DESCRIPTION USING A MULTI-DRUM SCHEDULE FACE THICKNESS REDUCED LIVIIS DRUM STEAM BOILER SUBJECT OF THE INVENTION The present invention is used, for example, in the power plants or process industries sector and drums subject to frequent and fast starts with high operating pressures relates to the field of boilers.
Mevcut bulus bilhassa isi geri kazanimli buhar kazani ya da HRSG (hear recovery steam generator) tipi kazanlara iliskindir. The present invention is particularly suitable for a heat recovery steam boiler or HRSG (hear recovery steam boiler). pertains to generator) type boilers.
TEKNOLOJIK ARKA-PLAN VE TEKNIGIN BILINEN DURUMU Eneji pazarinin gelisimi günümüzde üretim birimlerinde daha büyük esneklik ihtiyaci dogurmustur zira kazan tamburlarinin kalinliklari döngüsel yorgunluk bakimindan giderek artan siklikta sorun haline gelecegi sekilde yeterince yüksek çalisma basinçlari vardir. TECHNOLOGICAL BACKGROUND AND KNOWN STATE OF ART The evolution of the energy market requires greater flexibility in production units today. because the thickness of the boiler drums is gradually increasing in terms of cyclic fatigue. there are sufficiently high working pressures that they become a problem with increasing frequency.
Bu yüzden kazan tamburlarinin, bilhassa kritik kosullarda, yorgunluga karsi dirençli olabilmeleri için, tamburlarin optimum sekilde boyutlandirilmasi istenir, bu kritik kosullar sunlardir: sartnamede kazanin birçok baslangiç yapmasinin öngörülmesi ve bunlarin basinç yükselis gradyanlarinin yüksek olmasi; asagidaki iki sebep yüzünden kalin çeperli tamburlar tasarlanmis olmasi: ° yüksek çalisma basinçlari yüksek tasarim basinçlarini gerektirir; ° geçislerin veya istisnai çalismalarin zorunlu kildigi daha büyük depolama hacimlerine olan talebi karsilamak için büyük çaplara basvurulur. That's why boiler drums are fatigue-resistant, especially under critical conditions. Optimum sizing of the drums is required so that they can be are: In the specification it is foreseen that the boiler makes many starts and their pressure high elevation gradients; Thick-walled drums are designed for the following two reasons: ° high operating pressures require high design pressures; ° larger storage mandated by transitions or exceptional work Large diameters are used to meet the demand for volumes.
Yüksek basinçli tamburlarin (HP) yorgunluk sorunlarinin etkili biçimde azaltilmasini saglayan bilinen üç tip çözüm vardi: zorlamali dolasimli kazan (veya “once through”): HP kazanin tamburu yerine, çapi tamburunkinden daha küçük olan bir ayirici kullanilir. Bunun avantaji yorulmaya karsi direncin daha yüksek olmasidir çünkü ilgili kalinliklar daha zayiltir. Bu alternatif teknoloji daha karmasik bir kazan borusu donanimini gerektirir ve ayrica çok yüksek saflikta bir su kalitesinin kullanilmasina yol açar. Bununla birlikte daha düsük hatta sifir olan bir depolama kapasitesi belirli istisnai çalismalari daha kritik hale getirir; çok tamburlu kazan: kazanin içinde dikkate alinan bir basinç seviyesi için tek bir tamburu dikkate almak yerine, tamburun depolama hacmi toplam kapasitesi esit olan iki hazneye dagitilmistir. Iki haznenin çaplari tek bir tamburun çapina göre belirgin bir seklide daha küçüktür, bu da ilgili kalinliklari da azaltmayi ve böylece esas itibariyle yorulma sorununu iyilestirmeyi saglar. Teknigin bilinen durumunda önerilen çözüm Piyasaya sürülen bir baska örnekte, nihai sur/buhar ayirma adimini tamburun disinda gerçeklestirmek için tamburun disina ayiricilar yerlestirilmesinden ibaret bir çözüm önerilmistir, bu da normal çalisma seviyesinin ve ana tamburun yüksek seviyeden baslatilma seviyesinin yükselebilmesine yol açar. Bu durum ana tamburun çapinin ve kalinliginin azalmasini saglar; yöntemin kontrolüne bagli çözümler: ° üretilen buhar için çikislar (buhar delikleri, buhar türbininin bypass valfi, vb.) uygun biçimde kullanilarak, tertibat baslatilirken öncelikli olarak basinç yükselmesi gradyanlarini sinirlandirmak için bir yöntem. Bu çikislar tamburun içindeki basinç/ sicaklik yükselmesini kontrol eden bir mantiga bagimlidir. Bu çözümün en büyük kusuru kazanin içinde nominal basincin kurulmasini geciktirmesidir (yania baslangiç daha yavas olur) bu da günümüzde pazar ihtiyaçlarina giderek daha az uyumludur; ° bir baska yöntem, yorgunluk bakimindan en zorlayicilari olan soguk baslangiçlari engellemek amaciyla, bir sonraki baslangiç ihtimali göz önünde tutularak, bir duraklamadan sonra kazani az çok “sicak" ve dolayisiyla az çok basinçli tutmaktir. Effectively reducing the fatigue problems of high pressure drums (HP) There were three known types of solutions that provided: forced circulation boiler (or “once through”): instead of the drum of the HP boiler, the diameter a separator smaller than that of the drum is used. The advantage of this is against fatigue. This is because the resistance is higher