Question 76Steam Plants - QMED

The correct answer is C. The steam drum's water level control system is the last line of defense in preventing moisture carryover into the saturated steam leaving the steam drum. The water level control system, represented by item C in the illustration, is responsible for maintaining the proper water level in the steam drum, which is crucial in preventing water droplets from being carried over into the steam supply. The other options are incorrect because they do not directly relate to controlling the water level in the steam drum. Option A (M) represents the drum's steam outlet, while options B (B) and D (N) are associated with the steam/water separation mechanisms, but do not directly control the water level.
