Question 74Steam Plants - 1st Asst/Chief70% to pass
A leaky fuel oil heater relief valve could be indicated by an increase in the _______________.
AI Explanation
The correct answer is B) discharge piping temperature.
A leaky fuel oil heater relief valve would allow hot fuel oil to be discharged back into the fuel oil piping system, which would cause an increase in the discharge piping temperature. This is the primary indication that the fuel oil heater relief valve is leaking.
The other answer choices are incorrect because:
A) An increase in sludge tank level would not be a direct indication of a leaky fuel oil heater relief valve.
C) An increase in the contaminated drain tank level could indicate a different issue, such as a leak in the fuel oil system, but not specifically a leaky fuel oil heater relief valve.
D) An increase in fuel oil service pump pressure would not be a reliable indicator of a leaky fuel oil heater relief valve.
