What is checked during an accumulation test?

During an accumulation test, the primary focus is on measuring the boiler pressure over time. This test evaluates how a boiler responds to a sudden release of pressure, which can occur during conditions where the boiler is forced to operate without the usual load conditions, such as during a malfunction or an emergency shutdown.

In particular, the test helps determine whether the safety relief valves are functioning correctly and if the boiler is capable of effectively managing pressure increases without exceeding safety limits. The results yield critical data on how quickly the system can release pressure and stabilize, ensuring that the boiler remains safe and operational under transient conditions.

Other aspects like temperature response, energy efficiency, and fuel consumption rates are not the central focus of an accumulation test; rather, they pertain to different operational evaluations of the boiler system. Thus, confirming the pressure response during this test is vital for maintaining the operational integrity and safety of high-pressure boilers.
