What should be done if there is low water in the boiler?

In the scenario of low water levels in a boiler, securing the fuel is critical to ensuring safety and preventing potential damage or catastrophic failure. When the water level is below the safe operating level, the boiler can overheat, leading to risks such as tube failure or even explosions. By securing the fuel, the combustion process is halted, which reduces the risk of damage due to high temperatures in the absence of sufficient water to absorb heat.

Addressing low water levels promptly is crucial, as it allows time for safe resolution. Once the fuel is secured, operators can assess the situation, investigate the cause of low water, and take corrective actions such as adding water to the boiler system or checking the feedwater system for issues.

Other actions, like increasing feedwater flow or increasing pressure, may not be safe or effective without first securing the operations of the boiler. Continuing operation under low water conditions can lead to severe consequences, making it imperative to prioritize safety by securing the fuel supply.
