摘要:
In a process for producing stable emulsions of at least two substantially immiscible fluids, particularly emulsions of a liquid fuel with water, a considerable increase in the efficiency of the emulsion-formation process is achieved by injecting the fluids to be emulsified into an emulsification chamber provided with an injection system which imparts to the fluids a motion in a direction which is substantially perpendicular to the general direction in which the fluids travel through the emulsification chamber. This injection system can be provided by means of a diffuser having an inlet hole, through which a stream of liquid is fed in a substantially axial direction, and at least one outlet hole, which leads into the chamber and whose axis lies on a plane which is substantially perpendicular to the direction of the inlet stream. In this manner, the stream strikes the walls of the emulsification chamber, producing a turbulent fluid motion which has a predominantly helical orientation and is capable of producing an efficient dispersion of one fluid in the other, forming dispersed-phase particles having an average diameter on the order of one micron or even less.

An electric stove, herein termed "Herna stove", comprising a metal footing (1), vertical walls (6) which are rigidly coupled to the footing and to each other, a top surface (10) for closing the stove which is fixed to the side walls, a heating cavity (5) which is delimited between the footing (1), the side walls and the top (10) of the stove, intake means (11) for aspirating air from the surrounding space into the stove, said means being arranged with an upward and downward orientation, a complex ventilation system (4) for aspirating/delivering ambient air through the air intake and discharge means, the ventilation system being arranged inside the heating chamber, possibly on the internal surface of the top structure with downward and upward flow directions, electric air heating means (7) arranged on the side walls toward the inside of the stove, means (3) for the forced evacuation of the air from the inside of the stove toward the surrounding space which are arranged in the footing.
摘要:
An apparatus is disclosed for emulsifying and atomizing fluid fuels with secondary fluids, in particular water, which has improved characteristics over commercially available apparata especially as regards the maximum mixable proportion of sec- ondaryfluid without undergoing efficiency deterioration, stability, and homogenization level. The apparatus comprises a first mechanical cavitation chamber wherein the fluid fuel and water are mixed and pretreated, a combined action cavitation chamber of a mechanical and electromagnetic type, and a final cavitation chamber, wherein homogenization of the fluid is completed. The combined actions within the intermediate chamber are achieved by generating within the chamber a centered corridor resulting from the effects of high pressures and vacua, and of an appropriate magnetic field. The invention also provides a method of treating fuel fluids by means of the apparatus illustrated.

摘要:
The present invention relates to a fuel for reducing the noxiousness of exhaust gases, particularly for internalcombustion engines. The fuel has the peculiarity of comprising a mixture of a fuel with 10 to 42% water with respect to the fuel, with the addition of a lubricating antifreeze activator in an amount comprised between 0.5 and 2% of the amount of fuel. The mixture is atomized and stabilized by means of a turbine transducer (8) which provides an electro-magneto-mechanical action, subjecting the mixture, in succession, to positive-pressure actions alternated with negative-pressure actions at high frequency.
