KAASUGENERAATTORIGAS GENERATOR
Tämän keksinnön kohteena on kaasugeneraattori, joka käsittää pääosin sylinte-5 rimäisen kaasuttimen rungon, arinan, jonka päälle poltettava, kiinteä polttoai-nemassa on syötetty, kaasuttimen runkoon muodostetun, poikkileikkaukseltaan muuta kaasutinta kapeamman kaasuttimen kurkun sekä kaasuttimen kurkun yläpuolelle kaasuttimen runkoon asennetut kaasutusilmasuuttimet.The present invention relates to a gas generator comprising mainly a cylindrical carburettor body, a grate onto which solid fuel to be burned is fed, a carburettor throat formed in the carburettor body, and a carburettor located above the throat of the carburettor.
10 Tunnetuissa kaasugeneraattoreissa kaasuttimen kurkku on poikkileikkaukseltaan vakio. Puhtaan tuotekaasun kehittymisen kannalta tämä ei kuitenkaan ole optimaalinen tilanne. Tehon tarpeen ollessa maksimissaan on edullista, että kaasuttimen kurkku läpäisee suuremman kaasuvirran kuin minimiteholla.10 In known gas generators, the throat of the carburettor has a constant cross-section. However, this is not an optimal situation for the development of pure product gas. When maximum power is required, it is preferable for the carburettor throat to pass a greater gas flow than the minimum power.
15 Eräs ennestään tunnettu kaasugeneraattori on esitetty Fl-patenttijulkaisussa 60884.A prior art gas generator is disclosed in Fl patent 60884.
Keksinnön tarkoituksena on aikaansaada kaasugeneraattori, jossa kaasuttimen kurkun poikkipinta-alaa voidaan säätää optimaalisesti palamisen kaasuttimen 20 toiminnan aikana. Keksinnössä kaasuttimen kurkun poikkipinnan muutos toteutetaan pystysuunnassa liikkuvalla säätöelimellä, erityisesti säätökartiolla. Kartion ollessa yläasennossa, kurkusta läpimenevä kaasuvirta pienenee vastaten kaasugeneraattorista otettavaa pienintä tehoa. Vastaavasti kartion ollessa ennalta säädetyssä ala-asennossa, suurempi määrä kaasua pääsee esteettö-25 mästi pelkistyshiilikerrosalueelle, mahdollistaen näin maksimitehon generaatto-. ’ · rista.It is an object of the invention to provide a gas generator in which the carburettor throat cross-section can be optimally adjusted during operation of the combustion carburettor 20. In the invention, the change of the carburettor throat cross-section is effected by a vertically movable adjusting member, in particular an adjusting cone. When the cone is in the up position, the gas flow through the throat is reduced corresponding to the minimum power drawn from the gas generator. Correspondingly, with the cone in a predetermined lower position, a greater amount of gas is freely accessible to the reduction carbon layer region, thereby enabling maximum power generation. '' List.
Keksinnön mukaiselle kaasugeneraattoriile on erityisesti tunnusomaista se, että kaasuttimen kurkun kohdalle on asennettu kaasuttimen sylinterimäisen rungon 30 kanssa olennaisesti samankeskinen, ylöspäin kapeneva kurkun poikkipinta-alan säätöelin.The gas generator damper according to the invention is characterized in that an upwardly tapering upwardly tapering throat cross-sectional adjusting member is mounted on the carburettor throat.
· Keksinnön eräälle edulliselle toteutusmuodolle on tunnusomaista se, että sää- .. .. töelimen muodostaa ylöspäin kapeneva kartio, joka on järjestetty pystysuun- 35 nassa liikutettavaksi.An advantageous embodiment of the invention is characterized in that the adjusting member is formed by an upwardly tapered cone arranged to be vertically movable.

Keksinnön eräälle toiselle edulliselle toteutusmuodolle on tunnusomaista se, että pystysuunnassa liikutettavan kartion akseli on järjestetty arinan läpi.Another preferred embodiment of the invention is characterized in that the axis of the conically movable cone is arranged through a grate.
