Question 131Steam Plants - QMED70% to pass
What is the normal destination of steam exiting a main feed pump drive turbine?
AI Explanation
The correct answer is D) Dearating feed tank via the auxiliary exhaust steam line.
The main feed pump drive turbine exhausts steam to the dearating feed tank via the auxiliary exhaust steam line. This allows the steam to be used to heat and deaerate the feed water, improving its quality before it enters the boiler.
The other options are incorrect because:
A) The SSTG (ship's service turbine generator) would not be the destination for the main feed pump drive turbine exhaust.
B) The main condenser is not the correct destination for the auxiliary exhaust steam.
C) The main feed pump discharge line does not carry the auxiliary exhaust steam to the dearating feed tank.
