I figurerna. 1 och 2 betecknar 1 ett tryckkärl som omsluter en brännkaxnmare 2 med en fluidiserad bädd 3. I denna. finnes en rör-slinga. 4 som omges av bäddmate- rialet.In the figures. 1 and 2, 1 denotes a pressure vessel enclosing a combustion chamber 2 with a fluidized bed 3. In it. there is a pipe loop. 4 which is surrounded by the bed material.
.Anläggningene gasturbindel innehåller en högtrycksturbin 6 som driver en hög»- tryckskompressor 5 och en med turbineu seriekopplad lågtrycksturbin 7 som driver en lågtryckskompressor 8. En startmotor 10 är kopplad till högtryckskompressorn. I ledningen 11 mellan lågtryckskompressom 8 och högtryckkompressom 5 finnes en 10 15 V0 \J1 8007214--3 mellanlqrlare 12. Vidare finnes en kraftturbin 13, som driver en generator 19.The gas turbine part plants contain a high-pressure turbine 6 which drives a high-pressure compressor 5 and a low-pressure turbine 7 connected in series with a turbine which drives a low-pressure compressor 8. A starter motor 10 is connected to the high-pressure compressor. In the line 11 between the low-pressure compressor 8 and the high-pressure compressor 5 there is an intermediate generator 12. Furthermore, there is a power turbine 13, which drives a generator 19.
Högtryckskompressorn 5 är ansluten till tryckkäxrlet 1 med en ledning 14. Brännkauzrnaren 2 är på. sin utloppssida förbunden med en hög-trycks- turbin 6 med en ledning 15. Mellan ledningarna 14 och 15 finnes en ledning 16 med en ventil 17, genom vilken kompressor-luft kan blandas med förbränningsgaser i och för reglering av anläggningens effekt. Högtrycksturbinen 6 och lågtrycks- tnrbinen 7 är förbundna med varandra genom ledningen 18. Lågtrycksturbinen 7 är förbunden med ln-aftturbinen 15 med en ledning 20. Ãngturbindelen innehåller en ångturbin 21 som driver en generator 22. Kondensat från turbinens 21 kondensor 22 pumpas av matarvattenpumpen 25 genom ledningen 24 till matarvattenförväzmaren 25 och lades därefter genom ledningen 26 till rörslingan 4 i brännkammaren 2. Här genereras ånga. som föras till turbinen 21 genom ledningen 27. Avgaserna från kraftturbinen 15 ledas till matarvattenför» värmaren 2§ genom ledningen 28.The high-pressure compressor 5 is connected to the pressure nozzle 1 with a line 14. The burner 2 is on. its outlet side is connected to a high-pressure turbine 6 by a line 15. Between the lines 14 and 15 there is a line 16 with a valve 17, through which compressor air can be mixed with combustion gases in order to regulate the power of the plant. The high pressure turbine 6 and the low pressure turbine 7 are connected to each other through the line 18. The low pressure turbine 7 is connected to the inlet turbine 15 by a line 20. The steam turbine part contains a steam turbine 21 which drives a generator 22. Condensate from the turbine 21 condenser 22 is pumped by the feed water pump 25 through the line 24 to the feed water pre-heater 25 and was then laid through the line 26 to the pipe loop 4 in the combustion chamber 2. Steam is generated here. which is fed to the turbine 21 through the line 27. The exhaust gases from the power turbine 15 are led to the feed water for the heater 2§ through the line 28.
