Abstract : A multifuel burner utilizing ultrasonic atomization was developed and demonstrated. Designed for use with a 100-watt thermoelectric generator, the burner must transfer heat at 7 w/sq. cm. to thermocouple junctions at 900 C, which is accomplished by heating a wire-screen mantle to 1075 C. Burning rate is 1 lb fuel/hr, or 18,000 Btu/hr, but the atomizer and burner design are suitable for burning rates to 50,000 Btu/hr. Fuel properties have no significant effect on performance when firing fuels ranging from aviation gasoline to No. 2 fuel oil, except that the fuel metering valve must be reset with changes in fuel viscosity. The burner is ignited electrically by momentary heating of a glow coil, and full heat output is generated immediately on ignition. Fuel is fed from a tank pressurized to 10 psi and metered with a manual valve; combustion air is supplied by a small fan. The ultrasonic atomizer requires 4 w at 12 v, and the fan requires 5 w. A 12-v battery is required for start-up and for operation until generator power is available. Weight of the demonstration burner is 2.5 lb. (Author)
