What is the purpose of a water-level control system in a boiler?

The purpose of a water-level control system in a boiler is essential for maintaining the proper water level. This system ensures that there is neither too much nor too little water in the boiler, which is crucial for safe and efficient operation. A properly functioning water-level control system helps prevent issues such as water carryover into the steam lines, which can lead to damage, and low water levels that can cause the boiler to run dry, potentially resulting in catastrophic failure or explosion.

Maintaining the correct water level is pivotal for the boiler's thermal efficiency and operational stability, as it directly influences steam production and pressure control. Therefore, the water-level control system is a critical component in safeguarding the boiler against operational hazards and ensuring that it functions effectively to produce the needed steam.
