Question 715Steam Plants - Assistant Engineer

You are correct, the answer is A) turbo-generator. A constant speed hydraulic governor would most likely be installed on a turbo-generator to maintain a constant rotational speed, which is essential for the generator to produce consistent electrical output. Hydraulic governors are commonly used to regulate the speed of turbine-driven equipment like generators, as they can precisely control the flow of the working fluid (typically oil or water) to the turbine. The other options are less likely candidates for a constant speed hydraulic governor. Main condensate pumps, main propulsion turbines, and main feed pumps are typically driven by electric motors or variable-speed drives, which do not require the precise speed regulation provided by a hydraulic governor.
