How do you prevent a boiler from overheating?

To prevent a boiler from overheating, utilizing safety controls, regular monitoring, and maintaining appropriate water levels is crucial. Safety controls are designed to automatically regulate the operating conditions of the boiler, minimizing risks associated with excessive temperatures. By integrating various sensors and automated systems, these controls can shut down the boiler or reduce fuel supply in response to abnormal conditions.

Regular monitoring ensures that operators are continuously aware of key indicators such as temperature, pressure, and water levels. This vigilance allows for immediate corrective actions to be taken if any readings deviate from the optimal range, thereby preventing overheating. Maintaining appropriate water levels is essential as it directly influences the boiler's ability to absorb heat. Insufficient water levels can lead to overheating and potentially catastrophic failure.

This approach combines a proactive and systematic method to maintain safety, optimizing the boiler's performance while minimizing risks associated with overheating. Other options would not effectively address the complexity of boiler operation and safety.
