Opfindelsen angår en brænder til forgasning af finkornet til støvformigt fast brændstof, i hvilken det fra den dannede rågas tørre, udskilte flyvestøv føres tilbage til forgasning, omfattende en central tilfør-5 selsindretning for primæroxidationsmiddel og brændstof til indføring ved hjælp af en bæregas, en den centrale tilførselsindretning omgivende ringformet tilførselskanal for sekundæroxidationsmiddel samt en i centeraksen for den centrale tilførselsindretning anbragt rørformet 10 injektionslanse for indføring af flyvestøv i form af en flyvestøv/bæregasstrøm i kernen af den fra forgasningsbrænderen kommende brændstof/reaktionsmiddelstrøm.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a fine gasification gas burner for dusty solid fuel, in which the dry, separated exhaust dust from the formed raw gas is returned to gasification, comprising a central primary oxidizer supply device and fuel for introduction by means of a carrier gas. central supply device surrounding annular supply channel for secondary oxidizer and a tubular 10 injection lance located in the center axis of the central supply device for introducing fly dust in the form of a fly dust / carrier gas stream into the core of the gasification burner fuel / reaction stream.
Den grundlæggende opbygning af forgasningsbrænderen er symmetrisk. Forgasningen gennemføres som tryk-15 forgasning. Det faste brændstof er navnlig kul, koks, petroleumskoks og lignende. Som oxidationsmiddel anvendes navnlig oxygen og/eller luft samt i givet fald vanddamp. Bæregassen er en inert gas som eksempelvis kvælstof eller kuldioxid eller afstøvet rågas. I ud-20 trykket brændstof/reaktionsmiddelstråle betegner reaktionsmiddel såvel oxidationsmidlet som allerede opståede reaktionsprodukter og i givet fald også moderatorgas og bæregas. Den rågas, som forlader reaktoren medfører som bekendt flyvestøv, som eksempelvis medfører en 25 mængde på indtil 15 vægt% brændstof. Flyvestøvet fjernes fra rågassen ved hjælp af en passende afstøvnings-indretning. Bortskaffelsen af det er kostbar. For at bortskaffe flyvestøvet er det kendt at føre flyvestøvet tilbage til forgasningsprocessen. Dets brændstofandel 30 forbrændes derved og flyvestøvet indsmeltes iøvrigt. Indenfor rammerne af kendte forholdsregler (EP-B-0 072 457, EP-B-0 109 109) blandes flyvestøvet med det friske brændstof og tilføres sammen med brændstoffet forgasningsbrænderne. Det kræver imidlertid en særlig tilbe-35 redning af flyveasken med en omfangsrig og kompliceret teknisk indretning såvel som omfattende sikkerhedsfor- 2 DK 169526 B1 holdsregler. Porerummet eller hulrummet i flyvestøvet er fyldt med kulmonoxid- og hydrogenholdig rågas, som først må fortyndes til under faregrænsen, eller fjernes gennem flere skylninger og ompumpninger med inert gas.The basic structure of the gasification burner is symmetrical. The gasification is carried out as pressure gasification. The solid fuel is mainly coal, coke, petroleum coke and the like. In particular, oxygen and / or air as well as water vapor are used as oxidizing agents. The carrier gas is an inert gas such as nitrogen or carbon dioxide or dusted raw gas. In the expressed fuel / reaction jet, the reactant denotes both the oxidizing agent and reaction products which have already arisen and, where appropriate, also moderator gas and carrier gas. The raw gas leaving the reactor causes, as is known, flying dust, which, for example, results in up to 15% by weight of fuel. The fly dust is removed from the raw gas by a suitable dusting device. The disposal of it is costly. To dispose of the dust, it is known to return the dust to the gasification process. Its fuel portion 30 is thereby combusted and the fly dust is melted otherwise. Within the framework of known precautions (EP-B-0 072 457, EP-B-0 109 109) the fly dust is mixed with the fresh fuel and supplied with the fuel to the gasification burners. However, it requires a special preparation of the fly ash with a comprehensive and complicated technical device as well as comprehensive safety precautions. The pore space or cavity in the fly dust is filled with carbon monoxide and hydrogen-containing raw gas, which must first be diluted below the hazard limit, or removed through multiple inert gas flushes and repumps.
