Abstract
A burner nozzle includes an outer housing, and a nozzle and a piston receivable within the outer housing. The piston is movable between an open position, where air and a well product are able to enter an atomizing chamber to generate an air/well product mixture, and a closed position, where the piston moves to stop a flow of the well product and a metered amount of air flows through one or more leak paths defined between a leading edge of each axial flow port and an adjacent closure surface provided by the nozzle body and into the atomizing chamber.
Claims21
A burner nozzle, comprising:
- an outer housing that defines an internal cavity;
- a nozzle receivable within the internal cavity and defining an atomizing chamber;
- and
- a piston receivable within the internal cavity and providing a piston body that defines a piston chamber that receives at least a portion of the nozzle,
- wherein the piston is axially movable within the internal cavity between an open position, where air and a well product provided to the outer housing enter the atomizing chamber to generate an air/well product mixture, and a closed position, where the piston moves to stop a flow of the well product and a metered amount of air flows through one or more leak paths and into the atomizing chamber, the one or more leak paths being defined near a leading edge of the piston.
A method, comprising:
- conveying air and a well product to a burner nozzle, the burner nozzle including an outer housing that defines an internal cavity, a nozzle receivable within the internal cavity and defining an atomizing chamber, and a piston receivable within the internal cavity and providing a piston body that defines a piston chamber that receives at least a portion of the nozzle;
- receiving the air and the well product into the atomizing chamber and thereby generating an air/well product mixture;
- moving the piston axially within the internal cavity to a closed position, where a flow of the well product into the atomizing chamber stops and one or more leak paths are defined near a leading edge of the piston;
- allowing a metered amount of air to flow through the one or more leak paths and into the atomizing chamber;
- and
- cooling the burner nozzle as the metered amount of air escapes the burner nozzle via a nozzle outlet.
A burner nozzle assembly, comprising:
- a plurality of burner nozzles, each burner nozzle including an outer housing and a nozzle received within an interior of the outer housing;
- an air inlet that conveys air into a first burner nozzle of the plurality of burner nozzles;
- a well product inlet that conveys a well product into the first burner nozzle of the plurality of burner nozzles;
- an air transfer conduit interposing and fluidly coupling the outer housing of adjacent burner nozzles such that the air is transferred from the first burner nozzle to all subsequent burner nozzles;
- and
- a well product transfer conduit interposing and fluidly coupling the outer housing of adjacent burner nozzles such that the well product is transferred from the first burner nozzle to all subsequent burner nozzles.
