ABSTRACT:
A blue-flame oil burner including a flame-tube, a wall extending transvery of the flame-tube and defining the upstream end thereof, the wall having therein a metering orifice through which air enters the flame-tube, the orifice being the only air inlet into the flame-tube, an oil atomizing nozzle positioned upstream of the wall and discharging an oil spray through the orifice into the flame-tube, and a mixing tube positioned within the flame-tube co-axially of the orifice and having its upstream end spaced axially from the wall by a distance such that the peripheral area of the space between the wall and the upstream end of the mixing tube and defined within an imaginary upstream extension of the peripheral wall of the mixing tube to the transverse wall is between one and three times the difference between the cross-sectional area at the upstream end of the mixing tube and that at the orifice, the mixing tube having a length, L, and a diameter, D, such that the ratio L/D is between 1.0 and 1.75, and the flame tube having an equivalent ratio L/D of between 2.0 and 5.0.