5 Også behandlingen af den fra flyvestøvet udtrukne rågas er omstændelig og kostbar, da den ofte er svovlholdig og af hensyn til miljøets beskyttelse hverken kan afbrændes eller forbrændes og udslippes i atmosfæren, løvrigt forstyrrer det, at det i det friske brændstof 10 indblandede flyvestøv reducerer brændstoffets varmevær-di, hvilket påvirker forgasningsprocessens termodynamik og reaktionskinetik. Det er også kendt at føre flyvestøvet tilbage til forgasningsreaktoren (DE-C2 909 008) og det gennem særlige, af forgasningsbrænderne gennem-15 trængte tilførselsdyser. Det skader forgasningsreaktionen og er næppe indført i praksis. I praksis er det sædvanligt (DE-B-2 325 204) at blæse flyvestøvet i en reaktor hen på slaggen, hvorved i almindelighed også restkulstoffet går ind i slaggen.5 The treatment of the raw gas extracted from the air dust is also cumbersome and expensive, since it is often sulfur-containing and, for the sake of the protection of the environment, cannot be burnt or burned and discharged into the atmosphere, it does not interfere with the reduction of the fuel contained in the fresh fuel 10. heat, which affects the thermodynamics and reaction kinetics of the gasification process. It is also known to return the fly dust to the gasification reactor (DE-C2 909 008) and the supply nozzles penetrated by the gasification burners. It damages the gasification reaction and is hardly put into practice. In practice, it is usual (DE-B-2 325 204) to blow the fly dust into a reactor on the slag, whereby generally the residual carbon also enters the slag.
20 Fra US-A-4 480 559 kendes en brænder af den ind ledningsvis omtalte art, i hvilken en som "char" betegnet substans, bestående af 50% kul og 50% flyvbaske, ved hjælp af luft som bæremiddel via en centralt arrangeret injektionslanse ledes ind i kernen af den fra 25 brænderen kommende kul/reaktionsmiddelstråle. Denne injektionslanse er omgivet af en ringformet tilførselskanal, gennem hvilken kullet sammen med primæroxidationsmidlet tilføres. Primæroxidationsmidlet tjener derved samtidig som transportmiddel for det faste brændstof.20 From US-A-4 480 559 there is known a burner of the kind referred to in the introduction, in which a substance referred to as "char" consisting of 50% coal and 50% fly ash, by means of air as a carrier via a centrally arranged injection lance is conducted into the core of the 25 burner coal / reactor jet. This injection lance is surrounded by an annular supply channel through which the charcoal is supplied with the primary oxidizer. The primary oxidant thus serves simultaneously as the vehicle for the solid fuel.
30 Oxidationsmiddelstrømmen må derfor afpasses således, at der sikres en sikker transport, og ikke kan ske tilbagetænding fra reaktionsrummet foran brænderen ind i brænderen. På grund af disse vanskeligheder er indstillingen af et for reaktionen optimalt mængdeforhold af 35 oxidationsmiddel og brændstof svært at opnå. Der er derudover det problem, at det via injektionslansen til- DK 169526 B1 3 førte "char" må forsynes tilstrækkeligt med oxidationsmiddel. Indsmeltningen af den deri indeholdte askedel nedsætter i betragtelig grad kulstofomsætningen af det med primæroxidationsmidlet tilførte brændstof.The oxidant flow must therefore be adjusted so that a safe transport is ensured and the reactor space in front of the burner cannot be ignited in the burner. Due to these difficulties, the setting of an optimum amount ratio of oxidant and fuel to the reaction is difficult to achieve. In addition, there is the problem that the "char" supplied via the injection lance must be adequately supplied with oxidizing agent. The melting of the ash contained therein significantly reduces the carbon conversion of the fuel supplied with the primary oxidizer.
5 Opfindelsen tilsigter at tilvejebringe en bræn der af den indledningsvis beskrevne art, hvor flyvestøvet når ind i forgasningsreaktorens reaktionszone uden at forstyrre forgasningsreaktionen, og hvor den i flyvestøvet indeholdte askedel kan indsmeltes til slagge 10 uden at hæmme den øvrige reaktion.The invention aims to provide a burner of the kind described initially, in which the fly dust reaches the reaction zone of the gasifier reactor without interfering with the gasification reaction, and wherein the ash contained in the fly dust can be melted into slag 10 without inhibiting the other reaction.
