Boiler water carryover to the steam turbines is the greatest concern for the engineering plant when which type of boiler casualty occurs?

Boiler water carryover to the steam turbines is primarily a concern during a high water condition in the boiler. When there is high water, the water level rises too close to the steam outlet, which can lead to the entrainment of water droplets in the steam. This contamination can cause significant damage to the turbines, including erosion and corrosion, as well as loss of efficiency in steam generation.

High water levels can prevent proper water-steam separation, allowing impurities present in the water, such as dissolved solids, to reach the turbines. This situation may lead to mechanical failure or operational difficulties, making it critical for operators to monitor and control the water level within the boiler to avoid such consequences.
