Burner nozzles for well test burner systems

A method comprising:

• conveying air and a well product to a first burner nozzle of a plurality of burner nozzles, wherein each burner nozzle of the plurality of burner nozzles comprises an outer housing that defines an internal cavity, a nozzle that is receivable within the internal cavity and that defines an atomizing chamber, and one or more apertures defined in the nozzle;
• conveying a portion of the air, via an air transfer conduit, and a portion of the well product, via a well product transfer conduit, from the first burner nozzle to a second burner nozzle of the plurality of burner nozzles, wherein the air transfer conduit and the well product transfer conduit interpose and fluidly couple the outer housing of the first burner nozzle with the outer housing of the second burner nozzle;
• moving the first burner nozzle to a closed configuration which blocks a flow of the well product into the atomizing chamber of the first burner nozzle;
• and
• flowing air through the first burner nozzle to cool the first burner nozzle.

A burner nozzle assembly, comprising:

• a plurality of burner nozzles;
• an air transfer conduit interposing and fluidly coupling an outer housing of a first burner nozzle of the plurality of burner nozzles with a second burner nozzle of the plurality of burner nozzles, wherein air flows from the first burner nozzle to the second burner nozzle through the air transfer conduit;
• and
• a well product transfer conduit interposing and fluidly coupling the outer housing of the first burner nozzle with the second burner nozzle, wherein well product flows from the first burner nozzle to the second burner nozzle through the well product transfer conduit.
