Question 108Steam Plants - QMED

The correct answer is B) first stage heater. The upper section of the feed water heater indicated by "G" in the illustration SG-0025 is used as the first stage heater. This is because the feed water heater is typically a multi-stage device that uses the waste heat from various parts of the steam system to preheat the feed water before it enters the boiler. The first stage heater is the initial step in this preheating process, raising the temperature of the feed water before it undergoes further heating in subsequent stages. The other options are incorrect because they do not accurately describe the function of the component indicated by "G" in the illustration. The feed water heater is not an after condenser, a gland exhaust condenser, or a drain cooler.
