Don Low Fire Flame Ring Rayburn Supreme Conv D20080

Don Low Fire Flame Ring Rayburn Supreme Conv D20080

The Don Low Fire Flame Ring (Part Number: D20080) is a specialist component used in vaporizing oil burner conversions for the Rayburn Supreme and Rayburn Nouvelle models. This ring is a key part of the "Don" burner assembly, specifically designed to stabilize the flame during the "low fire" or idling stage.

In a vaporizing burner, the flame ring sits atop the burner sleeves. It helps concentrate the heat on the base of the burner to maintain vaporization while ensuring the flame remains blue and clean when the oil control valve is turned down to its minimum setting.

Key Features and Specifications

Part Number: D20080.

Application: Rayburn Supreme / Nouvelle Oil Conversions.

Burner Type: Vaporizing (Sleeve) Oil Burner.

Material: High-grade heat-resistant steel or cast alloy designed to withstand constant glowing temperatures without rapid oxidation.

Function: Controls the air-to-gas mixing at the top of the burner sleeves to maintain a stable, clean flame at low temperatures.

Common Applications

Vaporizing Conversions: Specifically for Supreme and Nouvelle models that have been converted from solid fuel to oil using the Don conversion kit.

Maintenance: Replaces warped or burnt-out rings that cause the burner to "smoke" or "carbon up" when running on the low setting.

Efficiency Tuning: Essential for ensuring the cooker stays at a consistent "background" temperature without the flame extinguishing or becoming yellow and sooty.

Signs Your Flame Ring Needs Replacing

Warping: If the ring is no longer perfectly circular or flat, it will create uneven air gaps, leading to a ragged, yellow flame.

Thinning Metal: If the edges of the ring are "flaking" or appearing very thin, it will soon fail and potentially drop into the burner sleeves.

Carbon Buildup: Persistent carbon deposits on the ring often indicate it is no longer reaching the correct temperature to stay clean, usually due to material degradation.

Installation and Service Tips

Orientation: Ensure the ring is seated correctly on the inner and outer sleeves. An incorrectly seated ring is the most common cause of "smelling" or sooting in vaporizing cookers.

Carbon Removal: During your 6-monthly or annual service, carefully remove the ring and scrape away any hard carbon from the seating area to ensure a flush fit.

Handling: These parts become very brittle after they have been "fired." Handle old rings with extreme care if you intend to reuse them.

Essential Companion Products

Burner Sleeves: Inner and Outer perforated stainless steel sleeves.

Don Wicks: Replacement kindler wicks for the burner base.

Oil Control: Toby or BM Oil Control Valves (which regulate the High/Low fire).

Top Plates: Don burner top covers and heat deflectors.
