Question 7Steam Plants - 1st Asst/Chief

The correct answer is A) superheater. Excessive foaming in a steaming boiler can cause damage to the superheater. The superheater is a critical component of the boiler system that increases the temperature of the steam beyond the saturation point. Excessive foaming can lead to carry-over of water droplets into the superheater, potentially causing thermal and mechanical stresses that can damage the superheater tubes. The other options are incorrect because: B) the internal feed pipe is not directly affected by excessive foaming, C) the desuperheater is designed to reduce steam temperature and would not be damaged by foaming, and D) the economizer is located in the boiler's feedwater system and is not impacted by foaming in the steam space.
