How to debug and follow the steps for boiler burners?
After completing the boiler renovation, a crucial step is required for the burner to function properly, which is debugging. Now, let’s learn together how to debug the boiler burner and its steps?
1. Test the control circuit for short circuits using a multimeter without power on;
2. Power on, manually start the fan and disconnect it to determine if the fan is running forward;
3. Start the burner and observe if the air damper operates normally;
4. If ignition is unsuccessful, check the fuel source circuit, such as fuel pressure, whether the fuel solenoid valve is open, etc;
5. After successful ignition, observe the chimney to see if there is any black smoke, and adjust the air or fuel distribution appropriately;
6. Switch to high load, observe for black smoke, and adjust the air or fuel distribution;
7. After stopping the engine, ignite it multiple times, turn it on, and observe if there is any stalling phenomenon;
The debugging of a burner is not something that can be clearly explained in just one or two sentences. The steps are roughly as above, but the process of troubleshooting is ever-changing and can only be achieved through accumulating experience in daily work.
