🔍 Key Concepts

• Deaerating feed water tank (DC heater) operation during load changes • Relationship between boiler water level, condensate return, and make‑up feed • How recirculation of main condensate affects level in the deaerating tank

💭 Think About

• As the plant goes from maneuvering to sea speed, what happens to steam demand and how does that change the flow of condensate and make‑up water? • For each option, think: does this condition reduce the net inflow to the DC heater, increase outflow, or temporarily trap water somewhere else in the system? • Could more than one of these conditions reasonably contribute to a low level in the deaerating tank during a power increase?

✅ Before You Answer

• For each choice, trace the water path: boiler → steam → condenser → condensate system → DC heater → boiler, and decide if DC heater level goes up or down. • Check which conditions would withhold water in another part of the system (e.g., in the boilers or recirculation line) instead of allowing it to accumulate in the DC heater. • Verify whether a power increase tends to amplify the effect of each listed condition on DC heater level, rather than cancel it.

Question 1 of 20

Which condition could cause a low level in the deaerating feed water tank (DC heater) as the vessel is increasing from maneuvering to sea speed?

Maintaining the water levels of both boilers excessively high

Excessive recirculation of main condensate

Insufficient flow of make-up feed to the condenser

All of the above
