A fuel regulating governor is controlled by which factor?

1. Water temperature

2. Fuel pressure

3. Steam pressure

4. Electric current

The correct answer is: Steam pressure

The fuel regulating governor is primarily controlled by steam pressure. In boiler systems, maintaining the correct steam pressure is crucial for efficient operation; therefore, the governor adjusts the fuel supply based on the steam pressure readings. When steam pressure decreases, the governor will increase the fuel supply to boost the steam generation, and if the steam pressure is too high, it will reduce the fuel to prevent overpressure conditions. This ensures that the boiler operates within safe and efficient parameters, which is essential for both performance and safety. While other factors like water temperature, fuel pressure, and electric current can influence overall boiler operation, they do not directly control the fuel regulating governor in the same way steam pressure does. Understanding this relationship is key for effective boiler management and maintaining system stability.
