For å bidra til å løse det problem som mange land To help solve the problem that many countries

■står overfor, nemlig avhengigheten av petroleum for energi-formål, har søkeren utviklet en anordning som omfatter en forgasser for å danne brennbar gass ved brenning av kull; for således å gi en gass som har meget høy brennverdi, sCm er fri for forurensninger, og som har en høy flammetempera-tur, slik at kullet kan benyttes meget effektivt og erstatte eller supplere brenselolje utvunnet av petroleum. ■faced, namely the dependence on petroleum for energy purposes, the applicant has developed a device comprising a gasifier to form combustible gas by burning coal; to thus give a gas which has a very high calorific value, sCm is free of contaminants, and which has a high flame temperature, so that the coal can be used very efficiently and replace or supplement fuel oil extracted from petroleum.

<1>Slikt utstyr, som er gjenstand for søkerens norskj patentsøknad nr. 81 2750, utgjøres av en kompakt forgasser som har et nedre luftinnløp under en rist hvor kull forbrennes, som oventil er forsynt med rør for utløp av den dannede gass, hvilket rør fører til et syklonfilter hvor forurensninger, rester og aske som stammer fra f orbrennirigs-prosessen, sentrifugeres og avsettes ved bunnen av en vann- <1>Such equipment, which is the subject of the applicant's Norwegian patent application no. 81 2750, consists of a compact carburettor which has a lower air inlet under a grate where coal is burned, which is provided with a pipe above for the outlet of the formed gas, which pipe leads to a cyclone filter where pollutants, residues and ash originating from the incinerator process are centrifuged and deposited at the bottom of a water

Denne forgasser er senere blitt forbedret ved hjelp av tilleggsutstyr som danner én sone som er i stand til å bevirke forbrenning av kullpulver, rester, aske og luft,;somj tidligere ble sentrifugert ut av filteret og avsatt på i bunnen av vannreservoaret, for således a danne en gass-prosent som sendes til ovnen hvor den forbrennes sammen mi ed This carburettor has later been improved by means of additional equipment which forms one zone capable of effecting the combustion of coal powder, residues, ash and air, which was previously centrifuged out of the filter and deposited on the bottom of the water reservoir, thus a form a gas percentage which is sent to the furnace where it is combusted together with mi ed

Denne forbedring er beskrevet i søkerens , norske patentsøknad nr. 81 2968. a more effective temperature when utilizing the elements; which were previously considered to be unusable (powder, residues, contaminants and ash), which are carried by compressed air j up to a venturi where a combustion zone is formed where the combustion takes place. This improvement is described in the applicant's Norwegian patent application no. 81 2968.

Den foreliggende oppfinnelse vedrører en drift- og styringsprosess for forgasseren, som utgjøres av nye og j viktige forbedringer som gir utstyret så godt som optimal funksjon og således gjør forgasseren mer effektiv, praktisk, økonomisk og meget fordelaktig. Disse forbedringer er båide.. The present invention relates to an operating and control process for the carburettor, which consists of new and important improvements which give the equipment almost optimal function and thus make the carburettor more efficient, practical, economical and very advantageous. These improvements are both..

nye og oppfinneriske.new and inventive.

Den nevnte fremgangsmåte drives av trykkluft og venturier (forøkningseffekt), gir enklere regulering (mindre rør) og eliminerer bevegelige deler, såsom vifter som vanlig-vis benyttes til å befordre luft. The aforementioned method is powered by compressed air and venturis (increasing effect), provides simpler regulation (smaller pipes) and eliminates moving parts, such as fans which are usually used to convey air.

Den tillater oppvarmning av trykkluften for således å øke volumet ved oppvarmning og forbedre., venturienes virkningsgrad. Den forbedrer forgasserens og brennerens respons i forbrenningsprosessen. It allows heating of the compressed air to thus increase the volume during heating and improve the efficiency of the venturi. It improves the response of the carburettor and the burner in the combustion process.

Bruk av to venturier for forgassingen, én for blåsingj og den annen for inhalering, gjør forgasseren isobarisk, sliki at den kan åpnes og fylles mens den er i funksjon. Using two venturis for the gasification, one for blowing and the other for inhalation, makes the gasifier isobaric, so that it can be opened and filled while in operation.

Bruk av en spesielt konstruert kompressor tillater energireduksjon og matning av flere funksjonssektorer i utstyret. Sammen med forvarmning av luften ved utløpet kan 1/3 av den mekaniske energi spares. The use of a specially designed compressor allows energy reduction and the feeding of several functional sectors in the equipment. Together with preheating the air at the outlet, 1/3 of the mechanical energy can be saved.

Forgasserens drift- og styreprosess ifølge oppfinnelsen medfører derfor en rekke fordeler. The carburettor's operating and control process according to the invention therefore entails a number of advantages.