Formålet opnås med en brænder ifølge opfindelsen, som er særegen ved, at den centralt anbragte tilførselsindretning har en tilførselskanal for primæroxidationsmidlet og en denne omgivende brændstofringkanal 15 for det ved hjælp af en bæregas indførte brændstof, at injektionslansen er omgivet af en oxidationsmiddelkanal, og at denne er omgivet af tilførselskanalen for primæroxidationsmidlet, at oxidationsmiddelkanalen har en parallelt med forgasningsbrænderens akse forløbende 20 munding, at tilførselskanalen for primæroxidationsmidlet har en udad rettet munding og tilførselskanalen for sekundæroxidationsmidlet har en indad rettet munding, og at tilførselskanalen for sekundæroxidationsmidlet har flere ækvidistant langs omkredsen fordelte mun-2 5 dingsboringer.The object is achieved by a burner according to the invention, which is characterized in that the centrally located supply device has a supply channel for the primary oxidizer and a surrounding fuel ring channel 15 for the fuel introduced by means of a carrier gas, that the injection lance is surrounded by an oxidant channel. is surrounded by the supply channel of the primary oxidant, the oxidant channel has an orifice extending parallel to the axis of the gasification burner, -2 5 socket bores.
Opfindelsen udnytter den kendsgerning, at en af en forgasningsbrænder udtrædende brændstof/reaktions-middelstråle, navnlig en rotationssymmetrisk brændstof/ reaktionsmiddelstråle, i gasdynamisk henseende er meget 30 stabil og kan bære en flyveaskemængdestrøm ind i primærreaktionszonen. Forgasningsreaktionen begynder allerede i brændstof/reaktionsmiddelstrømmen og bliver her som i primærreaktionszonen ikke forstyrret af flyvestøvet, hvortil bidrager, at også dettes restkulstof bli-35 ver forgasset. Mængdestrømmen af flyvestøv må under alle omstændigheder ikke vælges for stor. Overraskende 4 DK 169526 B1 udføres der næppe mere flyvestøv fra primærreaktionszonen end sædvanlig og uden den beskrevne tilbageføring.The invention utilizes the fact that a gas / burner radiating fuel / reactor jet, in particular a rotationally symmetrical fuel / reactor jet, is highly dynamic in gas dynamics and can carry a fly ash flow into the primary reaction zone. The gasification reaction already begins in the fuel / reactant stream and here, as in the primary reaction zone, is not disturbed by the fly dust, which contributes to its residual carbon also being gasified. In any case, the flow of air from the dust must not be too high. Surprisingly, no more fly dust is produced from the primary reaction zone than usual and without the recirculation described.
Den øges ikke. En særlig flyvestøvsbortskaffelse er ikke mere krævet, når der arbejdes med brændere ifølge 5 opfindelsen. Flyvestøvet indsmeltes tværtimod til, slagge.It does not increase. Special fly dust disposal is no longer required when working with burners according to the invention. On the contrary, the dust is melted into slag.
I enkelthederne er der indenfor rammerne af opfindelsen flere muligheder for den videre opbygning og udformning. En foretrukket udførelsesform for opfindel-10 sen, som tillader en indstilling til forskellige driftsforhold, er ejendommelig ved, at injektionslansen og dermed dens munding kan forskydes i aksialretning.In the details, within the scope of the invention, there are several possibilities for the further construction and design. A preferred embodiment of the invention which permits a setting for different operating conditions is characterized in that the injection lance and hence its mouth can be displaced in the axial direction.
Det er endvidere en fordel at indrette en kølekanal mellem ringkanalen for primæroxidationsmidlet og 15 brændstof ringkanalen. En yderligere foretrukken udførelsesform for opfindelsen er ejendommelig ved, at injektionslansen, oxidationsmiddelkanalen, tilførselskanalen for primæroxidationsmidlet og kølekanalen danner et enkelt konstruktionselement, som gennem kølekanalen 20 er adskilt fra de øvrige konstruktionsdele af forgasningsbrænderen, og at dette enkelte konstruktionselement kan forskydes i aksial retning.It is further advantageous to provide a cooling duct between the ring duct of the primary oxidizer and the fuel ring duct. A further preferred embodiment of the invention is characterized in that the injection lance, the oxidant channel, the primary oxidizer supply channel and the cooling channel form a single structural element which is separated through the cooling channel 20 from the other structural parts of the gasification burner, and that this single structural element can displace in the direction of movement.
