As illustrated in thedrawing, this invention is shown as embodied in a device adapted to be connected with conduits supplying respectively a liquid fuel and an atomizing avent such as compressed air or steam. heans are provided for the mixing of the two elements so that an eiicient atomization will occur, and such that will result. y Y

A pipe 1 connected to a lsource of fuel supply, not shown, and a pipe 2 connected to a source of air or steam supply, are secured to a fitting 3 by threaded connections. A cylindrical opening 4 and a cylindrical opening 5 in the fitting 3 are continua-tions respectively of the pipes or conduits land 2. The fitting 3 has a flat perpendicular face adapted to match the face of a fitting 6. `A cylindrical opening 7 through the fitting 6 registers lwith the opening 4 and an opening 8 of novel form registers with the opening 5. The opening 8 is substantially wider than its depth and has the form best shown in Fig. 5.

VThe fitting 6 has a perpendicular recess 10 registers with the opening 7 and an opening 11 registers with the opening 8. Grooves 12 form a communication between the recess 10 and the opening 11 whereby the fuel and the atomi'zing agent are co-mingled a long narrow hot flame Y fducedathrough.the. conduits 11 `and 2, respectively, and into the fitting 91 wherethey are mixed,`tl ie 'mixture passingli'nto the tube`f13 where its movement causes `the.;rotationo'f the face i adapted to match the face of a fitting 9.
