What does a boiler feedwater regulator automatically control?

1. Pressure in the boiler

2. Temperature of the water

3. Water supply to the boiler

4. Fuel supply to the boiler

The correct answer is: Water supply to the boiler

A boiler feedwater regulator is designed specifically to manage the water supply to the boiler. Its primary function is to ensure that the boiler maintains an adequate level of water for efficient operation. By automatically controlling the flow of feedwater based on the needs of the boiler, it helps maintain the appropriate water level and prevents issues such as low water conditions, which could lead to overheating or damage to the boiler. Understanding how this regulator operates is essential because it directly impacts the safety and efficiency of the boiler system. While pressure and temperature are critical parameters in boiler operations, these are generally controlled by separate mechanisms, such as pressure regulators and temperature control systems. Furthermore, the fuel supply to the boiler is not managed by the feedwater regulator; it is typically the responsibility of fuel delivery systems that ensure the correct amount of fuel for combustion in the boiler. Therefore, the function of the boiler feedwater regulator is distinctly focused on regulating the water supply, making it the correct answer.
