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

When the water level in a boiler drops too low, the boiler can overheat and potentially explode. This situation occurs because the water serves as a coolant and a medium for generating steam. If the water level falls below the safe operating range, the metal components of the boiler can become exposed to direct heat from the burner. This exposure can lead to overheating of the boiler's materials, which can weaken structural integrity and cause catastrophic failures, including explosions, due to the rapid buildup of pressure and damage to the boiler's components.

Maintaining the proper water level is critical for safe boiler operations. It ensures that the heat generated is absorbed and converted into steam while preventing damage to the boiler from overheating. Monitoring and maintaining water levels are essential practices in boiler management to ensure safe and efficient operation.
