Pakokaasulta tti laFrom the exhaust gas tti la
Energian kallistumisen myötä on yhä suuremmassa määrin alettu kiinnittää huomiota pakokaasujen energia-5 sisältöön ja sen hyödyntämiseen. Tämän vuoksi on kehi tetty eri tyyppisiä pakokaasukattiloita. Kattilat on suunniteltu joko luonnolliselle vedenkierrolle tai pakko-kierrolle. Nykyään on suurimmassa osassa laivoja käytössä pakokaasukattilalaitokset, jotka turvaavat poistuvien 10 kaasujen lämmön hyväksikäytön.As energy prices have risen, more and more attention has been paid to the energy-5 content of exhaust gases and its utilization. For this reason, different types of exhaust gas boilers have been developed. The boilers are designed for either natural water circulation or forced circulation. Today, most ships have exhaust gas boiler plants in place that ensure the heat recovery of the 10 exhaust gases.
Käytössä olevat pakokaasukattilat ovat joko tuli-putki- tai vesiputkirakenteisia. Vesiputkirakenteiset kattilat ovat paremman lämpöpinta/painosuhteensa vuoksi yleistyneet. Vesiputkirakenteisia pakokaasukattiloita 15 on käytössä sekä sileäputkisia että lämmönsiirtoa tehostavilla rivoilla varustettuja ripaputkikattiloita.Exhaust boilers in use are either fire-pipe or water-pipe. Water-tube boilers have become more common due to their better heating surface area / weight ratio. Exhaust gas boilers 15 with water-tube structure are used, both smooth-tube and finned tube boilers with fins that enhance heat transfer.
Pakokaasukattilat ovat ulkomuodoltaan joko suorakaiteen muotoisia tai sylinterimäisiä. Sileäputkiset pakokaasukattilat ovat yleensä sylinterin muotoisia, 20 koska vesiputket on helppo valmistaa kierukan muotoisiksi. Keksinnön mukainen kattila on edullisesti tämän tyyppinen.Exhaust boilers are either rectangular or cylindrical in appearance. Smooth-tube exhaust boilers are generally cylindrical in shape because water pipes are easy to make helical. The boiler according to the invention is preferably of this type.
Pakokaasukattilan säätö on usein tuonut ongelmia, koska esim. laivalla lämpöenergian tarve vaihtelee melkoisesti. Lisäksi vaihtelee myös pakokaasujen määrä moot-25 torin kuormituksen mukaisesti. Jotta laivaolosuhteissa on päästy riittävään toimintavarmuuteen, on nykyisin käytössä olevissa ratkaisuissa tingitty säätöominaisuuksista. Pakokaasukattiloiden säätö nykyisissä laivoissa tapahtuu yleensä jollain seuraavista tavoista: 30 - Kattila jaetaan blokkeihin, joista osa voidaan pitää kuivana, kun halutaan pienentää kattilan tehoa. Menetelmän heikkoutena on se, että säätö on portaittainen ja lämpölaajeneminen aiheuttaa rasituksia kattilaan.The adjustment of the exhaust boiler has often brought problems, because, for example, the need for thermal energy on board varies considerably. In addition, the amount of exhaust gases also varies according to the load on the engine. In order to achieve sufficient reliability in ship conditions, the control features have been compromised in the solutions currently in use. Exhaust boilers in existing ships are usually adjusted in one of the following ways: 30 - The boiler is divided into blocks, some of which can be kept dry when it is desired to reduce the power of the boiler. The weakness of the method is that the control is stepwise and the thermal expansion causes stresses on the boiler.
Toisena vaihtoehtoisena säätötapana käytetään 35 ylimääräisen tehon ajamista lämmönsiirtimien välityksellä mereen. Menetelmä on varmatoiminen, mutta kallis, koska 2 64978 tällöin tarvitaan ylimääräistä lämmönvaihdinkapasiteettia.Another alternative control method is to drive 35 extra power through heat exchangers to the sea. The method is reliable but expensive because 2,64978 requires additional heat exchanger capacity.
- Kolmantena säätötapana käytetään pakokaasujen ohitusta. Toisin sanoen pakokaasukattilaan ajetaan vain osa pakokaasuista ja täten säädetään tehoa tarpeen mukaan.- Exhaust gas bypass is used as the third control method. In other words, only a part of the exhaust gases is driven into the exhaust boiler and thus the power is adjusted as required.
