The water hammer effect is a common operational issue that can arise from inadequate boiler monitoring. This phenomenon occurs when there is a sudden change in the velocity of water within the boiler system, often caused by rapid changes in pressure or temperature. If a boiler is not monitored properly, operators may fail to detect conditions that lead to steam pockets forming, resulting in a sudden surge of water when these pockets collapse. This can create a loud banging noise and potentially cause damage to the boiler and piping system.

Effective monitoring involves keeping track of pressure, temperature, water levels, and other critical parameters. This oversight is essential to ensure the boiler operates smoothly and efficiently, reducing the risk of problems such as water hammer. In contrast, constant optimal pressure, automated fuel feeding, and low emission levels are related to proper control and operating conditions, which would likely be maintained with vigilant monitoring rather than negatively impacted by inadequate monitoring.
