In automatic boiler controls, what is the primary purpose of the automatic feedwater control system?

• A. To maintain a constant temperature
• B. To maintain boiler water level within a maximum deviation of +/- how many inches?
• C. To control fuel supply to the boiler
• D. To monitor air pressure

Answer: (B)

The primary purpose of the automatic feedwater control system is to maintain boiler water level within specified limits, typically allowing for a maximum deviation of just a few inches. This is crucial because maintaining an appropriate water level in the boiler is essential for safe and efficient operation. If the water level is too low, it can lead to unsafe conditions such as overheating and potential damage to the boiler. Conversely, if the water level is too high, it can cause water carryover into the steam system, resulting in operational inefficiencies and potential equipment damage. Automatic feedwater control systems continuously monitor the water level and adjust the feedwater flow to keep the level within the desired range. This stability in water level is vital not only for safety but also for optimizing boiler performance and efficiency. Therefore, the focus on water level control directly correlates with the effectiveness and reliability of boiler operations.
