Question 6Steam Plants - 1st Asst/Chief

The correct answer is C) damage to the superheater tubes. High boiler water level can cause carryover, which is the entrainment of water droplets in the steam. This can lead to damage to the superheater tubes, as the water droplets can erode or overheat the superheater surfaces. The superheater is responsible for further heating the steam to a high temperature, and the presence of water droplets can disrupt this process and cause damage. The other answer choices are incorrect because warped screen tubes, warped waterwall tubes, and damage to the economizer are not directly caused by high boiler water level and carryover. These components are not as susceptible to the effects of carryover as the superheater tubes.
