Question 252Steam Plants - Assistant Engineer
70% to passIn the event of a failure of the pneumatic control system, a multi-element feed water regulator is designed to operate as a _______________.
Aconstant-volume feed water regulator
Bconstant-pressure regulator
Cthermo-hydraulic feed water regulator
Dmanually controlled feed water regulator
AI Explanation
The correct answer is D) manually controlled feed water regulator. In the event of a failure of the pneumatic control system, a multi-element feed water regulator is designed to operate as a manually controlled feed water regulator. This means that the feed water regulation would need to be adjusted manually by the operator, rather than automatically by the pneumatic control system. The other options, such as a constant-volume or constant-pressure regulator, would not be the appropriate design for a system that requires manual control in the case of a pneumatic failure.
