Description

Foreliggende oppfinnelse angår en anordning for forbehandling av petroleumbasert brennstoff før forbrenning, ifølge kravinnledningen. The present invention relates to a device for the pretreatment of petroleum-based fuel before combustion, according to the preamble.

Det er kjent at det oppnås en økt virkningsgrad ved forbrenning av forstøvet petroleumbasert brennstoff ved å føre brennstoffet gjennom en magnetfelt kort før forstøvingen. Med den økte virkningsgrad oppnås en resulterende drivstoffbesparelse og derav følgende redusert utslipp av forurensninger. It is known that an increased degree of efficiency is achieved when burning atomized petroleum-based fuel by passing the fuel through a magnetic field shortly before atomization. With the increased efficiency, a resulting fuel saving is achieved and the resulting reduced emission of pollutants.

I GB 2 155 993 beskrives anbringelse av magneter i en hylse som gjennomstrømmes av drivstoff, slik at magnetfeltets retning forløper i rett vinkel til drivstoffets strømningsret-ning. GB 2 155 993 describes the placement of magnets in a sleeve through which fuel flows, so that the direction of the magnetic field runs at right angles to the direction of flow of the fuel.

Den teoretiske forklaring av den prosess som foregår har det hittil ikke vært mulig å fremlegge, mens prosessen er godt belagt empirisk. The theoretical explanation of the process that takes place has so far not been possible to present, while the process is well documented empirically.

Basert på denne basiskunnskap har det imidlertid lykkes å oppnå en ytterligere økning av virkningsgraden med anordningen ifølge foreliggende oppfinnelse, slik den er definert med de i kravet anførte trekk. Based on this basic knowledge, however, it has succeeded in achieving a further increase in the efficiency with the device according to the present invention, as it is defined with the features stated in the claim.

Det er funnet at det oppnås en betydelig forbedring i forhold til kjent teknikk ved bruk av turbulent strømning av brennstoff i et magnetfelt med en feltstyrke i størrelsesordenen over 5 000, fortrinnsvis mellom 5 000 og 6 000 gauss. It has been found that a significant improvement is achieved compared to the prior art by using turbulent flow of fuel in a magnetic field with a field strength of the order of magnitude above 5,000, preferably between 5,000 and 6,000 gauss.

Tegningens figurer 1 og 2 viser to utførelser av anordningen ifølge foreliggende oppfinnelse. Figures 1 and 2 of the drawing show two embodiments of the device according to the present invention.

Brennstoffet føres inn gjennom inntaket 1 i inntaksstussen 10 og fordeles herfra til å passere radialt gjennom et gap hvis i det minste ene begrensning er dannet av en polsko 6 som er forbundet med en magnet 5. The fuel is introduced through the intake 1 into the intake nozzle 10 and is distributed from here to pass radially through a gap if at least one limitation is formed by a pole shoe 6 which is connected to a magnet 5.

Ved gjennomstrømning gjennom gapet 3 utsettes brennstoffet for en feltstyrke på 5 000 til 6 000 gauss og strømmer deretter videre til uttaksstussens 9 uttak 4. Inntaksstussen 10 og uttaksstussen 9 er forbundet med en hylse 7 og avtettet mot hylsen med 0-ringer 8. When flowing through the gap 3, the fuel is exposed to a field strength of 5,000 to 6,000 gauss and then flows on to the outlet 4 of the outlet nozzle 9. The inlet nozzle 10 and the outlet nozzle 9 are connected by a sleeve 7 and sealed against the sleeve with O-rings 8.

Gapet 3 er fortrinnsvis slik utformet at det tvangsmes-sig oppstår turbulens av brennstoffet, noe som kan oppnås med en hensiktsmessig utforming av polskoens 6 perifere kant. Dette kan eventuelt også oppnås ved innsetting av en spesielt utformet ring eller brikke på innsiden av hylsen 7 radialt ut fra polskoen.Herved sikres at det dannes turbulens i brennstoffet i det øyeblikk brennstoffet trenger inn i gapet og at strømningen gjennom gapet likeledes er turbulent. The gap 3 is preferably designed in such a way that turbulence of the fuel is forced to occur, which can be achieved with an appropriate design of the peripheral edge of the pole shoe 6. This can possibly also be achieved by inserting a specially designed ring or piece on the inside of the sleeve 7 radially outward from the pole shoe. This ensures that turbulence is formed in the fuel at the moment the fuel penetrates the gap and that the flow through the gap is likewise turbulent.
