Abstract
A method and apparatus for improving a steam-to-steam reheat system employing the drain cooler concept in a steam turbine is disclosed. The large and complicated drain receiver of the prior art is eliminated, thereby removing a source of unreliable performance and internal flooding of MSR bundle drains. A drain cooler is utilized and its utility enhanced by installing a condensate bypass line with control valve which is used to adjust the condensing capability of the drain cooler in order to optimize the amount of scavenging steam for varying load conditions, thereby achieving an improvement in heat rate reduction.
