Question 433Steam Plants - Assistant Engineer

The correct answer is B) reduce the feed water flow to the boiler. When the water level in a steaming boiler rises to within 2 inches of the top of the gage glass, it indicates that the feed water flow to the boiler is excessive. Reducing the feed water flow will help to lower the water level back to the proper operating range. This immediate action prevents the water level from continuing to rise, which could lead to damage to the boiler or even a dangerous situation. The other options are incorrect because they do not address the immediate need to reduce the feed water flow. Securing the fires and opening the bottom blow valve (A) or opening the surface blow line (C) would not directly address the rising water level. Securing the feed water flow (D) is correct, but reducing the flow is a more immediate action to take.
