Doterajší stav technikyBACKGROUND OF THE INVENTION
Na dosiahnutie vyšších vstupných teplôt horúcehoTo achieve higher hot inlet temperatures
P1 ynu privádzaného do plynovej turbíny sa tento horúci plyn priamo dodatočne ohrieva v prídavnom kúrenisku čiastkovým prúdom spalín, ktorý sa odvádza z kúreniska s fluidnou vrstvou a čistí (DE-OS 36 13In the gas turbine, this hot gas is directly additionally heated in a supplementary furnace with a partial flow of flue gas which is discharged from the fluidized bed furnace and cleaned (DE-OS 36 13).
300). Tento spôsob prevádzky má síce výhodu v tom, že prevádzka kúreniska s fluidnou vrstvou a prídavného kúren i ska je zaručený iba jedným palivom, avšak jeho nevýhodou je, že v kúrenisku s cirkulačnou fluidnou vrstvou existujú vyššie náklady na zariadenie a na získavanie horľavého čiže vykurovacieho plynu na dodatočný ohrev sa vykonáva v potrubiu na palivo a po po 1 a v oblasti pr í vodu pa1 i va .300). This mode of operation has the advantage that the operation of the fluidized bed furnace and the additional furnace and the ska is guaranteed by only one fuel, but the disadvantage is that in the fluidized bed furnace there are higher equipment costs and for obtaining a combustible or fuel gas. for additional heating, it is carried out in the fuel line and after 1 and in the water supply zone.
Riadenie potrebného spaľovacieho vzduchu nie ďalších opatrení, takže je dosiahnuté iba využitia vykurovacieho plynu z čiastkového prúdu spalín.Control of the necessary combustion air, not further measures, so that only the use of fuel gas from the partial flue gas stream is achieved.
Ďalej je známe odoberanie tohoto čiastkového prúdu spalín v podstechiometricky prevádzkovanej oblasti kúreniska s fluidnou vrstvou pred prívodom sekundárneho vzduchu (EP 03 40 351). Na spaľovanie v zariadení na dodatočné spaľovanie sa k tomu potrebný čistý vzduch vedie prívodnými potrubiami vzduchu, kúreniskom s fluidnou vrstvou a čistiacimi, ako aj deliacimi zariadeniami. Tým sú tieto zariadenia zaťažené značnými objemovými prúdeniami a čistý vzduch je obohatený jemnými pevnými čiastôčkami, takže nie je možné dosiahnuť požadované výhody.Further, it is known to remove this partial flue gas stream in a substantially stoichiometric operation of the fluidized bed furnace prior to the supply of secondary air (EP 03 40 351). For combustion in the afterburning plant, the clean air required for this is led through the air supply ducts, the fluidized bed furnace and the cleaning and separating devices. As a result, these devices are loaded with considerable volumetric flows and clean air is enriched with fine solid particles, so that the desired benefits cannot be achieved.
Pre kombinovanú elektráreň s vyvíjačom, pary vykurovaným uhlím je známe tento vyvíjač pary s podstechiometricky prevádzkovaným kúreniskom s fluidnou vrstvou opatriť ďalej zaradeným integrovaným odlučovačom prachu a kotlom s taviacou komorou opatreným horákmi (DE-OS 36 44 030). Tento vyvíjač pary však má nevýhodu v tom, že iba hrubo vyčistené spaliny so všetkými škodlivými látkami (napríklad alkáliami) sa síce v taviacej komore zbavuje popola, avšak škodlivé látky sa stanú úplne prchavými. Tieto škodlivé látky spôsobujú poškodenie plynovej turbíny. Navyše je aj tu celý prúd spalín a čistého plynu vedený všetkými zariadeniami.For a combined power plant with a coal-fired steam generator, it is known to provide the fluidized-bed furnace with a substoichiometric operation of a fluidized bed furnace with an integrated dust separator and a boiler with a melting chamber equipped with burners (DE-OS 36 44 030). However, this steam generator has the disadvantage that only roughly cleaned flue gas with all harmful substances (e.g. alkali) is free of ash in the melting chamber, but the harmful substances become completely volatile. These harmful substances cause damage to the gas turbine. In addition, the entire flue gas and clean gas flow is conducted through all the devices.
