Study Notes
Importance of Fundamental Equipment Knowledge
- Having fundamental equipment knowledge is crucial before operating a boiler to ensure safe and efficient operation.
- Operators are assumed to be thoroughly familiar with firing equipment and controls to prevent accidents and optimize performance.
Routine Boiler Operation Checks
- Following a routine while checking boiler operation helps identify potential issues before they become major problems.
- A routine check ensures that the boiler is operating within safe and efficient parameters.
Control System Knowledge and Troubleshooting
- Good knowledge of the control system is essential for effective troubleshooting to minimize downtime and reduce costs.
- Understanding the control system helps operators quickly identify and rectify issues, preventing costly delays.
Preventing Downtime and Correcting Boiler Trouble
- Regular maintenance and routine checks can help prevent costly downtime or delays in boiler operation.
- Methods of correcting boiler trouble can usually be found in the boiler's manual or troubleshooting guides.
Installation and Adjustment Assumptions
- It is assumed that the boiler has been properly installed and adjusted according to the manufacturer's instructions.
Troubleshooting Common Boiler Issues
- If the blower starts but stops again after 5-10 seconds, the electrical supply or blower motor should be checked.
- If there is no ignition despite the presence of spark, the fuel supply or ignition system should be checked.
- If the boiler pressure or temperature is above the cut-in setting of the operating control, the pressure or temperature sensors should be checked.
- If the burner stays on low-fire, the fuel supply or burner components should be checked.
- If a shutdown occurs during firing, the flame failure devices or safety controls should be checked.
- If the air dampers are not functioning, the damper motors or linkages should be checked.
- If there is no main flame despite having an insufficient pilot or low-fire flame, the fuel supply or ignition system should be checked.
- If the draft fan does not start, the electrical supply or fan motor should be checked.
