DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1, in accordance with the present invention there _l8 provided a fuel burner generally designated by he reference numeral 10 which is shown completely removed from its operating environment in a vapor generator. For the 75 ™L^hen^bUrner ’° ^inC‘^{udes a} cyHndrical conduit 12 which is nort U b^m°^Unte '^{n 3 cylindrical} «“ide tube 14, with a flange the cond^h n°foⁿr^{eCted in floW}_b^commu^ation at the end !f ^s=jsssi= drawing's °^{r y} °^{f COnduit 12}· ^{is not} *hotn * tie

As best shown in FIG. 3, the conduit 12 includes a cvlindri wllfeMand 22°b^{S?aCed 3Ρ}Γ¹ “ ^{OU,er wali 22}· ^withwalls 20 and 22 being joined together by a nozzle tin 24 tn form an annular gas chamber 26.
