Why is maintaining proper water levels in a boiler crucial?

Maintaining proper water levels in a boiler is crucial primarily to prevent overheating and potential failures. The water level is essential for the safe operation of the boiler because it acts as a coolant and absorbs the heat generated by burning fuel. If the water level falls too low, there is a risk that the boiler tubes may become exposed to the heat without adequate cooling. This can lead to overheating of the tubes, which can cause warping, cracking, or even catastrophic failures such as tube bursts.

Additionally, in the event of low water levels, steam production becomes inconsistent, which can impact the efficiency and functionality of the overall system. Regular monitoring and control of water levels help ensure safe operation, prevent damage, and maintain efficiency in operation.
