Question 652Steam Plants - Assistant Engineer
70% to passAn excess pressure governor is a special type of control device which would normally be found on a _______________.
Aforced draft fan
Bmain circulator pump
Cturbine-driven feed pump
Dlow-pressure propulsion turbine
AI Explanation
The correct answer is C) turbine-driven feed pump. An excess pressure governor is a type of control device used to regulate the pressure in a turbine-driven feed pump, which is a key component in the steam propulsion system of a vessel. The excess pressure governor ensures that the feed pump does not generate excessive pressure in the boiler feed system, which could potentially damage the equipment. The other answer choices (A, B, and D) do not typically require an excess pressure governor, as they are not directly involved in the high-pressure boiler feed system where such a device would be necessary.
