After restoring the normal water level in a boiler following a high water casualty, you should _______________.
AI Explanation
The correct answer is C) completely drain the superheater.
After restoring the normal water level in a boiler following a high water casualty, the superheater should be completely drained. This is because the high water level could have flooded the superheater, which could damage the superheater tubes if the boiler is immediately put back on line. Completely draining the superheater allows any accumulated water to be removed before the boiler is returned to normal operation.
The other options are incorrect because: A) draining the economizer is not necessary, B) immediately putting the boiler back on line could damage the superheater, and D) blowing down the water gage glass does not address the potential issue with the superheater.
