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.

In apparatus for admixing a liquid hydrocarbon fuel and oxygen, air or other oxygen-containing gas, within which is included a body constituted of coaxially mounted tubular members, a small diameter pipe, shaft and shaft guide, adjoined one to the other, the shaft guide being located forward of the pipe, faced forwardly and containing the shaft the proximate end of which is mounted therein and the distal end of which carries a deflector of conic-shape extending outwardly of said assembly and positioned with its sloped side facing inwardly toward the forward terminal end of said small diameter pipe, the pipe providing a chamber into which a stream of the liquid hydrocarbon fuel can be injected via an inlet at the rearward end of said pipe and discharged via an outlet at the forward end of the shaft guide, a large diameter pipe within which said small diameter pipe, and assembled shaft and shaft guide, is axially mounted, the diameter of the pipe being sufficient to form an annular chamber between the inside wall surface of said large diameter pipe and the external wall surface of said small diameter pipe, an inlet and outlet communicating with said annular chamber to provide a passageway, separate from that which carries the hydrocarbon liquid fuel, for carrying the oxygen, air or other oxygen-containing gas the improvement wherein the outlets of both the small diameter and large diameter pipes, respectively, form concentric annuli, are in close proximity, faced toward, and in a straight line with the inwardly facing sloping surface of the deflector to provide parallel flow paths for concentric tubular columns of the liquid hydrocarbon fuel, and the oxygen, or air or other oxygen-containing gas, ejected from the annular outlets of each of the pipes, respectively, so that both streams impact with the sloping surface near the apex of the cone of the deflector located at a distance outwardly of said assembly ranging from about 0.5 to about 5 times the diameter of the opening through which the oxygen, or air or other oxygen-containing gas, is ejected, and each stream forced outwardly from the apex of the cone to admix one stream with the other to form a combustible mixture which, on ignition, burns ex situ of the burner body.
