Question 252Steam Plants - 1st Asst/Chief70% to pass
While maneuvering out of port, you answer a stop bell. You notice a lot of steam coming out of the gland exhaust condenser vent, in addition to the main condenser hotwell level being low. For this condition you should _______________.
AI Explanation
The correct answer is B) manually recirculate condensate and add some makeup feed.
The explanation is as follows:
1. Confirm which answer is correct: B) manually recirculate condensate and add some makeup feed is the correct answer.
2. Explanation of the reasoning: The symptoms of a lot of steam coming out of the gland exhaust condenser vent and a low main condenser hotwell level indicate a problem with the condensate system. To address this issue, the proper response is to manually recirculate the condensate and add some makeup feed to the system. This helps to restore the proper condensate level and maintain the heat balance in the system.
3. Why the other options are incorrect:
A) Speeding up the condensate pump would not resolve the issue of a low condensate level.
C) Decreasing the gland sealing steam pressure would not address the root cause of the low condensate level.
D) Increasing the steam pressure to the air ejectors would not directly address the low condensate level problem.
4. Concise summary: The correct answer is to manually recirculate the condensate and add some makeup feed to address the symptoms of a low main condenser hotwell level and excessive steam coming from the gland exhaust condenser vent.
