Question 48Steam Plants - Assistant Engineer
70% to passSalt water contamination of condensate could occur at which component?
AInter condenser
BDC heater
CAfter condenser
DFresh water evaporator
AI Explanation
The correct answer is D) Fresh water evaporator. In a marine steam plant, the fresh water evaporator is the component most vulnerable to salt water contamination of the condensate. This is because the evaporator uses the ship's seawater as the heat source to evaporate and distill fresh water from the condensate. If there is a leak in the evaporator tubes, salt water can contaminate the fresh water condensate. The other components listed (inter condenser, DC heater, after condenser) are not directly exposed to seawater, so they are less likely to allow salt water contamination of the condensate.