Brännkammaren 2 uppdelar tryckloärlet 1 i två skilda rum 30 och 31. Komprimerad luft från högtryckskompressorn tillföras det undre rummet 50 och inblåses genom muzzstyoken 32 i brännkammaren 2 och håller bäddmaterialet i bädden 5 i fluidi- ser-at tillstånd. Bränsle tillföras genom ledningen 53. En tryoksatt vattenbehål- lars 54 står genom en ledning 35 med en regler-ventil 56 i förbindelse med mun- stycken 57 Genom vilka vatten kan sprutas direkt in i bädden 5 och därvid vid sin förångning kyla bädden 3. Vatteninspzutning regleras i beroende av bädd- temperatvren. En givare 58 känner temperaturen och en signal påföres reglerdcnet 40 *fia ledninæn 41. I beroende av denna signal reglerar donet 40 ventilen 56 och därmed den mängd vatten som tillföras bädden. Givaren 58 kan vara placerad i eller ovanför bädden 5, eftersom förbränningsgaser som lämnar bädden 3 har ungefär samma temperatur som denna.The combustion chamber 2 divides the pressure vessel 1 into two separate chambers 30 and 31. Compressed air from the high-pressure compressor is supplied to the lower chamber 50 and is blown in through the muzzstyok 32 in the combustion chamber 2 and keeps the bed material in the bed 5 in a fluidized state. Fuel is supplied through the line 53. A pressurized water tank 54 stands through a line 35 with a control valve 56 in connection with nozzles 57 Through which water can be sprayed directly into the bed 5 and thereby on its evaporation cool the bed 3. Water injection regulated depending on the bed temperatures. A sensor 58 senses the temperature and a signal is applied to the controller 40 * via the line 41. Depending on this signal, the device 40 controls the valve 56 and thus the amount of water supplied to the bed. The sensor 58 may be located in or above the bed 5, since the combustion gases leaving the bed 3 have approximately the same temperature as this.
Hög verkningsgrad i en kombinerad gas-ångcykelaxzläggzaing av beskrivet slag med förbränning i en fluidiserad bädd vid förhöjt tryck, 10-16 bar, är en anledning till det stora intresset för denna. En total systemverkningsgrad av över 40 % kan uppnås. En annan fördel är att förbränning kan ske vid låg temperatur, 800-850°C, så. att smältaska kan undvikas. Partiklar som medföljer förbrän- ningsgaser från bädden är "torra" och har därför ej tendens att klibba fast i en reningsanläggzzing t ex av oyklontyp. För gasturbiner tillräcklig effektiv rening kan åstadkommas och ringa risk för avsättningar på. turbinskovlar föreligger.High efficiency in a combined gas-vapor cycle accelerator of the type described with combustion in a fluidized bed at elevated pressure, 10-16 bar, is a reason for the great interest in this. A total system efficiency of over 40% can be achieved. Another advantage is that combustion can take place at low temperature, 800-850 ° C, so. that melt ash can be avoided. Particles that accompany combustion gases from the bed are "dry" and therefore do not have a tendency to stick to a treatment plant, for example of the oyclone type. For gas turbines, sufficiently efficient purification can be achieved and reduce the risk of deposits. turbine blades are available.
Ytterligare en fördel är att svavel i bränslet kan reagera "torrt" med ett lämp- ligt valt bäddmaterial, t ex dolomit, och därigenom absorberas av detta under bildning av gip och avlägsnas tillsammans med aska från bränslet och förbrukat bäddmaterial. Spridning av svavelföreningar med rökgaserna. kan således förhindras 10 15 20 25 35 soo?21a~s 4 En särskilt stor fördel är att kol kan förbrännas mllständigt vid så. låg temperatur som 800=850°C., Att temperaturen i den fluidiserade bädden måste hållas inom snäva. gränser inne- bär vissa problem som emellertid kan undanröjas genom uppfinningen, Fig; 5 illu- strerar detta. Bäddens 3 temperatur bör hållas inom intervallet A43.. Inom inter- vallet B-C kan förbränning upprëtthållas men minskar absorptionen av svavel och turbineffekt och sjunker verlmingsgraden. över nivån A smälter aska, som kan bilda klumpar som sätter igen luft och brëlnslemunstycken eller som kan bilda droppar som följer med förbränningsgaserna och som avsätter sig i renare och på. hmbinskovlæ. Ilär omgivningstemperamzren sjmker under den s k utläggnings- temperaturen '29 och luftens täthet och därmed massflödet genom kompressorerna ökar, 25% den syre som står till förfogande för förbräïnning. Detta. syre kan endast till en mycket ringa del utnyttjas för förbränning av en ökad mängd bränsle om ej kylning av bädden kan ökas. Ängslingans lcyleffekt är i stort sett konstant och ökad förbfinning medför attbäddons temperatur snabbt stiger till otillåten nivå., Luftöverskottsfaktorn stiger på sätt som illustreras i rig 4. På vertikala axeln har avsatts luftöverskottsfaktorn Ä och på