Steam is used for propulsion and also to supply power generation turbines, forced draft blowers, and what other system?

• A. Distilling plants
• B. Air conditioning
• C. Lubrication system
• D. Fuel oil heaters

Answer: (A)

Steam on a ship serves several roles beyond propulsion: it also drives the turbines that generate electrical power, powers the forced-draft blowers that feed air for boiler combustion, and heats distilling plants that convert seawater into fresh water. Distilling plants rely on heat from steam to evaporate seawater; the resulting vapor condenses into potable water for the crew and ship operations. This use is a standard, direct application of steam because it efficiently provides the necessary heat without needing a separate heat source.
