Question 397Steam Plants - 1st Asst/Chief70% to pass
An excess pressure governor would normally be used on a _______________.
AI Explanation
The correct answer is B) turbine-driven feed pump.
An excess pressure governor is typically used on turbine-driven feed pumps to prevent overpressurization of the boiler feed system. The governor monitors the discharge pressure of the feed pump and will automatically adjust the steam supply to the turbine to maintain the desired feed pressure, preventing damage to the system from excessive pressure.
The other answer choices are incorrect because low-pressure propulsion turbines, forced draft fans, and main circulator pumps do not typically require an excess pressure governor. These components are not as sensitive to overpressure conditions as the turbine-driven feed pump, which supplies high-pressure water to the boiler.
