What will increase along with the valve failing open due to a ruptured feedwater control valve diaphragm?

• A. Steam pressure
• B. Boiler water level
• C. Fuel oil flow
• D. Temperature in the drum

Answer: (B)

When a feedwater control valve fails in the open position, it allows an uncontrolled influx of feedwater into the boiler. As more feedwater enters the boiler, it displaces some of the steam space and increases the overall water level within the boiler drum. This condition can lead to a rise in the boiler water level because the system is not able to regulate the amount of water being pumped into the boiler effectively. The rise in water level is critical to monitor, as it can result in problems such as water carryover into the steam system or potential flooding of the boiler, which can damage the equipment or create unsafe operating conditions. While steam pressure, fuel oil flow, and temperature in the drum are important parameters to consider, they do not directly correlate with the failure of the feedwater control valve to the same extent as the boiler water level. An increase in the water level will typically influence the steam production and the capacity of the boiler to generate steam at the desired pressure and temperature, but the immediate effect of the valve failing open is a rise in the boiler water level itself.
