What is the main function of a level control system in a feedwater system?

A level control system in a feedwater system primarily serves to maintain the appropriate water levels within various components, such as the boiler or feedwater tank. This is crucial for efficient operation and safety in steam generation processes. Maintaining optimal water levels helps prevent situations that could lead to boiler damage, such as low water levels, which can result in overheating and structural failures, or high water levels that may cause carryover of water into the steam system.

The importance of maintaining water levels can't be overstated, as it directly impacts the efficiency and reliability of the entire system. By ensuring that the water levels are maintained within predetermined limits, the level control system contributes to overall system stability and performance.