because the respective thicknesses are weaker. This alternative technology requires a more complex boiler tube hardware and also very high leads to the use of a pure water quality. However, even lower a storage capacity that makes certain exceptional work more critical; multi-drum boiler: a single boiler for a considered pressure level inside the boiler instead of taking into account the drum, the storage volume of the drum is equal to its total capacity. distributed in two chambers. The diameters of the two chambers differ significantly from the diameter of a single drum. is smaller, which also reduces the thicknesses involved and thus substantially It helps to improve the fatigue problem. Suggested solution in the state of the art In another example on the market, the final water/steam separation step is outside the drum. A solution consisting of placing separators outside the drum to achieve recommended, which means that the normal operating level and the main drum are higher than the high level. causes the start-up level to increase. In this case, the diameter of the main drum and it reduces the thickness; Solutions based on method control: ° outlets for the steam produced (steam vents, bypass valve of the steam turbine, etc.) are suitable pressure rise as a priority when starting the device. A method for constraining gradients. These outputs are pressure/pressure inside the drum. it depends on a logic that controls the temperature rise. This solution is the biggest its defect is that it delays the establishment of the nominal pressure inside the boiler (i.e. starting slower) which is less and less in line with market needs today; ° another method is cold starts, which are the most challenging in terms of fatigue. in order to prevent it, taking into account the possibility of the next start, a after the pause is to keep the boiler more or less “hot” and therefore more or less pressurized.
Bu sicak/basinçli tutma ana kazanin içine yardimci buhar püskürtmesi sayesinde mümkün kilinir. Bu yöntemin dezavantajlari, yakinlarda kullanilabilir bir yardimci buhar kaynaginin bulunmasi ve ayrica bu buhar tüketimine bagli enerji tüketiminin desteklenmesi gerekliligidir; ° Ievhalarin dogrudan isitilmasiyla (trace heati'ng) tamburun çeperlerinin sicak tutulmasi gibi baska imkânlar da mevcuttur. This heat/pressure retention is due to auxiliary steam injection into the main boiler. is possible. The disadvantages of this method are that there is no nearby available helper. the presence of the steam source and also the energy consumption due to this steam consumption. the need for support; ° With direct heating of the sheets (trace heati'ng), the drum walls There are also other possibilities, such as keeping
Sunumun devami için asagida iki önemli kavram tanimlanmistir: ROT: "run-out time" ve akis süresi sartnamede anlasmali olarak tanimlanan bir süredir, bunun tekabül ettigi süre, tamburun besleme pompalari üzerinden suyla beslenmeksizin çalisabilmesi gerektigi süredir; doldurulur. Bu su isinip kaynama noktasina ulastiginda, büyük bir su hacmi tambura dogru itilir ve buharlastiricinin borulari içinde bu suyun yerini buhar alir. Tambur kizdiricilara dogru tasmamayi garantileyerek, bu su hacmini içine alabilecek sekilde boyutlandirilmalidir. Bu olay belirli yük geçisleri sirasinda da meydana gelebilir. For the continuation of the presentation, two important concepts are defined below: ROT: "run-out time" and flow time is a period defined by agreement in the specification, the corresponding time is watered through the feed pumps of the drum. the time it needs to be able to work without feeding; is filled. When this water heats up and reaches its boiling point, a large volume of water enters the drum. it is pushed towards and this water is replaced by steam in the pipes of the evaporator. drum be able to contain this volume of water, ensuring no overflow to the superheaters should be sized. This event can also occur during certain load transitions.

BULUSUN TERCIH EDILEN BIR GERÇEKLESTIRME SEKLiNiN TANIMl Mevcut bulus çerçevesinde Önerilen çözüm çok tamburlu çözümlerin bir parçasidir. DEFINITION OF A PREFERRED MANAGEMENT OF THE INVENTION In the framework of the present invention, the proposed solution is part of multi-drum solutions.
Buradaki prensip. hem zorunlu kilinan akis zamanini (ROT) saglamak için hem de baslangiç sirasinda veya yük geçisleri sirasinda sisme hacmini (sweli' effect) içine almak için gerekli olan depolama hacmini en az iki hazneye veya temel tikrin genellestirilmis bir versiyonunda ikiden fazla hazneye dagitmaktir. The principle here. both to provide the required time-of-flow (ROT) and encompass the sweli' effect during startup or load transitions the required storage volume for at least two chambers or a generalized distribution of the basic type. version is to distribute to more than two chambers.
