Peacock Liquid Burner The Peacock Burner was developed to flare liquid hydrocarbons without liquid fallout or soot formation (smoke). These burners provide excellent service for well testing operations and have been used in applications in the Gulf of Mexico and Arabian Gulf. When only oil is flared, a high pressure air or gas source is required to provide mechanical atomization which ensures the mixture is a fine mist as it exits the burner nozzle. This particular burner nozzle is designed to accept separate high pressure oil and air/gas streams for maximum efficiency.
