A device for preparation of a water-fuel emulsion comprises a blending chamber, as well as a fuel nozzle and a water nozzle for supply of respective mediums in the chamber. A nozzle that ensures boiling of water is used as the water nozzle. The water nozzle comprises an inlet and outlet sections that are respectively convergent and divergent in the direction of medium flow, between which the minimal cross-section of the nozzle is located. The generatrix of a fore part of the divergent section of the nozzle has a concave shape in relation to the axis of the nozzle in the critical cross-section of the nozzle. The water nozzle is located on a longitudinal axis of the chamber while the fuel nozzle is located in line with the water nozzle and is shaped as a ring enveloping an end part of the water nozzle.
