Plant Operation Practice Test

Which condition should a burner always start up in?

1. High fire

2. Blank fire

3. Low fire

4. Medium fire

The correct answer is: Blank fire

Starting a burner in a blank fire condition is essential because this mode ensures safe ignition and initial operation. In blank fire, the burner operates without the introduction of fuel, allowing the system to check for proper air flow and ensure that there are no blockages or other issues present before any fuel is ignited. This approach minimizes the risk of explosions or other dangerous conditions resulting from unburned fuel igniting unexpectedly. Additionally, beginning a startup sequence in a non-fuel condition allows operators to confirm that all components of the burner and accompanying systems are functioning correctly, leading to a more controlled and reliable ignition process. Safety protocols in plant operations prioritize such precautions, making blank fire the standard for initiating burner operations effectively.
