Question 444Steam Plants - Assistant Engineer70% to pass
A boiler accumulation test is used to measure the _______________.
AI Explanation
The correct answer is A) total relieving capacity of the boiler safety valves.
The boiler accumulation test is used to measure the total relieving capacity of the boiler safety valves. This is done by shutting off the steam supply to the boiler and allowing the pressure to rise until the safety valves lift. The maximum pressure reached during this test, known as the "accumulation pressure," is then used to calculate the total relieving capacity of the safety valves.
The other options are incorrect because they do not accurately describe the purpose of the boiler accumulation test. Option B measures the steam generating capacity, option C measures the blow down pressure, and option D measures the lifting pressure of the safety valves, which is a different parameter than the total relieving capacity.
