What kind of oil can be used in a waste oil burner

1. Waste Mineral Oils

• Used engine oil: Lubricating oil from vehicles or machinery (requires filtration to remove impurities).

• Used hydraulic oil: Waste oil from industrial equipment or construction machinery.

• Used gearbox/transmission oil: Discarded oil from vehicles or heavy machinery.

• Cutting oil/metalworking fluids: Waste oil from machining processes (requires pretreatment).

2. Waste Vegetable/Bio-Oils

• Used cooking oil: Frying oils (e.g., waste grease, palm oil, rapeseed oil).

• Expired vegetable oil: Spoiled or inedible oils (e.g., soybean oil, corn oil).

• Biodiesel byproducts: Residual waste oils from biodiesel production.

3. Mixed Waste Oils

• Blends of different waste oils (must ensure compatibility to avoid clogs or chemical reactions).

4. Other Waste Oils(A heavy oil burner would be better)

• Tar/asphalt oils: Byproducts from certain industrial processes (requires high-temperature burners).

• Oil sludge: Residues from fuel tanks or crude oil storage (requires specialized equipment).

• Marine waste oils: Residual fuel oils from ship engines (e.g., heavy fuel residues).

Important Considerations

1. Pretreatment Requirements:

   • Waste oil must be filtered, settled, or centrifuged to remove water, metal particles, and other impurities to prevent nozzle clogging.

   • High-viscosity oils (e.g., heavy oil, sludge) may need heating for proper flow.

2. Equipment Compatibility:

   • Different burners are designed for specific oil types (e.g., a used engine oil burner may not work well with vegetable oil).

   • Some waste oils (e.g., high chlorine/sulfur content) may corrode equipment or require exhaust treatment (e.g., SCR, scrubbers).

3. Environmental Regulations:

   • Burning waste oil can produce harmful emissions (dioxins, SO₂, etc.) and must comply with local environmental laws.

   • Some countries prohibit burning untreated hazardous waste oils (e.g., PCB-contaminated oils).

Oils Not Recommended

• Gasoline or light oils: Highly flammable, posing explosion risks.

• Oils with solvents/chemicals: May release toxic fumes.

• High-salt/acidic waste oils: Can accelerate equipment corrosion.

Always check the burner manufacturer’s specifications and ensure compliance with environmental regulations before use.
