Definitions

• the present invention relates to an adjustable modular device for pre-treating fossil fuels in order to maximize combustion efficiency thereof.
• a device is applied upstream of the combustion chamber of engines or boilers to improve the combustion reaction efficiency in the engine or in the boiler, both being powered by a fossil fuel.
• Scientific studies have shown that application of temperature gradients and of magnetic fields to fossil fuels significantly improves the combustion efficiency and then the production of useful energy, with a result of a strong reduction of unburnt substances and unwanted exothennic reaction products, such as NOx, COx, PMx.
• the methods of generating magnetic fields are mainly two: by permanent magnets or by energized solenoids.
• the permanent magnets allow higher magnetic field intensities to be achieved, that unfortunately are not constant along the longitudinal axis; further they are not uniform at increased distance from the magnet, so that a gap of a few tenths of a millimeter results in a decay of more than half of the magnetic field intensity.
• the highest performing magnets have strong degradation of performance when temperature increases, e.g. Neodymium magnets have no effect with temperatures above 80 Celsius degrees. Still, the performances decrease in the presence of other strong magnetic fields. All above said makes not repeatable nor constant in time the nominal performances and, in addition, conditioned by environment. Therefore, the method by permanent magnets is unsuitable for industrial mass production.
• the solenoids As regards the method by solenoids supplied by current or voltage generators, i.e. accumulators or from the mains, the solenoids, as compared with the permanent magnets, effectively permit constant intensity magnetic fields to be created but they have physical limits due to the materials used and the overall dimensions. However, these limits can be overcome by configuring assemblies of multiple solenoids electrically interconnected in series or in parallel. They are therefore compatible with industrial mass productions and with the possibility of achieving high quality standards, and provide in a consistent and reproducible way constant performances that confirm the nominal data.
• the present devices for the pre-treatment of fuels mainly rely on the method by solenoids by adopting various solutions.
• a ventilation and cooling system which puts the fuel conduit in direct contact with air drawn from the outside environment; see WO2013/098705A1 (Campostrini), in which claim 1 claims a pre-treatment device that includes at least one channel forming an aeration chamber in open comrniinication with the outside environment; claim 2 specifies that provided at the inlet and outlet of the fuel conduit are flanges or closure heads of the device body, 1
• each of which is provided with at least one duct in direct communication with the outside and with the channel forming the aeration chamber that adopts the function of aeration gap between the fuel conduit and the electromagnetic field generator of the device.
• claim 3 states that the ends of the fuel conduit are fixed to the closure heads by means of devices adapted to allow their fixing to the supply line of the fuel, so as to form an integral part of said line.
• the inside of the conduit is made in such a way as to create a sort of undulating labyrinth-like path for the fuel which is repeatedly diverted relative to the longitudinal axis of the conduit of the device.
• WO2013/024094A1 (Buoninsegni and Magnini) discloses a container having inside a tank connected to a fuel conduit, in which a ferromagnetic core is disposed inside the tank, and a solenoid is located on the surface outside of the tank inside the container, so as to generate a magnetic field that magnetizes the ferromagnetic core.
• WO2004/003372A1 (Pandolfo) provides two internal fuel inlet-outlet chambers that are spaced the one from the other with calculation of bypass flows and consequent pressures.
• V power supply voltage [V]
• N number of turns
• an economizer for combustion devices consists of a tube preferably made of steel around which at least two solenoids, preferably four, side by side, are wrapped.
• the device comprises at least two solenoids connected in parallel to one another.
• the magnetic field generator is constituted by solenoids.
• the purpose of the present invention is to obtain a magnetic field as much as possible with a single solenoid for each module, voltage and current intensity being the same.
• a device for pre-treating fossil fuels consisting of a casing and a single solenoid that is contained inside the casing and is electtically powered from a source, such as the mains, an alternator or a group of accumulation, by means of the electronic control of the input current.
• a source such as the mains, an alternator or a group of accumulation
• Such single solenoid is dimensioned so as to obtain the maximum intensity of the magnetic field consistent with fundamental requirements such as safety for people and surrounding objects, a correct operation and supply of functional equipment, e.g. the vehicle lights supplied by the same external source of the device, the preservation of the physical characteristics of the device components, in order to prevent deterioration, damage or malfunction thereof.
• the operation and power supply of that single solenoid are controlled and regulated by a temperature sensor and a potentiometer.
• the temperature sensor stops the operation of the solenoid when a safety predetermined maximum temperature is reached, in order not to create an ignition if any of explosive mixtures or dangerous temperatures for equipments or people.
• the potentiometer limits the maximum current that can be absorbed by the device and gives the correct priorities of supply to another cooperating equipment, for the correct operation of the means or installations which are interlocked with, and supplied by the same external source.
• Existing devices do not allow the absorption of currents varying in function of the absorption of other cooperating utilities and equipment, while the device according to the present invention allows to systematically maximize the absorbed current, and then the magnetic field generated.