Indenfor opfindelsens rammer må som nævnt ikke indføres en for stor flyvestøvsmængdestrøm i forgas-25 ningsbrænderen. Ikke desto mindre er indstillinger indenfor et stort område mulige. En foretrukken udførelsesform er i denne sammenhæng ejendommelig ved, at injektionslansen er indrettet til tilførsel af en flyvestøvsmængdestrøm, som er en faktor 0,01 til.0,15 mindre 30 end brændstofmængdestrømmen. Indenfor dette område kan , i almindelighed tilbageføres den samlede ved anlægget til forgasnings af finkornet til støvformet fast brændstof opståede mængde flyvestøv med dets andel af brændstof.Within the scope of the invention, as mentioned above, an excessive flow of dust dust flow must not be introduced into the gasification burner. Nevertheless, settings within a wide range are possible. A preferred embodiment in this connection is characterized in that the injection lance is adapted to supply an airflow flow rate which is a factor of 0.01 to 0.15 less than the fuel flow rate. Within this range, generally, the total amount of fly dust generated by the gasification of the fine grain to dusty solid fuel can be traced back to its proportion of fuel.
35 Opfindelsen vil i det følgende blive forklaret nærmere ved hjælp af et udførelseseksempel med henvisning til tegningen, på hvilken DK 169526 B1 5 fig. 1 er et aksialsnit gennem en brænder ifølge opfindelsen, og fig. 2 et delvist frontbillede af brænderen i fig. 1.The invention will now be explained in more detail with the aid of an exemplary embodiment with reference to the drawing, in which FIG. 1 is an axial section through a burner according to the invention; and FIG. 2 is a partial front view of the burner of FIG. First
5 Den i figurerne viste brænder er til et ikke vist anlæg til forgasning af finkornet til støvformet fast brændstof. Anlægget har en forgasningsreaktor.5 The burner shown in the figures is for a plant not shown for gasifying the fine grain for dusty solid fuel. The plant has a gasification reactor.
Flere brændere brænder med deres brændstof/reaktions-middelstråle ind i forgasningsreaktoren og er dertil i 10 almindelighed fordelt i samme højde, ækvidistant langs omkredsen af forgasningsreaktoren. Brændstof/reaktionsmiddelstrålerne danner i forgasningsreaktoren en primær reaktionszone med forhøjet temperatur. Det forstås, at der fra forgasningsreaktoren udtages en rågas.Several burners burn with their fuel / reactor jet into the gasification reactor and are generally distributed at the same height, equidistant along the circumference of the gasification reactor. The fuel / reactant jets form a primary reaction zone with elevated temperature in the gasification reactor. It is understood that a crude gas is extracted from the gasification reactor.
15 Til den grundlæggende opbygning af brænderen ifølge opfindelsen hører en første tilførselskanal 1 til primæroxidationsmidlet, en omgivende brændstofring-kanal 2 til brændstoffet, som indføres med en bæregas, en brændstof-ringkanalen 2 omgivende, anden, ringfor-20 met tilførselskanal 3 til sekundæroxidationsmiddel og kølekanaler 4 samt i givet fald mindst én moderator-gasringkanal 5.15 The basic structure of the burner according to the invention includes a first supply channel 1 for the primary oxidant, a surrounding fuel ring channel 2 for the fuel introduced with a carrier gas, a fuel ring channel 2 surrounding it, a second ring-shaped supply channel 3 for secondary oxidant and cooling ducts 4 and at least one moderator gas ring duct 5.
I den første tilførselskanal 1 befinder sig en rørformet injektionslanse 6, omkring hvilken strømmer 25 oxidationsmiddel. Gennem injektionslansen 6 kan ind i kernen af brændstof/reaktionsmiddelstrålen injiceres en flyvestøv/bæregasstrøm. Bæregassen er eksempelvis rågas. I udførelseseksemplet udmunder injektionslansen 6 i området ved udmundingerne af den første tilførselska-30 nal 1, brændstof-ringkanalen 2 og den anden tilførselskanal 3 og dermed så at sige i fronten af forgasningsbrænderen. Der anvendes en tragtformet udformning. Injektionslansen 6 forløber i forgasningsbrænderens akse. Den kan være aksial forskydelig i retning af den 35 på tegningen viste dobbeltpil, hvilket tillader en tilpasning til forskellige driftsforhold.In the first supply channel 1 is a tubular injection lance 6, around which flows oxidant. Through the injection lance 6, a fly dust / carrier gas stream can be injected into the core of the fuel / reaction jet. The carrier gas, for example, is raw gas. In the exemplary embodiment, the injection lance 6 in the area at the mouths of the first supply channel 1, the fuel ring channel 2 and the second supply channel 3 opens, and so to say, in the front of the gasification burner. A funnel-shaped design is used. The injection lance 6 extends in the gasifier burner axis. It may be axially displaceable in the direction of the double arrow shown in the drawing, allowing an adaptation to different operating conditions.

