An oil-water emulsifier comprises a Venturi member having an inlet for receiving oil, an oil-water emulsion outlet and an opening extending therethrough from the inlet to the outlet. The opening of the Venturi member comprises a diameter-reducing portion which connects to a throat portion having a substantially smaller diameter than the inlet, the throat portion being connected to an expanding portion extending from the throat to the outlet, the diameter of the outlet of the opening being substantially greater than that of the throat portion. A plurality of water injection holes extend from the outer periphery of the Venturi member to the throat portion so as to be in communication with the oil flowing through the throat portion, the injection holes being preferably substantially perpendicular to the direction of oil flow through the throat portion. Also disclosed is an oil-burner boiler system incorporating the above-described oil-water emulsifier.

In an improved oil-burning heat-producing system which has a rated maximum firing rate and which includes a firebox, means supplying fuel-oil under pressure, means supplying admix water under pressure, an emulsifier for emulsifying said water into said oil in the form of small droplets, an atomizing burner adapted to atomize said water-in-oil emulsion into tiny globules in air and to project said atomized emulsion into said firebox, whereby water globules which contain one or more droplets become still more finely atomized by the rapid vaporization of said droplets, the improvement wherein said emulsifier has: an approximately cylindrical oil-flow constraining throat D centimeters in diameter carrying the flowing fuel oil in a given flow direction therethrough, said throat being located between smoothly converging and smoothly diverging generally conical flow surfaces which are substantially symmetrical relative to said throat; means in communication with said smoothly converging flow surface for imparting swirling movement to the oil flow in a direction at an angle to said given flow direction before said flowing fuel oil reaches said throat; and a multiplicity n of water-injection holes in said throat, each water-injection hole having a smaller diameter of d centimeters than said throat diameter, each of said water injection holes extending approximately radially to said throat; the combined areas (0.25p2) of said n water-injection holes being 0.075 to 0.30 times the total area (0.25p2) of said oil-flow throat.
