What it is

The air diffuser is a Riello burner component that sits in the combustion head and shapes the air flow as it leaves the blast tube. It controls how combustion air is distributed around the fuel spray, which directly affects flame shape and stability. This part is listed for the Riello Gulliver burner family.

Signs this part needs replacing

  • Soot deposits or blackening around the combustion head
  • Unstable or misshapen flame at the burner
  • Combustion readings that cannot be brought into range by normal adjustment
  • Visible distortion, cracking or erosion of the diffuser
  • Rumbling or pulsating noise from the burner during firing

Before you order

  • Confirm the burner model and code against the fit list above
  • Check the existing diffuser for damage before removal so the fault is correctly identified
  • Verify the part number 3007994 matches the component being replaced
  • Inspect the combustion head and electrodes while access is available
