Pre-Event: Design and Installation Considerations
- Keep fuel train valves, piping and components as high off the ground as possible.
- Make sure that burner-management systems are not obsolete.
- Consider NEMA weatherproof control cabinets, even inside.
- Keep spare components on site but in protected areas.
- Prepare a list of vendors and suppliers for mission-critical components.
- Run vent lines outside of the building from all regulators and switches.
- Install rental boiler connections.
- Install dual fuel systems and or at least connections for backup.
- Consider the availability of components used in the fuel train and control systems.
- Have all documentation in order, including control and electrical drawings, lists of components, and setpoints for controls.
Post-Event: Dry Out, Inspection, Testing and Recommissioning Issues
- Check all vent lines and regulators for water incursion.
- Dry out all refractory -- is a critical step.
- Pay special attention to control panels and critical components.
- Drain water from fuel oil tanks and clean.
- Test all safety interlocks.
- Check all valves for leakage.
- Remove all burners check for corrosion.
- Reset and check fuel air ratios.
- Check and clean combustion air fans.
- Have procedures in place for emergency response when an event may be imminent.
