What can happen if the water level in a boiler is too low?

When the water level in a boiler is too low, the boiler can overheat, leading to significant damage. This occurs because the water serves as a heat sink, absorbing the heat produced during combustion. If the water level drops below an appropriate threshold, the metal components of the boiler can become exposed to the hot gases produced from the combustion process. This can cause temperature spikes that may result in overheating of the boiler's metal structure, potentially leading to catastrophic failures such as warping, cracking, or even ruptures.

This scenario emphasizes the importance of maintaining the proper water level within the boiler to ensure safe and efficient operation. Regular monitoring and control systems are vital in preventing low-water conditions, which could threaten the integrity of the entire system.
