Question 272Steam Plants - 1st Asst/Chief

The correct answer is D) completely drain the superheater. After restoring the normal water level in a boiler following a high water casualty, the proper procedure is to completely drain the superheater. This is done to remove any water that may have accumulated in the superheater, which could potentially damage the superheater tubes if the boiler is put back on line without this precaution. The other answer choices are incorrect because: A) Immediately putting the boiler back on line without draining the superheater could lead to damage; B) Draining the economizer is not the appropriate step in this scenario; and C) Blowing down the water gage glass does not address the issue of water in the superheater.
