摘要:
A fuel in microemulsion form, particularly for Diesel engines, comprising a primary fuel constituted by mineral oils and/or vegetable oils, water, a lipophilic emulsifying agent (W/O) and a hydrophilic emulsifying/detergent agent (O/W), wherein the hydrophilic emulsifying/detergent agent (O/W) is a mixture of two or more polyol esters having different molecular weights.

A fuel, particularly for Diesel engines, in microemulsion form, comprising a liquid fuel, an emulsifier and an emulsive agent, the emulsive agent having an HLB value higher than 9. The invention also relates to a method for preparing a fuel, particularly for Diesel engines, in microemulsion form, which comprises the mixing of a liquid fuel, particularly a liquid fuel for Diesel engines, an emulsifier and an emulsive agent, the emulsive agent having an HLB value of more than 9, and to a fuel which can be obtained by means of the method.
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:
An apparatus and a method for forming stabilized atomized microemulsions from different liquids which are normally immiscible; the apparatus according to the invention comprises a primary chamber (C1) and a sequence of at least two cavitation chambers (C2-C5) arranged in succession, means for feeding primary and secondary fluids into the primary chamber (C1), and means for the exit of the formed microemulsion from the last cavitation chamber (C5), the primary chamber (C1) and the cavitation chambers (C2-C5) being fluid-connected to each other by way of fluid passage means which are adapted to produce a velocity of the fluids, during passage through the passage means, which gradually increases from the primary chamber (C1) toward the last cavitation chamber (C5). The method according to the invention comprises the stage of premixing the primary fluid with the secondary fluid, followed by the passage of the premix of fluids through a succession of steps of flow at a higher velocity alternated with steps of flow at a lower velocity, the higher flow velocities gradually increasing from the first higher-velocity step to the last higher-velocity step.
摘要:
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.