Sekil 2'de gösterilen bulusa uygun olarak önerilen iyilestirmeyi kapsayan yeni tertipte, iki hacim ayirt edilmelidir: depolama haznesi 8 ve su/ buhar ayrimini gerçeklestiren kazan tamburunun kendisi 1. Depolama haznesi veya depolama tamburu 8 kontrol valfi 5 denilen birinci bir valf “A" içeren besleme suyu borusundan 4 su ile beslenir. Bu depolama haznesi 8 normal çalisma sirasinda tamamen doludur ve tasma borusu 9 üzerinden kazan tamburunu 1 besler. Normal çalismada, tamburun acil besleme borusunu 11 (backup drum feedi'ng !ine - BFL) donatan etkinlestirilebilen vali 10 denilen ikinci bir valf “B” kapalidir. In the new scheme, which includes the proposed improvement in accordance with the invention shown in Figure 2, two the volume must be distinguished: the storage chamber 8 and the boiler with water/steam separation drum itself 1. Storage chamber or storage drum 8 so-called control valve 5 It is fed with water from the feed water pipe 4, which includes a first valve “A”. This is the storage chamber 8 is completely full during normal operation and the overflow pipe 9 feeds the drum 1. In normal operation, connect the drum's emergency feed pipe 11 (backup drum A second valve “B”, called the activable governor 10, which equips the feedi'ng !ine - BFL), is closed.
Kazan tambur 1 "inis borulari - buharlastirici - yükseltme borulari" döngüsüne baglidir: su tamburdan 1 buharlastiriciya 2 dogru su inis borularindan 6 akar, bu durumda su, buharlastiricinin 2 borularinin içinden geçer ve bu borularin içinde kismen buharlasir, sonra bu su/buhar karisimi yükseltme borulari 7 üzerinden tambura 1 dogru gönderilir. Su/buhar fazi olan iki faz tamburun 1 içinde, meslek erbabi tarafindan kendinden bilinen uygun bir veya birçok donanimla (yöntemle) ayrilir. Boiler drum 1 is connected to the "downpipes - evaporator - rise pipes" cycle: water flows from drum 1 to evaporator 2 through downpipes 6, in this case water, passes through the pipes of the evaporator 2 and partially evaporates inside these pipes, then this water/steam mixture is sent to the drum 1 via the riser pipes 7. water/steam in a two-phase drum 1 with a suitable or separated by many hardware (methods).
Tamburun 1 içindeki suyun düzlem seviyesi kontrol valti “A" 5 tarafindan kontrol edilir. The level of the water in the drum 1 is controlled by the control valve “A” 5.
Tamburun 1 su düzleminin üstündeki doymus buhar, bu amaçla öngörülmüs bir tabandan 3 tamburun disina çikar ve (gerekirse) kizdiricilar üzerinden buhar sebekesine dogru yönlendirilir ve böylece sonra, üretilen buhari kullanan buhar prosesini veya türbinini besler. istisnai çalismada, ayirma tamburunun 1 seviyesi seçilmis bir kritik esigin altina düsünce veya besleme pompalari harekete geçirince, etkinlestirilebilen “B” valfi 10 kismen ya da tamamen açilir: böylece tasma borusu 9 hava deligi islevini görür ve BFL 11 tamburu 1 besler. Böylelikle, birlesik kaplar ilkesiyle, depolama haznesinin hacmi gerekli BOT'u saglamak üzere katki saglar. Bununla birlikte, tasma borusu 9 ayirma tamburunun 1 içinde yeterince alçak bir konuma açilmalidir, böylece tamburun üst kisminda, kizdiricinin veya buhar dolasim borularinin içine tasacak sekildeki asiri su yükselmeleri engellenir. Saturated steam above the water plane of the drum 1 is discharged from a floor 3 intended for this purpose. out of the drum and (if necessary) through the superheaters to the steam mains is directed and thus then feeds the steam process or turbine that uses the generated steam. In exceptional operation, level 1 of the separation drum falls below a selected critical threshold. or when the feed pumps actuate, the activable valve “B” 10 partially or fully opens: so that the overflow tube 9 acts as the vent and the BFL 11 drum 1 feeds. Thus, on the principle of unified containers, the volume of the storage chamber provides the required BOT. contributes to provide. However, the leash 9 is inside the separation drum 1 it must be opened to a low enough position so that the upper part of the drum, the superheater or Excessive water rises to overflow into the steam circulation pipes are prevented.
