Question 89Steam Plants - Assistant Engineer70% to pass
When preparing to cut a boiler in on the line, you determine that the steam pressure of the incoming boiler is about 5 psig above line pressure. Which of the following steps should you take next?
AI Explanation
The correct answer is A) Open the desuperheated steam stop.
When the incoming boiler steam pressure is slightly higher than the line pressure, the proper next step is to open the desuperheated steam stop. This allows the higher pressure steam to slowly equalize with the lower line pressure, preventing a sudden rush of steam that could damage equipment. The other options are incorrect, as they do not directly address the need to safely equalize the pressure difference before cutting the boiler in on the line.
