When raising steam on an idle boiler and the steam pressure has risen to about 5 pounds more than the pressure of the boiler already on the line, you can _______________.
AI Explanation
The correct answer is A) put the boiler on the line.
When raising steam on an idle boiler, you can put the boiler on the line once the steam pressure has risen to about 5 pounds more than the pressure of the boiler already on the line. This allows the pressure to equalize and the boiler to be safely integrated into the system.
The other options are incorrect because: B) closing the superheater vent is not necessary for putting the boiler on the line, C) increasing the boiler firing rate could cause the pressure to rise too quickly, and D) closing the air cock is not the appropriate action for this situation.
