What is a common practice to prevent boiler overheating?

Ensuring sufficient water levels is essential in preventing boiler overheating, as water acts as a crucial coolant within the system. A boiler operates safely and efficiently when it is adequately filled with water, which absorbs the heat generated during combustion. If the water level drops too low, the heat can cause the boiler components to exceed their safe operating temperatures, potentially leading to damage or catastrophic failure.

Maintaining the correct water level involves regular monitoring and controlling the feedwater supply to compensate for steam loss and other factors that might decrease water levels. By ensuring that water is consistently at the appropriate level, operators can significantly reduce the risk of overheating and promote the safe operation of the boiler.
