What does condensation do in steam cycles?

• A. Converts steam to liquid water and returns it as boiler feedwater
• B. Increases steam temperature
• C. Keeps steam in gaseous state
• D. Converts liquid water into steam

Answer: (A)

Condensation is the phase change from steam back to liquid water. In a steam cycle, the exhaust steam from the turbine is cooled in a condenser and becomes condensate. That liquid water is collected and returned to the boiler as feedwater, often after a bit of treatment, so the cycle reuses water instead of constantly needing fresh makeup. This recycling saves energy because you’re heating already-condensed water rather than starting from ambient temperature to create new steam, and it helps maintain feedwater quality and system efficiency. So, the condensate returns as boiler feedwater, closing the loop.
