Abstract
The invention relates to an atomizer burner assembly for oil burners. The assembly has electric heating apparatus for maintaining a relatively constant temperature for the oil supply over a range of throughputs which may vary for different atomizer nozzles, for example, from 0.5 to 2.5 l/h. The heating apparatus includes a PTC resistor mounted in the supply pipe in series with a near zero temperature coefficient heating element which surrounds the supply pipe at a longitudinal position between the PTC resistor and the atomizer nozzle. The PTC resistor controls the heat generated by the heating element in accordance with the temperature of the throughput oil to maintain a constant temperature for the throughput oil.
