Question 130Steam Plants - QMED

The correct answer is D) turbine-driven feed pump. An excess pressure governor is a special type of control device that is typically found on turbine-driven feed pumps used in steam power plants. These pumps are responsible for delivering high-pressure feed water to the boiler, and the excess pressure governor helps regulate the pump's output to prevent overpressurization of the system. The other options are incorrect because an excess pressure governor would not be found on a main circulator pump (A), a forced draft fan (B), or a low-pressure propulsion turbine (C), as these components do not have the same high-pressure feed water requirements as a turbine-driven feed pump.
