ABSTRACT OF THE DISCLOSURE There is disclosed a mechanised emulsifier for mixing water and hydrocarbon fuels for boilers and internal combustion engines. The emulsifier includes a housing affording a substantially annular mixing chamber. An annular rotor is mounted for rotation in the mixing chamber and is provided with a multiplicity of individual outwardly extending enclosed passages leading from inlet orifices of the rotor, disposed at or adjacent its axis of rotation, to outlets in the peripheral surface of the rotor and emerging therethrough. The ratio of the radial distance from the inlet to each passage to the outer surface of the rotor to the radius of the rotor is in the range of 0.4:1 to 0.9:1. Each passage affords at least one constriction to flow located inwardly of the peripheral surface of the rotor. An inlet chamber communicates with the inlet orifices in the rotor and is disposed at or adjacent the axis of rotation of the rotor. The inlet chamber is provided with an inlet for the fluids to be mixed. The mixing chamber has a circular outer wall extending around a major proportion of its circumference with a small clearance between the circular wall and the periphery of the rotor, the clearance being substantially constant throughout the major proportion of the circumference. The circular outer wall extends outwardly into a spiral shape so as to define a generally crescent shaped outlet region between the spiral shaped wall of the mixing chamber and the periphery of the rotor. The outlet region communicates with an outlet passage and drive means are arranged to onable the rotor to be rotated in the mixing chamber. The application also discloses a method of forming an emulsion which comprises subjecting a mixture of liquids to cavitation, followed by shearing and then turbulent flow.
