What is the primary function of a feedwater control valve?

The primary function of a feedwater control valve is to regulate the flow of feedwater entering the boiler based on the steam generation requirements. This is crucial in maintaining optimal performance and efficiency of the boiler system. As steam is generated in the boiler, the amount of feedwater needs to be adjusted to match the steam output. The control valve ensures that there is a continuous and appropriate supply of feedwater to meet the operational demand of the boiler, thereby preventing issues such as boiler starvation or flooding.

This regulation involves monitoring the pressure and temperature in the boiler and making real-time adjustments to ensure the system operates smoothly. By modulating flow, the feedwater control valve plays a vital role in maintaining the balance between steam production and feedwater supply, which is essential for safe and efficient boiler operation.
