Which phase is the last phase in the basic steam cycle?

• A. Boiler phase.
• B. Feed phase.
• C. Turbine phase.
• D. Condensate phase.

Answer: (B)

In a basic steam cycle, water completes four stages: it’s heated in the boiler to become steam, the steam expands through the turbine doing work, it’s condensed back into liquid in the condenser, and then that condensate is pumped by the feedwater pump back up to boiler pressure to restart the cycle. The action that closes the loop and returns water to the boiler is the feed phase, making it the last phase before the cycle repeats. The boiler is the start, the turbine is in the middle, and the condenser comes before the pump, so the feed phase is the final step.
