654,200. Lighting burners. SMITH, G. D. Sept. 7, 1948, No. 23477. Convention date, Sept. 8,1947. [Class 75(iii)] A burner from which fuel normally flows in a cone of a predetermined angle, but initially on starting up flows momentarily in a cone of a wider angle, is combined with an igniter having a cavity or recess therein disposed with its open end in proximity to and directed toward the burner, and within said wider angle but outside of said predetermined angle, a fuel igniter element being disposed in said cavity, and when the burner is started fuel is projected into the said cavity or recess to be ignited by the igniter element, the ignited fuel then flashing back to ignite the fuel stream flowing from the burner, and, after ignition the burning fuel normally will flow out of contact with the igniter. A burner 15 for use in fog dispersal is ignited by an electric heating element 12 disposed in a recess 55 beneath a protecting cover 21 at the top of a hollow column 13 through which passes electric supply leads 60, 61. The burner 15 is adapted to discharge dispersed liquid or gaseous fuel initially in a cone 40 of wide angle to be ignited by the heating element 12. and, after ignition and when the inertia of the fuel has been overcome, to discharge said fuel in a cone 50 of smaller angle so that the flame does not contact the igniter element 12.
