Question 23Steam Plants - 1st Asst/Chief70% to pass
Fluctuations in the atomizing steam pressure at the burners could be caused by a/an _______________.
AI Explanation
The correct answer is D) malfunctioning steam trap in the atomizing steam system.
A malfunctioning steam trap in the atomizing steam system can cause fluctuations in the atomizing steam pressure at the burners. The steam trap is responsible for removing condensate from the atomizing steam line, and if it is not working properly, it can lead to pressure variations.
The other options are incorrect because:
A) A partially opened recirculating valve would not affect the atomizing steam pressure.
B) A partially closed atomizing fuel valve would impact the fuel flow, not the atomizing steam.
C) An incorrectly assembled air register would affect the air supply, not the atomizing steam.
