What would likely happen if a boiler is operated at temperatures higher than intended?

Operating a boiler at temperatures higher than intended can pose significant safety risks, primarily due to increased pressure and thermal stress on the boiler components. High temperatures can lead to the failure of safety mechanisms designed to prevent accidents, increasing the likelihood of catastrophic events such as explosions. The structural integrity of the boiler itself can be compromised, leading to potential ruptures or leaks of steam and hot water.

In addition to safety concerns, excessive temperatures can cause rapid wear and tear on materials, which can result in further operational hazards. Therefore, it's crucial for operators to adhere strictly to the recommended temperature guidelines to ensure safe and efficient operation.