Pre kombinovaný proces s plynovými a parnými turbínami je známe spracovanie 80 % paliva čiastkovým splynovaním v splynovači a 20 % paliva ako zvyšky po splyňovaní spaľovať v kotli s kúreniskom s fluidnou vrstvou (DE-OS 36 12 888). Táto technológia nevyžaduje iba nákladnú techniku zariadenia, lež navyše vedie ešte k znečisteniu odpadného plynu z turbín spaľovaním zvyškov zo spaľovania. a preto vyžaduje ešte zvláštne čistenie spalín, zaradenej za kotlom.For a combined process with gas and steam turbines, it is known to treat 80% of the fuel by partial gasification in a gasifier and 20% of the fuel as gasification residues in a fluidized bed boiler (DE-OS 36 12 888). This technology not only requires expensive equipment technology, but also leads to contamination of the off-gas from turbines by combustion of the combustion residues. and therefore requires a special cleaning of the flue gas downstream of the boiler.
Úlohou vynálezu je pomocou jednoduchého zariadenia a technológie získať a využiť vykurovací čiže horľavý plyn s vysokými kalorickými hodnotám i to znamená dosiahnuť optimálneho dodatočného spálenia spalín pre maximálnu vstupnú teplotu do plynovej turbíny.SUMMARY OF THE INVENTION The object of the invention is to obtain and utilize, with the help of a simple device and technology, a heating or combustible gas with high calorific values.

The steam boiler 7 is provided with a flue gas duct 6 which flows into the flue gas cleaning device 7 in the form of a cyclone. An outlet pipe 8 leads therefrom to an afterburner 9 which is provided with a clean air inlet 10. The afterburner 9 is a hot gas line 11 connected to a gas turbine 12 provided with a waste gas line 13. A compressor 14 is connected to the gas turbine 12, which is provided with a fresh air inlet and an outlet 16. The outlet 16 is connected to a combustion air supply line 17 with a combustion air supply 5 and a clean air supply line 18 to a clean air supply 10. Pipes 17 and 18 are provided with control devices 19, 20 which are provided with drives 21, 22. Drives
21, 22 sú vedeniami 23, 24 spojené s riadiacim zariadením 25, ktoré je riadiacim vedením 26 spojené s meracím zariadením 40 na meranie kvality paliva. Odvádzacie potrubie 27 popola zo zariadenia 7 na čistenie spalín ústi do kúreniska 3 s fluidnou vrstvou a je opatrené odtahom 28 popola.21, 22 are connected via lines 23, 24 to a control device 25, which is connected to the control device 26 with a fuel quality measuring device 40. The ash discharge pipe 27 from the flue gas cleaning device 7 flows into the fluidized bed furnace 3 and is provided with an ash withdrawal 28.
Spôsob činnosti je nasledujúci:The method of operation is as follows:
Prívodom 2 paliva fluidnou vrstvou privádza závislosti na kvalite pal sa do kúreniska 3 s cirkulačnou palivo 30, napríklad hnedé uhlie.The fluidized bed fuel supply 2 supplies fuel-fired furnaces 30, for example brown coal, depending on the quality of the fuel.
prúd 31 čistého vzduchu medzi dodatočné spaľovanie pomocou regulačných zariadení 1_9,a clean air flow 31 between the afterburner by means of the control devices 19,
Privedením signálu oApplying a signal o
'kva 1 i te pa 1 i va sa na do r i adi aceho zariadenia 25 sa prúd 31 čistého vzduchu delí v pomere 1In the control device 25, the clean air stream 31 is divided in a ratio of 1
1, takže príslušný podiel množstva čiastkového prúdu 33 spaľovacieho vzduchu sa vedie do kotla 1 č i astkového prúdu 34 čistého vzduchu do zariadenia 9 na dodatočné spaľovanie. V kotli 1^ sa preto vytvárajú spaliny bohaté na CO tým, že kúrenisko 3 fluidnou vrstvou pracuje so vzduchovým pomerom1, so that an appropriate fraction of the amount of combustion air sub-stream 33 is fed to boiler 1 or clean air sub-stream 34 to post-combustion apparatus 9. Therefore, CO-rich flue gas is produced in the boiler 1 by operating the furnace 3 with the fluidized bed at an air ratio.