5 Pakokaasukattilan ohituskanava on yleisimmin raken nettu kattilan ulkopuolelle ja säätöpelti on tavallisesti kaksiosainen, jolloin toinen läppä säätää kattilaan menevää ja toinen ohituskanavaan menevää virtausta. Tällaisen mekanismin heikkoutena on kumminkin läpän yhtäaikainen kiin-10 nimenomahdollisuus, jolloin pakokanava on käyttökelvoton.5 The by-pass of the exhaust boiler is most often built outside the boiler and the damper is usually in two parts, with one flap regulating the flow into the boiler and the other into the bypass. The weakness of such a mechanism is the possibility of simultaneous closing of both flaps, whereby the exhaust duct is unusable.
Äänenvaimennin sijoitetaan useimmin pakokaasukattilan ja ohituskanavan jälkeiseen pakokanavaan, jolloin taataan riittävä äänenvaimennus myös pakokaasukattilaa ajettaessa. Epäkohtana tällaisessa järjestelmässä on sen kal-15 leus, suuri tilantarve ja useista osista johtuva raskas rakenne .The muffler is most often placed in the exhaust duct after the exhaust boiler and the bypass duct, which ensures adequate silencing even when driving the exhaust boiler. The disadvantages of such a system are its high cost, high space requirements and heavy structure due to several parts.
NO-patenttijulkaisussa no. 95 837 on esitetty pakokaa-sukattila, jossa pakokaasujen ohituskanava on sijoitettu kon-vektio-osan sisään toimien samalla äänenvaimentimena mutta 20 jossa pakokaasujen ohjaus on järjestetty siten, ettei äänen-vaimennusta saada, kun ohituskanava on suljettu.In NO patent publication no. 95,837 shows an exhaust boiler in which an exhaust bypass duct is located inside the convection section while acting as a silencer but 20 in which the exhaust gas control is arranged so that no sound attenuation is obtained when the bypass duct is closed.
Keksinnön kohteena on siten pakokaasukattila, joka käsittää kierukan muotoisia vesiputkia sisältävän konvektio-osan, jolloin konvektio-osa on muodostettu rengastilaksi ja 25 rengastilan ympäröimään lieriöön on muodostettu pakokaasujen ohituskanava, joka samalla toimii äänenvaimentimena.The invention thus relates to an exhaust gas boiler comprising a convection part comprising helical water pipes, the convection part being formed as a ring space and the exhaust bypass duct being formed in the cylinder surrounded by the ring space, which at the same time acts as a muffler.
Ominaista keksinnön mukaiselle pakokaasukattilalle on pääasiallisesti se, että pakokaasujen tulokanavan ja kon-vektio-osan välisen yhteyden virtausvastus on olennaisesti 30 suurempi kuin tulokanavan ja ohituskanavan välisen yhteyden virtausvastus ja että ohituskanavan poistopäähän on sovitettu säätölaite sekä konvektio-osan että ohituskanavan virtauksen säätämiseksi, niin että ohituskanava toimii äänenvaimentimena myös silloin, kun kattilan ohitus on suljettu.The exhaust gas boiler according to the invention is mainly characterized in that the flow resistance of the connection between the exhaust inlet duct and the convection section is substantially higher than the flow resistance of the connection between the inlet duct and the bypass duct. acts as a muffler even when the boiler bypass is closed.
35 Samalla keksinnön mukaisen kattilan tilantarve on pieni, esim. laitteiston vaatima korkeus on noin puolet peräkkäin olevan kattilan ja äänenvaimentimen vaatimasta tilasta.At the same time, the space requirement of the boiler according to the invention is small, e.g. the height required by the equipment is about half of the space required by the boiler and the muffler in succession.

Koska ohituskanava ja äänenvaimennin on voitu rakentaa kattilan sisälle, on saavutettu huomattava painon vähennys. Kipinänsarkijää on käytetty tukirakenteena, joka myös vähentää kokonaispainoa. Keksinnön mukaisessa kattilassa käy-5 tetään ohituskanavan säätöpeltinä yksinkertaista läppävent-tiiliä, joka on toimintavarma ja jonka säätöominaisuudet ovat hyvät.Because the bypass duct and muffler may have been built inside the boiler, a significant weight reduction has been achieved. The spark sheet has been used as a support structure that also reduces the total weight. In the boiler according to the invention, a simple butterfly valve is used as the bypass duct control damper, which is reliable and has good control properties.
Oheisessa piirustuksessa on havainnollistettu keksinnön mukainen pakokaasukattila.The accompanying drawing illustrates an exhaust gas boiler according to the invention.
10 Kuvio 1 esittää kattilaa sivulta katsottuna.Figure 1 shows a side view of the boiler.
Kuvio 2 esittää kattilaa päältä katsottuna.Figure 2 shows a top view of the boiler.
Kuvio 3 esittää kattilan halkileikkausta.Figure 3 shows a cross-section of the boiler.
