Riello Diesel Burner Spare Parts Oil Pump/Burner Nozzle/Ignition Electrodes/Ignition Transformer/Photocell (Flame Sensor)/Control Box/Solenoid Valves/Fan Motor

Riello Diesel Burner Spare Parts List

1. Oil Pump
   • Function: Draws fuel oil from the storage tank and delivers it under pressure to the burner nozzle. Ensures consistent fuel supply and atomization.
2. Burner Nozzle
   • Function: Atomizes the diesel fuel into a fine spray, ensuring proper mixing with air for complete combustion. Different nozzle sizes determine fuel flow rates.
3. Ignition Electrodes
   • Function: Generate a high-voltage spark to ignite the fuel-air mixture during burner start-up.
4. Ignition Transformer
   • Function: Steps up the voltage (220V → several kV) required for the ignition electrodes to create a spark.
5. Photocell (Flame Sensor)
   • Function: Detects the presence of flame in the combustion chamber. Provides feedback to the control box for safe operation.
6. Control Box (Burner Control Unit)
   • Function: Central electronic unit that manages the burner sequence (pre-purge, ignition, flame monitoring, shutdown). Ensures safe and automatic operation.
7. Solenoid Valves
   • Function: Control the opening and closing of the fuel supply line. Ensure precise fuel delivery and provide safety shut-off in case of malfunction.
8. Air Damper / Air Shutter
   • Function: Regulates the air intake to achieve the correct fuel-to-air ratio. Ensures efficient combustion and reduced emissions.
9. Fan Motor
   • Function: Drives the combustion air fan, supplying air into the burner head for mixing with fuel.
10. Combustion Head (with Blast Tube)
    • Function: Directs and stabilizes the fuel-air mixture into the combustion chamber. Includes flame disc, diffuser, and ensures proper flame shape.
11. Gasket Set (Seals & O-rings)
    • Function: Prevent leakage of oil, air, and flue gases within the burner assembly.
12. Oil Filter
    • Function: Removes impurities and particulates from diesel fuel before reaching the pump, preventing clogging and nozzle wear.
13. Pressure Gauge (Fuel Pump Gauge Port)
    • Function: Allows measurement of oil pump outlet pressure for calibration and troubleshooting.
14. Flexible Oil Hoses
    • Function: Connect fuel tank to burner pump. Provide safe and vibration-resistant fuel supply.
15. Motor Capacitor
    • Function: Assists the fan motor in starting and running smoothly.
16. Overheat Thermostat (Safety Thermostat)
    • Function: Shuts down burner in case of excessive temperature, protecting equipment.
17. Electrode Insulators
    • Function: Insulate ignition electrodes from burner body, ensuring proper spark.
18. Burner Housing & Mounting Flange
    • Function: Provides mechanical support, sealing, and connection between burner and combustion chamber.
