Question 640Steam Plants - Assistant Engineer

The correct answer is A) turbine-driven feed pump. An excess pressure governor is typically used on turbine-driven equipment, such as feed pumps, to prevent the turbine from exceeding its design pressure. This helps ensure the safe and reliable operation of the turbine-driven feed pump. The other options (B, C, and D) do not normally require an excess pressure governor, as they are not turbine-driven equipment. For example, a low-pressure propulsion turbine, a forced draft fan, and a main circulator pump are not typically equipped with an excess pressure governor.
