🔍 Key Concepts

• Steam plant operation in a gas-burning (boiler/turbine) system • Normal handling of excess steam when demand from the machinery drops • How conservation of water and energy is managed in a closed steam cycle

💭 Think About

• In a typical marine steam plant, is the system generally open to the atmosphere, or is it a closed cycle that tries to recover water and heat? • If steam demand suddenly decreases, what equipment in the system is designed to receive or handle that extra steam safely? • Which of the options would be most consistent with protecting both the machinery and maintaining the boiler water inventory?

✅ Before You Answer

• Check how a closed steam cycle (boiler → turbine → condenser → feed system → boiler) normally works on a ship. • Identify which option represents equipment that is actually part of the steam cycle and not something unrealistic or unsafe. • Eliminate any options that would waste feedwater or violate normal shipboard safety and environmental practices.
