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

The function of a level control system in a feedwater system is primarily to maintain proper water levels in the boiler or tank. This is essential because maintaining the correct water level is crucial for the safe and efficient operation of the boiler and the overall feedwater system. If the water level is too low, it can lead to overheating and damage to the boiler, while too high a water level can cause water carryover into the steam system, leading to operational issues and potential damage to equipment.

The level control system uses various sensors and control mechanisms to continuously monitor and adjust the water level, ensuring that it remains within the desired range. This involves opening or closing feedwater valves or activating pumps to add or remove water as necessary, thus safeguarding against operational risks and optimizing performance.
