Question 109Steam Plants - QMED

The correct answer is B) combined low pressure feed heater. The illustration SG-0025 shows a component that is used as a combined low pressure feed heater in a steam propulsion system. This type of heater is used to increase the temperature of the feed water before it enters the boiler, improving the overall efficiency of the system. The other options are incorrect because: A) a flash evaporator salt water feed heater is used to produce fresh water from seawater, C) a Butterworth feed heater is a specific type of low pressure feed heater, and D) a high pressure feed heater operates at a higher pressure than the combined low pressure feed heater shown in the illustration.
