Description

“MAGNETIC RESONATOR SYSTEM FOR PAINT SHOPS”Field of Invention

[0001] The invention relates to magnetic resonator systems. It more particularly relates to magnetic resonator systems provided with thermal protection, that improve specific area of contact between fuels and air on tilization for improving combustion efficiency in paint curing ovens.Background of the Invention

[0002] Ordinarily, fuels are fed through paint shop’s burner nozzles without any additional sub-component being present in series or parallel with the flow line to ensure proper fuel tilization as it enters the combustion chamber. Conventionally atomization of the fuel is limited by dimensions of the nozzle and its metallurgy. It binds the combustion efficiency, thus limiting the mixing of Air and fuel and limiting emissions which is by product of combustion. This unresolved problem is garnering greater and greater attention of plant engineers as they try to get more output from every unit of fuel burnt. The need was non-invasive devise and non-chemical mixture to be added with the fuel, which improves fuel efficiency.

[0003] It is known that Hydrocarbon fuels have long branched geometric chains of carbon atoms, which have the tendency to fold over onto themselves and on adjoining molecules due to intermolecular electromagnetic attraction existing between like molecules or atoms, which is known as Vander Walls forces. When exposed to strong magnetic lines of force, weak intermolecular forces are fragmented, thus enabling the excitation of fuel clusters and ensuring the proper mixing of air and fuel. The excitation of fuel clusters this way can thus enable better atomization of fuels. Therefore, it can be stated that a system capable of carrying out polarization of liquid or gaseous hydrocarbon fuels can increase the fuel burning efficiency by subjecting the fuel flowing in containment vessels or conduits to a shaped uniform magnetic field having consistent directional flux.

[0004] The excitation of fuel by such a system would ensure proper mixing of air and fuel, contributing to improved specific consumption. Furthermore, as the specific area of contact between air and fuel is improved, the combustion rate alsoimproves. Thus, for the same quantity of input energy of fuel and air provided in a ratio, better heat output in terms of heat units would be achieved, even as other parameters stay the same. This would thereby greatly improve the tilization of inputs by conventional Hydrocarbon burning systems employed for heating water and curing paints in a paint shop. If such a system doesn’t need to be repaired or replaced often to deal with wear and tear issues, it can provide a great economic reason for installing it on newer machines and even existing ones to improve fuel efficiency and reduce pollution.Objects of the Invention

[0005] Therefore, it is an object of the invention to disclose a system that improves fuel efficiency by ensuring proper mixing of fuel and air on atomization of gaseous and liquid hydrocarbons through the paint shop’s burner nozzles.

[0006] It is another objective of the present invention to reduce pollution caused by incomplete combustion of fuels through the paint shop’s burner nozzles.

[0007] It is still another objective of the present invention to facilitate the proper combustion of fuels, thereby enabling the extraction of maximum heat and, hence, economic benefit from every unit of fuel burnt through the paint shop’s burner nozzles.

[0008] It is yet another objective of the present invention to provide a system that has a long life and requires very little maintenance; hence, it doesn’t need to be repaired or replaced very often.Summary of the Invention

[0009] The invention providing the stated benefits, i.e. the magnetic resonator system for paint shops, comprises of a first pair of magnetic material, a first pair of specialised housing, a second pair of magnetic material, a second pair of specialised housing, Aluminium mounting clamps, and conventional fastening means. The first pair of magnetic materials are accommodated within a first pair of specialised housing and are mounted on a fuel conduit with the help of mounting clamps.

Figure, 1 CC shows the cut-section the magnetic material (K2) as accommodated within the specialised housing (P2) along a plane A-A. The first pair of magnetic material (K1 ) that are accommodated within a first pair of specialised housing (P1 ), are mounted on a fuel conduit (F) with the help of Aluminium mounting clamps (S1 ) (refer to Figs.2A, 2B, 2C, 3A and 3B).

[0028] In the magnetic resonator system for paint shops (100), the specialized housing (P2) has a hollow cuboidal shape that is open along one of its largest sides to enable it to accommodate the magnetic material (K2) (refer to Figs 1A, 1 B and 1 C). The two smallest sides of this cuboidal shaped specialised housing (P2) have some material removed along their edge (J) facing said open largest side to give said edges (J) a V-shape.

[0029] In the magnetic resonator system for paint shops (100), the sets of first pair of magnetic material (K1 ) so mounted on fuel conduit (F) are both positioned at an angular displacement of 90 degrees with respect to the second pair of magnetic (K2), but along different planes displaced along the length of the fuel conduit (refer to Fig. 3A).

[0030] In the magnetic resonator system for paint shops (100), the second pair of magnetic material (K2), which form a repulsing pair (with like poles facing each other), are of double resonance type, and are preferably uncoated sintered strontium ferrite magnetic grade Y 30 H-2 material (refer to Figs. 1 B, 1 C, and 1 CC). The first pair of magnetic material (K1 ), which forms an attracting pair (with unlikepoles facing each other), is of magnetic memory type and is preferably Coated with Ni-Cu-Ni sintered Neodymium NdFeB grade N50M magnetic material (refer to Figs. 2B, 2C, and 2CC). The specialised housing (P1 and P2) are preferably made up of polypropylene (refer to Figs. 1 A, 2A, 1 C, 2C, 1 CC and 2CC).

