🔍 Key Concepts

• Steam turbine condenser operation in very cold seawater conditions • Effect of circulating water temperature and flow on condenser vacuum and condensate temperature • Meaning and consequences of condensate depression (subcooled condensate) on plant efficiency

💭 Think About

• Think about what happens to the condensate temperature when a large flow of very cold seawater passes through the condenser tubes. Is the condensate closer to, or farther below, saturation temperature? • How does over‑cooling the condensate (subcooling below saturation) affect the amount of heat that must be added later in the boiler and overall cycle efficiency? • Which answer choices correctly connect cold seawater, full cooling flow, vacuum level, and condensate temperature, and which ones mix these effects incorrectly?

✅ Before You Answer

• Compare saturation temperature at condenser pressure to the likely actual condensate temperature with very cold seawater and high flow • Decide whether this situation mainly causes higher vacuum, more condensate recirculation, condensate depression, or hotter condensate • Eliminate choices that claim an effect which contradicts: very cold seawater + full flow = maximum cooling of the condensate, not heating it up