Ifølge opfindelsen er injektionslansen 6 omgivet af en oxidationsmiddelkanal 7, og denne er omgivet af den første tilførselskanal 1. Derved har oxidationsmiddelkanalen 7 en munding 8, som er rettet parallelt 5 med forgasningsbrænderens akse, og tilsvarende træder oxidationsmidlet ud af en oxidationskanal og omhyller flyvestøvsmængdestrømmen. Den første tilførselskanal 1 har derimod en udad rettet munding 9. Mundingen 10 af den anden tilførselskanal 3 er derimod rettet indad, 10 hvor den anden tilførselskanal 3 er forsynet med flere ækvidistant langs omkredsen fordelte mundingsboringer 11, som det er antydet i fig. 2. løvrigt er alle mundinger udformet som ringspalter. Mellem den første tilførselskanal 1 og brændstof-ringkanalen 2 befinder 15 sig en ringformet kølekanal 4. Der er antydet en flammeovervåger 12, ved hjælp af hvilken forgasningsbrænderen kan overvåges på i og for sig kendt måde. Der findes en ydre kølekappe 13 med yderligere kølekanaler 4. Det ligger indenfor rammerne af- opfindelsen, at 20 der ved injektionslansen 6 er indrettet en isoleret tændelektrode 14, som det er antydet med prikstiplet linie ved mundingen af injektionslansen 6.According to the invention, the injection lance 6 is surrounded by an oxidizing channel 7 and this is surrounded by the first supply channel 1. Thus, the oxidizing channel 7 has an orifice 8 which is aligned parallel to the axis of the gasification burner, and correspondingly the oxidizing agent exits an oxidation channel and encloses the flow of dust dust. In contrast, the first supply channel 1 has an outwardly directed orifice 9. The orifice 10 of the second supply channel 3 is inwardly directed 10, the second supply channel 3 being provided with several equidistant orifice bores 11, as indicated in FIG. 2. deciduous, all orifices are designed as ring slots. Between the first supply duct 1 and the fuel ring duct 2 is an annular cooling duct 4. There is indicated a flame monitor 12 by which the gasification burner can be monitored in a manner known per se. There is an outer cooling jacket 13 with additional cooling channels 4. It is within the scope of the invention that an injection ignition electrode 14 is provided at the injection lance 6, as indicated by a dotted line at the mouth of the injection lance 6.
I en foretrukket udførelsesform for opfindelsen befinder inkektionslansen 6, oxidationsmiddelkanalen 25 7, den første tilførselskanal 1 og kølekanalen 4 sig i et eller ved et enkelt konstruktionselement, som i fig. 1 er vist med tæt skravering og kan forskydes i aksial retning. For såvidt består brænderen ifølge opfindelsen på en måde af to selvstændige konstruktions-30 grupper, som også kan udskiftes. Gennem udskiftningen er en tilpasning til forskellige driftsforhold mulig.In a preferred embodiment of the invention, the injection lance 6, the oxidant channel 25 7, the first supply channel 1 and the cooling channel 4 are located in one or by a single structural element, as in FIG. 1 is shown with close shading and can be displaced in the axial direction. In so far, the burner according to the invention consists in a manner of two independent structural groups which can also be replaced. Through the replacement, an adaptation to different operating conditions is possible.
Det til forgasningen af det finkornede til støvformede brændstof krævede oxidationsmiddel oxygen bliver fordelt i to strømme, det primære og det sekundære 35 forgasningsoxygen, hvis mængdeforhold primær til sekundær kan andrage 1:1,15 til 1,3. Indretningen erThe oxidizing agent oxygen required for the gasification of the fine-grained to dusty fuel is distributed in two streams, the primary and the secondary gasification oxygen, the ratio of primary to secondary being 1: 1.15 to 1.3.
