The primary purpose of the water level in a boiler is to ensure proper steam generation. Maintaining the correct water level is critical because it directly impacts the efficiency and safety of the steam generation process. If the water level is too low, it can lead to overheating and potentially damaging the boiler components, such as the tubes and the pressure vessel itself, which must remain submerged to operate safely and effectively. Conversely, if the water level is too high, it can result in water carryover into the steam system, which can cause water hammer, damage to equipment, and possible operation failures.

Beyond this, the water level also plays a role in regulating the heat exchange process within the boiler. Properly maintaining the water level enables the boiler to effectively absorb heat from the combustion gases and convert it into steam, which is essential for the overall operation of systems that rely on steam for power, heating, or other applications.