Vielä eräälle keksinnön edulliselle toteutusmuodolle on tunnusomaista se, että 5 kartion akseli on yhdistetty arinaan, ja että akseli on järjestetty pyöritettäväksi siten, että myös arina pyörii.Yet another preferred embodiment of the invention is characterized in that the axis of the cone 5 is connected to the grate and that the axis is arranged to be rotatable so that the grate also rotates.
Keksinnön mukainen kaasugeneraattorin kaasutin mukautuu tehon tarpeeseen, säilyttäen aina optimikaasuvirtauksen ja -lämpötilan kaasuttimen kurkussa ja 10 luoden näin edellytykset mahdollisimman laadukkaan tuotekaasun kehittymiselle.The gas generator carburettor of the invention adapts to the need for power, always maintaining the optimum gas flow and temperature in the throat of the carburettor, thereby creating the conditions for the development of the highest quality product gas.
Seuraavassa keksintöä selitetään yksityiskohtaisemmin viittaamalla oheiseen piirustukseen, joka esittää leikkausta keksinnön mukaisen kaasugeneraattorin 15 kaasuttimesta.In the following, the invention will be explained in more detail with reference to the accompanying drawing, which shows a section through a carburettor of a gas generator 15 according to the invention.
Viitenumerolla 1 on merkitty kaasuttimen runkoa, joka on pääasiassa sylinteri-mäinen lukuunottamatta kaasuttimen kurkkua 6, jossa poikkileikkauksen pinta-ala on selvästi muuta kaasutinta pienempi. Kaasuttimen kurkku 6 sijaitsee ari-20 nan 2 yläpuolella. Kaasuttimessa poltetaan kiinteää polttoainemassaa 8. Viite-numerolla 3 on merkitty kaasutushiilipatjaa ja viitenumerolla 4 kaasutusil-masuuttimia, joita on jaettu tasaisesti kaasuttimen rungon ympäri. Kaasutusil-:' j · masuuttimien 4 yläpuolella on paloalue 7.Reference numeral 1 denotes a carburetor body which is substantially cylindrical except for the carburetor throat 6 where the cross-sectional area is clearly smaller than the other carburettor. The carburetor throat 6 is located above the Ari-20 nan 2. A solid fuel mass 8 is burned in the carburettor. Reference numeral 3 denotes a gasification carbon mattress and reference numeral 4 denotes gasification air nozzles evenly distributed around the carburettor body. There is a fire area 7 above the gasification nozzles 4 above the nozzles 4.
: 25 Kaasuttimen kurkun 6 kohdalle keskelle kaasutinta kaasuttimen pystyakselin ’· ·’ kanssa samanakselisesti on järjestetty kaasuttimen kurkun säätökartio 5. Kartio on ylöspäin kapeneva. Edullisesti metallista tai keraamisesta materiaalista valmistettu kartio on akseloitu akselin 9 välityksellä arinan 2 läpi. Akseliin 9 on yhdistetty edullisesti hydraulitoiminen mekanismi, joka liikuttaa kartiota 5 pysty-30 suunnassa kaasuttimen kurkun vapaan poikkipinta-alan säätämiseksi. Kartion ·’.'·! yläasennossa kurkusta läpimenevä kaasuvirta on pienimmillään vastaten kaa- sugeneraattorista otettavaa pienintä tehoa. Vastaavasti kartion ennalta sääde-... · tyssä ala-asennossa suurempi määrä kaasua pääsee esteettömästi pelkis- tyshiilikerrosalueelle, mikä mahdollistaa maksimitehon ottamisen kaasu-35 generaattorista.: 25 At the carburetor throat 6, the carburetor throat adjustment cone 5 is arranged in the center of the carburetor, parallel to the carburetor vertical axis '· ·'. Preferably, the cone made of metal or ceramic material is axed through the shaft 9 through the grate 2. Preferably, a shaft is provided with a hydraulic mechanism which moves the cone 5 vertically to 30 to adjust the free cross-sectional area of the carburettor throat. The cone · '.' ·! in the up position, the gas flow through the throat is at its lowest corresponding to the lowest power drawn from the gas generator. Correspondingly, in the lower cone predefined position, a greater amount of gas is unobstructed to enter the reduction carbon layer region, allowing maximum power to be drawn from the gas-35 generator.
