Question 163Steam Plants - QMED

The correct answer is A) drain excess feed water to the distilled water tank. The DC heater automatic level dump valve is used to maintain the proper condensate level in the DC heater by automatically draining any excess feed water to the distilled water tank. This helps ensure the DC heater operates at the correct water level and prevents water from backing up into the condenser. The other options are incorrect because: B) diverts condensate from the first stage heater, C) recirculates condensate, and D) maintains the condenser hotwell level, which are not the primary functions of the DC heater automatic level dump valve.
