A liquid atomizing spray nozzle for admixing a liquid hydrocarbon fuel with oxygen (air) and burning the mixture to supply heat. The burner body portion of the device is constituted of a pair of concentric tubes, each provided with an inlet and annular outlet for the fuel and oxygen, respectively. A deflector of conic shape is axially mounted within the inside tube, the sloped side of which is faced inwardly toward the annular outlets and in a straight line therewith so that both of the concentric tubular columns forming the streams emitted from the annular outlets of the concentric tubes impact on the sloped surface near the apex of the cone to admix one stream with the other, and are forced outwardly to form a combustible mixture which, on ignition, burns ex situ of the burner body. The deflector is extended outwardly from the burner body at a critical distance ranging from about 0.5 to about 5 times the diameter of the annular outlet through which the oxygen is ejected.