Dahasi, baslangiçta, yeni gerçeklestirme tarzina uygun olarak, etkinlestirilebilen “B” valfi 10 açik konumda tutulabilir. Böylece sisme etkisi meydana geldiginde mukabil su fazlasi eskiden oldugu gibi tek hazne yerine, kazan tamburu 1 ve depolama haznesi 8 olmak üzere iki haznenin içine alinir, bunlar birlikte, birlesik kaplar ilkesi sayesinde, saglanan toplam su hacmini çekmeye katki saglarlar. Moreover, initially, in accordance with the new mode of execution, the activable “B” valve 10 can be kept in the open position. Thus, when the swelling effect occurs, the corresponding excess water to be boiler drum 1 and storage chamber 8 instead of a single chamber as before taken into two chambers, these together, thanks to the principle of unified containers, provided they contribute to attracting the total water volume.
Bulus prensibine göre asagidaki alternatifler ve genellemeler yapilabilir: - önerilen iyilestirme prensibi dikkate alinan kazan -düsey veya yatay veya karma HBSG- tipinden bagimsizdir; - temel fikir kapsaminda, kazan tamburunun yan taraflarinda tek bir depolama haznesi dikkate alinmistir. Ancak, depolama haznelerinin çaplarini daha fazla küçültmek ve dolaysiyla tamburlarin/haznelerin kalinliklarini daha da fazla küçültmek için (ki bunlar gerekirse bir boru tesisati bütünü olabilir), bu fikrin depolama haznesi sayisinin ihtiyaca göre arttirilarak genellestirilmesi karsisinda hiçbir engel yoktur; - BFL`nin tambura bagli olmak yerine dogrudan inis borusunun içine bagli olmasi dikkate alinabilir; - önerilen iyilestirme prensibi su/ buhar fazlarinin ayrilmasini ve buharin kurutulmasini gerçeklestirmek için kullanilan yöntemlerden ve donanimlardan bagimsizdir; - önerilen iyilestirme prensibi sistemin su ile beslenmesinin ve hava deliginin gerçek geometrisinden bagimsizdir, esas olan tamburun ve depolama haznesinin (haznelerinin) gerektiginde birlesik kaplar olarak çalisabilmelerini saglamaktir; - önerilen iyilestirme prensibi FWCV “A`”nin 5 konumundan bagimsizdir, yani kazandaki ekonomizörler akis yönünde önce veya sonradir; - önerilen iyilestirme prensibi “A” ve “B" valflerini düzenlemek için olan elemanin tipinden bagimsizdir. According to the invention principle, the following alternatives and generalizations can be made: - boiler taking into account the proposed improvement principle - vertical or horizontal or mixed Independent of HBSG- type; - as part of the basic idea, a single storage chamber on the sides of the boiler drum has been taken into account. However, to further reduce the diameter of the storage chambers and therefore to further reduce the thickness of the drums/hoppers (which if necessary, it can be a piping assembly), the idea that the number of storage chambers depends on the need. There is no obstacle to generalization by increasing according to - Note that the BFL is connected directly to the downpipe instead of to the drum. receivable; - the proposed curing principle is the separation of the water/steam phases and the drying of the steam independent of the methods and hardware used to perform it; - the proposed remediation principle is the actual water supply of the system and the vent. is independent of its geometry, the main thing is that the drum and the storage chamber to ensure that (reservoirs) can function as composite vessels when necessary; - the proposed healing principle is independent of the 5 positions of the FWCV “A”, ie in the boiler economizers upstream or downstream; - from the type of element for regulating the proposed improvement principle “A” and “B” valves is independent.
Mevcut bulus çerçevesi kapsaminda önerilen çözüm daha önce açiklanan ve gerektiginde bilhassa asagidaki noktalari itibariyle teknigin bilinen durumunda korunan çözümlerden ayrilir. Mevcut bulusa göre: A. inis borulari su/ buhar ayrimini gerçeklestiren tambura baglidir; B. temel iyilestirme prensibinin islemesi için iki tamburun farkli yüksekliklerde olmasi gerekmez (ama olabilirler de), bu da çevreleyen yapi kafesinin tasarimini basitlestirir; C. su/ buhar ayrimini gerçeklestiren tamburun beslenmesi depolama tamburunun tasmasiyla gerçeklesir. Bu sebeple, normal çalismada depolama tamburu tamamen su ile dolar, bu da onun faydali hacmini azami seviyeye çikarir.The solution proposed under the current framework of invention has been described previously and, where necessary, one of the solutions protected in the state of the art especially with respect to the following points are separated. According to the present invention: A. the downpipes are connected to the drum that realizes the water/steam separation; B. two drums at different heights for the basic improvement principle to work not required (but they can be), which simplifies the design of the surrounding structural cage; C. feeding the drum that realizes the water/steam separation is the storage drum takes place with the collar. Therefore, in normal operation, the storage drum is completely filled with water. filled with, which maximizes its useful volume.
