750 o F before it enters the low pressure turbine where the steam is let down to 20 psia.

Get a QuoteBoiler and Condenser Pressures – Rankine Cycle. As in the Carnot, Otto and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature at which energy is rejected decreases. This is the common feature of all thermodynamic cycles.