Spaliny 35 sa vedú do zariadenia 7 na čistenie spalín. Tu sa vylučuje suchý popol 36 s ešte obsiahnutými škodlivými látkami. Na zachovanie rovnováhy množstva sa čiastkový prúd 37 popola vedie do kúreniska 3 s fluidnou vrstvou a čiastkový prúd 29 popola sa odvádza odťahom 28 popola. Výstupným potrubím 8 sa vyčistené spaliny 38 privádzajú do zariadenia 9 na dodatočné spaľovanie. V zariadení 9 na dodatočné spaľovanie sa vyčistené spaliny 38 bohaté na CO pomocou čiastkového prúdu 34 čistého vzduchu dodatočne spaľujú a tým vzniká horúci plyn 39. Tento horúci plyn 39 sa vedie do plynovej turbíny 1 2. Odpadný plyn sa vedie potrubím 13 na odpadný plyn napríklad do kotla na odpadné teplo. Plynová turbína 12 poháňa generátor a kompresor 14, takže prívodným potrubím 15 čerstvého vzduchu sa na výstupe 16 pripravuje potrebný prúd 31_ čistého vzduchu.The flue gas 35 is fed to a flue gas cleaning device 7. Here, dry ash 36 with the harmful substances still contained is eliminated. In order to maintain the equilibrium of the quantity, the partial ash stream 37 is fed to the fluidized bed furnace 3 and the partial ash stream 29 is discharged by drawing ash 28. Through the outlet pipe 8, the cleaned flue gas 38 is fed to the afterburner 9. In the post-combustion plant 9, the cleaned CO-rich flue gas 38 is recycled through the clean air sub-stream 34, thereby producing hot gas 39. This hot gas 39 is fed to a gas turbine 12. to the waste heat boiler. The gas turbine 12 drives the generator and the compressor 14, so that the fresh air supply line 15 prepares the necessary clean air stream 31 at the outlet 16.
Podstechiometrickou prevádzkou sa dosiahne podstatný nárast množstva paliva, čím je dosiahnutý vyšší výkon kotla 1 na výrobu pary. Súčasne sa s rozdelením spaľovacieho procesu dosiahne vyššia teplotná úroveň horúceho plynu a pomocou s tým spojeného vyššieho stupňa účinnosti plynovej turbíny je umožnené zvýšenie výkonu celého zariadenia. Okrem toho sa vyššou účinnosťou emituje menej COz , čím je menej zaťažované okolité prostredie.Substoichiometric operation results in a substantial increase in the amount of fuel, thereby achieving a higher output of the steam boiler 1. At the same time, a higher temperature level of the hot gas is achieved with the distribution of the combustion process, and the associated higher degree of efficiency of the gas turbine makes it possible to increase the performance of the entire plant. In addition, less CO 2 is emitted by higher efficiency, thus less burdening the environment.

Výhody vynálezu vznikajú aj v kúrenisku s cirkulačnou fluidnou vrstvou s prívodom primárneho, sekundárneho a terciárneho vzduchu, keď je čiastkové potrubie horľavého plynu odberovým i m í estam i zaústené do podstech i ometr i cky prevádzkovanej časti kúren i ska s fluidnou vrstvou pred prívodom sekundárneho vzduchu. Čiastkové potrubie horľavého plynu vedie cez zariadenie na čistenie horľavého plynu do zariadenia na dodatočné spaľovanie opatreného prívodom čistého plynu. Takto získaným vysokoka1 or ickým horľavým plynom, ktorý neobsahuje prachové čiastôčky, v zariadení na dodatočné spaľovanie vyrábajú spaliny z kúreniska s fluidnou vrstvou horúci plyn s teplotami nad :l 100 “C.The advantages of the invention also arise in a circulating fluidized bed furnace with a primary, secondary and tertiary air supply, where the combustible gas sub-duct is connected to the fluidized bed part of the furnace and the fluidized bed prior to the secondary air supply. The combustible gas sub-conduit leads through the combustible gas scrubber to a post-combustion plant equipped with a clean gas supply. The thus obtained high-grade, non-particulate combustible gas in a post-combustion plant produces hot gas from a fluidized bed furnace with temperatures above: 1100 ° C.
