Question 734Steam Plants - Assistant Engineer70% to pass
Which of the following systems can normally be supplied by auxiliary exhaust steam?
AI Explanation
The correct answer is D) Low-pressure evaporator.
Auxiliary exhaust steam is often used to supply low-pressure evaporators on ships. Evaporators use heat from the auxiliary exhaust steam to evaporate water, producing freshwater for the vessel's use. This is an efficient way to utilize the waste heat from the auxiliary engines.
The other options are incorrect because air ejectors, main feed pumps, and boiler steam atomizers typically require higher-pressure steam, which would not be supplied by the auxiliary exhaust steam system.
