What are the consequences of operating a boiler with excessive pressure?

Operating a boiler with excessive pressure can lead to significant risks, primarily the increased likelihood of mechanical failure and potentially catastrophic events such as a boiler explosion.

When a boiler is subjected to pressures beyond its designed capacity, it can cause stress on the materials and components, leading to fatigue, wear, or even rupture. Over time, this excessive pressure compromises the integrity of the boiler structure, increasing the chances of leaks or failure of safety devices.

In addition, excessive pressure may activate safety relief devices more frequently, requiring them to function under more strenuous conditions, which can lead to their premature wear and subsequent failure. Furthermore, if safety protocols are not properly followed, the situation could escalate into an explosion, endangering the lives of workers and causing significant property damage.

The other choices imply beneficial outcomes such as increased efficiency or reduced costs, which do not accurately reflect the dangers associated with operating at excessive pressure. Instead, safe operation within the designated pressure limits is crucial for the longevity and safe functioning of boiler systems.
