Industrial Oil Burners

An industrial oil burner is a burner unit that atomizes fuel oil and mixes it with air for combustion. It is used to heat large vessels or furnaces by burning fuel oil (such as diesel or heavy fuel oil) under controlled conditions to generate heat.

Type of Industrial Oil Burners

Burner Design: Typically, high-pressure spray burners where fuel is pumped through a nozzle to create a fine mist. Some use rotary cup atomizers. Burners can be single-stage or modulating (adjust flame intensity).

Fuel Types: Designed for various oils – from light distillate oil (diesel, kerosene) to heavy bunker fuel (used in large boilers with pre-heaters).

Ignition/Controls: Equipped with ignition systems (spark or pilot flame), flame detectors (UV or ionization), and automatic safety controls. Many have adjustable air dampers and flame observation ports.

Materials: The nozzle and pump components are stainless or bronze to resist corrosion. Burner housings and mounting plates are steel. Internal components (mixing chambers, flame tubes) are heat-resistant alloys.

Applications in Various Industries

Oil burners are used wherever large-scale heat is needed and gas is unavailable or for high temperatures. Common in boiler systems for steam generation (in power plants, chemical plants), furnaces for heat treating metals, paint drying ovens, dryers in textile or wood industries, and industrial laundries. They serve petrochemical refineries, food processing (baking ovens), and municipal waste incinerators. Essentially any process requiring controlled high heat (up to 1000°C) can use an oil burner with the appropriate furnace or boiler.

Material Selection Considerations

Combustion chambers and exposed parts must withstand high temperatures and corrosive combustion products. Burner nozzles and pumps use stainless steel or bronze for corrosion resistance to oil. O-rings and seals are made of fluorocarbon (Viton) to resist oil and heat. Flame tubes and mixing elbows often use cast iron or high-temperature steel (with chrome/aluminium alloys) to prevent distortion. The fuel system (pipes, valves) uses steel rated for oil and pressure. Motors and electrical components must be rated for the environment (often NEMA-rated enclosures). All materials must prevent oil leakage and be able to handle the fire and pressure generated.
