Question 108Steam Plants - Assistant Engineer
70% to passWhich of the following actions, if any, should be taken if the water gage glass on a steaming boiler breaks?
AReduce the firing rate.
BClose the gage glass cutout valves.
CClose in on the feed stop-check valve.
DNo action is necessary since checks in the cutout valves automatically seat to stop loss of steam and water.
AI Explanation
The correct answer is B) Close the gage glass cutout valves. If the water gage glass on a steaming boiler breaks, the proper action is to close the gage glass cutout valves. This isolates the gage glass from the boiler, preventing the loss of steam and water from the boiler. The other options are incorrect - reducing the firing rate or closing the feed stop-check valve would not address the immediate issue of the broken gage glass. Additionally, the checks in the cutout valves do not automatically seat to stop the loss of steam and water, so no action is not the correct response.