Til bedre forståelse av oppfinnelsen skal den be- j skrives nærmere under henvisning til det utførelseseksempel i på oppfinnelsen som er vist på vedføyede tegning. j <' For a better understanding of the invention, it shall be described in more detail with reference to the embodiment of the invention shown in the attached drawing. j <'

Tegningen viser skjematisk og i snitt en trekull-forgasser og utstyr for forbrenning av den resulterende gass i med alternativ for oljeforbrenning, og omfatter drift- og styreutstyr ifølge oppfinnelsen. j På tegningen angir henvisningstall 1 en ovn med i ! The drawing shows schematically and in section a charcoal gasifier and equipment for burning the resulting gas with an alternative for oil combustion, and includes operating and control equipment according to the invention. j In the drawing, reference number 1 denotes an oven with i !

i skjer en forbrenning av pulverisert eller granulert kull.! in a combustion of pulverized or granulated coal takes place.!

Som det vil kunne ses av tegningen, tillater fore-<:>liggende fremgangsmåte at det rom som tidligere ble opptatt av den ildfaste utmuring 6 blir redusert til det halve, idet ildfast utmuring nå kun benyttes i den nedre del hvor for- . brenningen skjer, slik at det blir større plass i den øvre. J del for chargering. i As can be seen from the drawing, the present method allows the space that was previously occupied by the refractory masonry 6 to be reduced to half, as refractory masonry is now only used in the lower part where the the burning takes place, so that there is more space in the upper one. J part for charging. in

Henvisningstallet 7 betegner et rør som fører fra I en<i1>'inntaksanordning 8 i ovnen til et syklonfilter 9.. Gassen; som genereres i ovnen føres gjennom dette rør til filtereI t !i hvor den filtreres. I utløpet fra filteret befinner det- seg et grenrør 10 for installasjon av et trykkluftrør 11 som er anbragt inntil en venturi 12. Venturien fortsetter i en kanal 13 som er forbundet med den nedre del av ovnen, hvor luftkammeret og askerommet befinner seg.. .Dette arrangement utgjør ikke noen del av den foreliggende oppfinnelse, men er gjort til gjenstand for en tidligere søknad på forbedringer ved forgasseren. En av fordelene ved den foreliggende oppfinnelse består i innlemmelse av en varmeveksler 14 i forgasserutstyret, hvilken varmeveksler er installert mellom syklonfilteret 9 og brenneren 15. Røret 16, som fører filtrert gass fra I syklonfilteret er forbundet med varmeveksleren 14, som igjen er forbundet med tilførselsrøret 17 til brenneren 15, og | som danner en venturi 18. The reference number 7 denotes a pipe leading from an inlet device 8 in the oven to a cyclone filter 9. The gas; which is generated in the furnace is led through this pipe to the filtereI t !i where it is filtered. In the outlet from the filter there is a branch pipe 10 for the installation of a compressed air pipe 11 which is placed next to a venturi 12. The venturi continues in a channel 13 which is connected to the lower part of the oven, where the air chamber and ash chamber are located.. . This arrangement does not form any part of the present invention, but has been made the subject of an earlier application for improvements to the carburettor. One of the advantages of the present invention consists in the incorporation of a heat exchanger 14 in the carburettor equipment, which heat exchanger is installed between the cyclone filter 9 and the burner 15. The pipe 16, which carries filtered gas from the cyclone filter is connected to the heat exchanger 14, which in turn is connected to the supply pipe 17 to the burner 15, and | which forms a venturi 18.

Brenneren 15 er også koblet til rør 19 som tilfører luft for gassforbrenningen. (På den skjematiske tegning Jer systemet for alternativ fyring med olje utelatt fordi det ikke utgjør noen del av den foreliggende oppfinnelse). The burner 15 is also connected to pipe 19 which supplies air for the gas combustion. (On the schematic drawing, the system for alternative heating with oil is omitted because it does not form any part of the present invention).

Gjennom rørene 21 og 22, som danner en slags spiral ! inne i varmeveksleren 14, blir trykkluft oppvarmet før den j føres til blåseventurien 23, inhaleringsventurien 18 og for- j brenningsluftventurien 25, for således å øke trykkluftvolumet og forbedre venturienes virkningsgrad, i tillegg til å for- i bedre virkningen av forgasseren og brenneren. Through pipes 21 and 22, which form a kind of spiral! inside the heat exchanger 14, compressed air is heated before it is led to the blowing venturi 23, the inhalation venturi 18 and the combustion air venturi 25, in order to thus increase the compressed air volume and improve the efficiency of the venturis, in addition to improving the effectiveness of the carburettor and the burner.

Gjennom den samme kompressor og ved hjelp av rør 31 blir trykkluft tilført venturien 12, som resirkulerer kull-støv og aske under risten. Through the same compressor and by means of pipe 31, compressed air is supplied to the venturi 12, which recycles coal dust and ash under the grate.
