Which parameter is most crucial to monitor continuously in a feedwater system?

Monitoring feedwater pressure continuously in a feedwater system is crucial because it directly impacts the performance and efficiency of the entire system. Feedwater pressure ensures that the water is being delivered at the correct rate to the boiler or steam generator. If the pressure is too low, it can lead to insufficient water flow, potentially causing heating issues or even damaging the equipment due to overheating or dry conditions. Conversely, excessive pressure can cause leaks, ruptures, or other mechanical failures, impacting system safety and operation.

Stable feedwater pressure also helps in maintaining the desired steam quality and ensuring that the water treatment processes are effective, as variations in pressure can affect the chemical dosing and the overall quality of the water processed within the system. Continuous monitoring allows for timely adjustments and maintenance actions, which are critical in preventing operational disruptions and ensuring the reliability and longevity of the feedwater system.
