Question 107Steam Plants - Assistant Engineer
70% to passAn obstruction in the top connection of a boiler gage glass will cause the _______________.
Agage glass to overheat and break
Bgage glass to be blown empty
Cwater level to rise slowly in the glass
Dwater level to remain constant in the glass
AI Explanation
The correct answer is C) the water level to rise slowly in the glass. An obstruction in the top connection of a boiler gage glass will restrict the flow of steam into the glass, causing the water level in the glass to rise slowly. This is because the water level in the boiler is still rising, but the steam cannot escape from the top of the gage glass, resulting in the water level increasing in the glass. The other options are incorrect because: A) the gage glass would not overheat and break due to the obstruction, B) the gage glass would not be blown empty, and D) the water level would not remain constant, as it would rise slowly due to the restricted steam flow.
