Question 153Steam Plants - 1st Asst/Chief70% to pass
On a steam vessel with two high pressure boilers, one suspects a superheater leak. How would you determine which boiler may be leaking and what would be the indication(s)?
AI Explanation
The correct answer is B.
Increased boiler make-up water consumption, increased opening of that boiler's feed water valve, and/or unusual control signals to that boiler's feed water valve would be the primary indications of a superheater leak in one of the boilers on a steam vessel with two high pressure boilers.
This is because a superheater leak would result in increased water loss from the affected boiler, requiring more make-up water and increased feed water flow to maintain the proper water level and pressure. The other options, while potentially related signs, are not as direct or reliable indicators of which specific boiler is experiencing the leak.
