What operational problem can occur from panting in a boiler?

Panting in a boiler refers to the movement or vibration of the boiler components due to fluctuations in pressure and water level, resulting from rapid changes in steam demand or other operational conditions. This can lead to excessive noise and vibration, manifesting as thumping or pounding sounds during operation.

The presence of excessive noise and vibration is a clear indication of mechanical strain on the components, which could potentially lead to equipment failure or misalignment over time if not addressed.

While other options mention issues like reduced steam pressure, overheating, or water hammer, they focus on different operational problems. For example, reduced steam pressure could stem from other factors such as inadequate fuel supply or poor heat exchange. Overheating might arise from other operational anomalies such as insufficient cooling or high combustion heat. Water hammer, while a significant concern, relates specifically to the sudden movement of condensate rather than the vibrations associated with panting. These aspects highlight that while they are serious boiler concerns, they differ from the direct implications of panting.