den horison- tella axeln ytterlufttemperaturen T. Den s k utläggningspunkten To = +50°C. Vid utläggníngstemperattzren är Ä = 1,5. vid Ä understigande 1,5 blir atmosfären i bädden reducerande och erhålles korrosion på. tuber i bädden. Å = 1,5 är således den. lägsta. luftöverskottsfektor som kan tillåtas. Utan ökad lwlning kan :inte tillförseln av bränsle ökas i proportion till den syremängd som står till för- fogande vid temperaturer under To. Värdet på Ä stiger som den lutande hel- dragna linjen A63 visarQVid temperaturer över To måste bränsletillförseln minska för att Å ej skall understiga t ex Å min = 1,5. Reducerad effekt er- hålles hos såväl gasturbindelen som ångturbindelen.A further advantage is that sulfur in the fuel can react "dry" with a suitably selected bed material, eg dolomite, and thereby is absorbed by it to form gypsum and is removed together with ash from the fuel and spent bed material. Dispersion of sulfur compounds with the flue gases. can thus be prevented 10 15 20 25 35 soo? 21a ~ s 4 A particularly great advantage is that coal can be burned completely at so. low temperature as 800 = 850 ° C., that the temperature in the fluidized bed must be kept within tight. limits involve certain problems which, however, can be eliminated by the invention, Fig; 5 illustrates this. The temperature of the bed 3 should be kept within the interval A43. Within the interval B-C, combustion can be maintained but reduces the absorption of sulfur and turbine power and decreases the degree of heating. above level A, ash melts, which can form lumps that clog air and fuel nozzles or that can form droplets that accompany the combustion gases and settle in the cleaner and on. hmbinskovlæ. Because the ambient temperature drops below the so-called lay-out temperature '29 and the density of the air and thus the mass flow through the compressors increases, 25% the oxygen that is available for combustion. This. Oxygen can only be used to a very small extent for the combustion of an increased amount of fuel, unless cooling of the bed can be increased. The cycle effect of the anxiety loop is largely constant and increased combustion causes the temperature of the bed to rise rapidly to an impermissible level. The excess air factor rises as illustrated in row 4. The excess air factor Ä has been deposited on the vertical axis and the external air point T. To = + 50 ° C. At the laying temperature ratio Ä = 1.5. at Ä below 1.5, the atmosphere in the bed becomes reducing and corrosion is obtained. tubes in the bed. Å = 1.5 is thus it. lowest. excess air vector that can be allowed. Without increased cooling, the supply of fuel cannot be increased in proportion to the amount of oxygen available at temperatures below To. The value of Ä rises as the sloping solid line A63 shows. Reduced power is obtained with both the gas turbine part and the steam turbine part.
Pig 5 visar kraftarläggningens utlevererade effekt, dvs den effekt som avges av ångtuzrbinen 21 och gaeturbindelens kraftturbin 13. Ãngburbinen 21 avger en i allt väsentligt konstant effekt mellan -3000 och +30°C. Därefter sjunker effek» ten med stigande omgivningstemperatur. Se kurvan ABC. Kraftgastxzrbinen 15 avger en effekt som är differensen mellan kurvorna. DEF och ABC i det fall uppfinningen ej tillämpas vid drift av anläggningen. När omgivningstemperatxxren sjunker under ueleggingsfemperemen so -_~ +3o°c stiger effekten något genom det sme luft- mzssflödet. över TO Junker effekten på. gnmd av att minskad syremängd står till förfogande för förbränningen och bränsletillförseln måste minska för att Å ej skall junks. under tillåtet värde. I det fall uppfinningen tillämpas vid drift av snläggaingen avger ln-sfthirbinen en effekt som är differensen mellan kwxrvorna GEF ooh ABC. 'Iillskottseffektexn som kan erhålles genom tillämpning av uppfin- ningen är skillnaden mellan kæirvdelame GE och DE.

Thereafter, the effect decreases with increasing ambient temperature. See curve ABC. The power gas turbine 15 emits an effect which is the difference between the curves. DEF and ABC in case the invention is not applied in the operation of the plant. When the ambient temperature drops below the ambient temperature so -_ ~ ~ + 30 ° C, the effect rises slightly through the small air flow. over TO Junker effect on. Due to the fact that a reduced amount of oxygen is available for combustion and the fuel supply must be reduced so that Å does not junk. below the permissible value. In the case where the invention is applied in the operation of the coil, the ln-sfthirbine emits an effect which is the difference between the quarks GEF and ABC. The additional effect that can be obtained by applying the invention is the difference between the parts GE and DE. This additional effect is achieved
