What is the only water used in the boiler.
What is feed water?
A system that is used to create combustion in the boiler.
What is the Fuel System?
Tubes that direct feed water from the steam drum to the headers.
What are Downcomers?
The type of heat exchanger that the Main Condenser uses to condense steam.
What is crossflow?
Means to reduces the speed two times.
What is double reduction?
Used to remove excess chemicals from the feed water at all times while the boiler in online.
What is continuous blowdown?
Used to lubricate the main engine bearings.
What is Lube Oil?
A big header that distributes water to the generating tubes.
What is the water drum?
The primary way to supply seawater to the main condenser when under 12 knots.
What is Main Circ Pump?
The orientation the gear teeth in a "V" pattern to reduce axial thrust.
What is Double helical?
The piece of equipment that produces feed water when underway.
What is the Evap?
Used as a cooling medium for the stern tube shaft seal.
What is sea water?
Located in the steam drum to remove water by a rapid change in direction.
What is the secondary separator (dry box)?
The heat sources of the main condenser.
What are Make up feed, Aux exhaust, and Fresh water drain collecting tank?
An instrument used to view the flow of lube oil in the main engine.
What are Sight Flow Indicators?
Is caused in the boiler when there is an unbalance of chemicals in the feed water.

6574
What is the number of tubes in the main condenser?
An installed instrument used to determine the position of the HP and LP Turbine Rotors.
What are Rotor Position Indicators?
A chemical injected into the DFT to treat condensate.
What is EDTA?
The system that is supplied to batch treat the Lube Oil settling tanks.
What is 150 Wet?
