Abstract
An improved method of heating feedwater streams in a steam-to-steam reheating system for turbine generators is disclosed in which a drain cooler is located to receive the reheater drain and pass it in heat exchange relationship with the discharge of the highest pressure feedwater heater. By use of the drain cooler, heat rate improvement is effected on both single stage reheat plants and two-stage reheat plants. Cycle impairment from moisture carryover in the moisture separator/reheater is also reduced.
