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 D) put the boiler on the line.
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, the proper procedure is to put the boiler on the line. This allows the pressure differential to be equalized, preventing a sudden surge of steam that could damage the system. The other options, such as increasing the firing rate (A) or closing the superheater vent (B) or air cock (C), are not the appropriate actions in this scenario, as they could further increase the pressure differential and lead to potentially dangerous consequences.
