What is the purpose of an accumulation test in boiler operations?

The purpose of an accumulation test in boiler operations is to assess the functioning and safety of the safety valves. During this test, steam is generated in the boiler until the safety valve lifts, which indicates that the boiler pressure has reached the design limit. This is crucial for ensuring that the safety valve effectively protects the boiler from overpressure conditions, which could lead to dangerous situations.

The accumulation test provides valuable data on the responsiveness of the safety valve and verifies that it operates correctly under high pressure. By accumulating steam until the safety relief valve opens, operators can confirm not only the lift pressure but also the seat tightness and the valve's capacity to handle the required steam flow.

This test is vital for safe boiler operation and regulatory compliance, as it helps maintain the integrity of the pressure system and prevents accidents related to boiler overpressure. Other options provided do not pertain correctly to the specific function of the accumulation test, as it is not designed for measuring water hardness, checking for leaks, or assessing fuel efficiency.
