Study Notes
Preparing to Start a Steam Boiler
- Ensure the boiler has a valid inspection certificate, and it has been properly checked, cleaned, filled with water, closed, and tightened, with all auxiliary systems prepared.
- Review the manufacturer's recommendations for startup to ensure compliance with specific guidelines.
Preparing Piping and Fuel Systems
- If warming up the piping system with the boiler, open suction and discharge valves on vacuum or condensate pumps, and set pump switches to "auto" or "on".
- Open the water supply to the feeder valve, if equipped, and ensure the deaerator and feedwater make-up system are filled to operating levels.
- Ensure fuel availability to stop valves in pilot and main burner supply lines, and open the return line stop valve if using fuel oil.
- Verify that fuel lines, filter, and fuel pump are operating as expected, with all parameters within expected range.
Final Checks
- Ensure unobstructed fresh air supply to the boiler room.
- Check pressure settings of operating and high limit controls.
- Verify the boiler control switch on the panel is in the "off" position.
- Set the control switch to "low" on boilers with high-low firing rate control, and to "manual" and low-fire position on boilers with fully modulating firing rate control.
- If equipped with a mechanical reset, push the reset button on the low water fuel cut-off and/or high limit control.