[0031] In the magnetic resonator system for paint shops (100), the arrangement formed by the pair of magnetic material (K1 , K2), Aluminium mounting clamps (S1 , S2), conventional fastening means (M), specialised housings (P1 , P2) is ordinarily mounted no more than 2 inch from the end of the fuel conduit (F) where burner of the ovens utilised in the paint shop is connected (refer to Figs 4A, and 4B).

[0032] In the magnetic resonator system for paint shops (100), the pair of magnetic material (K2) having a uncoated sintered strontium ferrite magnetic material of Grade Y30 H-2, is housed in said specialised housings (P2) made up of polypropylene.

[0034] In the magnetic resonator system for paint shops (100), the ideal results are achieved only when Hydrocarbon fuel being used (and that is flowing through conduit (F)) in paint shops is selected from gaseous and liquid fuel, such as, natural gas, LPG, propane, high-speed diesel (HSD), fuel gas, heavy furnace oil, diesel, and naphtha. The number of pairs of magnetic materials (K1 , K2) (refer to Figs 4A and 4B) to be ideally provided on the fuel conduit (F) is determined based upon the length and circumference of the fuel conduit (F), mass flow rate of fuel in the conduit; and type of the fuel being used (liquid or gaseous).

[0035] In the magnetic resonator system for paint shops (100) (refer Figs. 4A and 4B) as ordinarily utilised in paint shop applications, the pairs of magnetic materials (K1 , K2) accommodated within said specialised housings (P1 , P2) on the fuel conduit (F) using Aluminium mounting clamps (S1 , S2), and conventional fastening means (M) are wrapped in heat insulation strips (T), with the heat insulation strips (T) being preferably made up of Teflon.

[0036] Referring to Figs 4A and 4B, it is stated that magnetic resonator system for paint shops (100), as ordinarily utilised in paint shop applications, the first pair of magnetic material positioned closest to the burner manifold (E) is always the pair of said magnetic material (K1 ) that are accommodated within the specialised housing (P1 ) and mounted on the fuel conduit (F) by utilising Aluminium mounting clamps (S1 ) and conventional fastening means (M). The subsequent basic repeating unit of the magnetic resonator system for paint shops (100) is as disclosed in Fig. 3A, with mounting of sub-components being avoided along sharp bends and with repetition continuing after the sharp bend in said fuel conduit (F) has ended if required. The subsequent basic repeating unit of the magnetic resonator system for paint shops (100) is as disclosed in Fig. 3A, is always rotated 90 degrees with respect to the previous basic repeating unit mounted on the fuel conduit (F). Figure 4B discloses the magnetic resonator system for paint shops (100), as ordinarily utilised in paint shop applications, where the magnetic materials (K1 , K2) (as represented by their respective the specialised housings (P1 , P2)) mounted on fuel conduit (F) along with their accompanying compliment of specialised housings (P1 , P2), the Aluminium mounting clamps (S1 , S2), and the conventional fastening means (M) are completely wrapped in heat insulation strip (T).

[0037] Figure 4A and 4B depict only one of many possible arrangements, with the actually utilised arrangements being dependent upon the factors such as the length and circumference of the fuel conduit (F), mass flow rate of fuel in the conduit; and type of the fuel being used (liquid or gaseous). Regardless of the utilised arrangement, the first pair of magnetic material positioned closest to the burner manifold (E) is always the pair of said magnetic material (K1 ) that are accommodated within the specialised housing (P1 ) and mounted on the fuelconduit (F) by utilising Aluminium mounting clamps (S1 ) and conventional fastening means (M).

[0038] When installed on the fuel conduit (F) for carrying fuel such as those selected from LPG, Naphtha, natural gas, HSD and any other liquid or gaseous hydrocarbon to the burner manifold (E) of the paint shop oven (refer to Figs. 4A and 4B), the configuration utillised involves, the use of three pairs of the magnetic material (K2) (repulsive pair) that are accommodated within their respective specialised housing (P2) and mounted on the fuel conduit (F) by utilising Aluminium mounting clamps (S2) and conventional fastening means (M), and the use of five magnetic material (K1 ) (attractive pair) that are accommodated within their respective specialised housing (P1 ) and mounted on the fuel conduit (F) by utilising Aluminium mounting clamps (S1 ) and conventional fastening means (M), with said magnetic materials (K1 , K2) being spaced from each other and arranged alternately one after another in series.

[0039] The magnetic resonator system for paint shops (100) (refer to Figs. 4A and 4B), so disclosed, works by polarizing the liquid or gaseous hydrocarbon flowing through fuel conduit (F), the resulting excitation of fuel clusters, thus enables better atomization and mixing of fuels at the burner manifold (E). This allows the magnetic resonator system for paint shops (100) to achieve all its stated objectives. The magnetic resonator system for paint shops (100), having been provided with heat insulation strips (T), is protected from surrounding heat, which allows the constituting magnetic materials (K1 and K2) to retain their functional effectiveness for a very long time. This reduces the need to replace the magnetic materials (K1 , K2) that would, over time, lose their magnetic properties due to heat exposure.
