Question 194Motor Plants - 1st Asst/Chief

The correct answer is C) main condensate pump. The main condensate pump is responsible for circulating the condensed steam from the main condenser back to the boiler. This is a crucial component in the steam propulsion system, as it ensures the continuous recycling of the condensed steam to maintain the boiler's water level and overall efficiency. The other options are incorrect because: A) a waste heat boiler circulating pump is used to circulate the water in a waste heat boiler, B) a fuel oil service pump is used to supply fuel oil to the burners, and D) a boiler water feed pump is used to supply water to the boiler, which is a different function from the main condensate pump.