Kuviossa 1 numero 1 tarkoittaa kattilan ulkovaippaa. Numeroilla 2 ja 3 on merkitty pakokaasujen sisään- ja ulos-15 tuloaukot. Kattilan jakotukit on esitetty numerolla 4 ja varoventtiili numerolla 5. Kattilan kiinnityskorvakkeet on merkitty numerolla 6 ja painemittari numerolla 7. Ohituspel-lin 12 käyttömekanismi on merkitty numerolla 8 ja kattilan päällä olevat luukut numerolla 9, joista voidaan suorittaa 20 huoltotoimenpiteet. Kattilan alakartiossa on putkiyhde numero 10, josta valuvat ulos kattilan pesuvesi ja konvektio-osasta vuotava vesi.In Figure 1, the number 1 means the outer casing of the boiler. Numbers 2 and 3 denote the inlet and outlet inlets of the exhaust gases. The boiler manifolds are shown at number 4 and the safety valve at number 5. The boiler mounting lugs are marked with number 6 and the pressure gauge with number 7. The operating mechanism of the bypass 12 is marked with number 8 and the hatches on the boiler with number 9, from which 20 maintenance operations can be performed. The lower cone of the boiler has a pipe connection number 10, from which the washing water of the boiler and the water leaking from the convection section flow out.
Kuviossa 3 näkyy kattilan konvektio-osa 21, joka sisältää kierukan muotoiset vesiputket 11. Konvektio-osa 21 on 25 rengastila, jonka ympäröimään lieriöön 22 on muodostettu pakokaasujen ohituskanava 13. Lieriö 22 on vuorattu ääntävai-mentavalla materiaalilla 16, esim. lasivillalla, jonka päällä on suojaava kalvo ja reijitetty teräslevy 14. Äänenvaimen-nuksen tehostamiseksi on lieriön 22 sisään sovitettu toinen 30 lieriö 23 ääntävaimentavine materiaaleineen 16 ja suojineen 15.Figure 3 shows a convection section 21 of a boiler containing helical water pipes 11. The convection section 21 is an annular space 25 in which an exhaust bypass passage 13 is formed in the cylinder 22. The cylinder 22 is lined with a sound-absorbing material 16, e.g. has a protective film and a perforated steel plate 14. To enhance the sound attenuation, a second cylinder 23 with sound-absorbing materials 16 and covers 15 is arranged inside the cylinder 22.
Ohituksen säätöpelti eli -läppä 12 on asennettu ohitus-kanavaäänenvaimentimen 13 yläpäähän liitettyyn putkeen 20, jolloin pellin 12 akseli on lyhyt ja laakerointi voidaan sijoittaa kattilan ulkopuolelle.The bypass damper or flap 12 is mounted on a pipe 20 connected to the upper end of the bypass duct silencer 13, whereby the shaft of the damper 12 is short and the bearing can be placed outside the boiler.
35 Äänenvaimentimen 13 alapäässä olevat siivet 17 toimi vat kipinänsärkijöinä. Siivet 17 on edullisesti asennettu sisimmän lieriön 23 tukirakenteeksi, joko suoraan tai kuvion 3 64978 mukaisesti suojaosan 15 välityksellä; viimeksimainittu on useimmissa käytännön tapauksissa kiinnitystarkoitukseen riittävän tukeva. Vaihtoehtoisesti voidaan siivet 17 kiinnittää suojaosaan 14 tai lieriöön 22. Pakokaasujen sisään-5 tulokanava 18 päättyy kipinänsärkijän 17 eteen ja on halkaisijaltaan pienempi kuin äänenvaimennin 13, niin että tulo-kanavasta 18 muodostuu yhteys 19 konvektio-osaan 21.35 The wings 17 at the lower end of the muffler 13 act as spark breakers. The wings 17 are preferably mounted as a support structure for the innermost cylinder 23, either directly or via a protective part 15 according to Fig. 3 64978; the latter is, in most practical cases, sufficiently strong for attachment purposes. Alternatively, the vanes 17 can be attached to a shield 14 or a cylinder 22. The exhaust inlet duct 18 terminates in front of the spark breaker 17 and is smaller in diameter than the muffler 13, so that the inlet duct 18 forms a connection 19 to the convection part 21.
Pakokaasukattila toimii seuraavaan tapaan: Säätö-pellin 12 ollessa auki pakokaasut kulkevat sisääntulokana-10 vasta kipinänsärkijän 17 kautta yhdistettyyn äänenvaimen-ninohituskanavaan 13 ja poistuvat poistoaukosta 3. Kun säätöpeltiä 12 käännetään kiinniasentoon päin, ohituksen virtausvastus kasvaa ja osa pakokaasuista ohjautuu aukon 19 kautta putkikierukoiden 11 muodostamaan konvektio-osaan.The exhaust boiler operates as follows: When the control damper 12 is open, the exhaust gases only pass through the inlet duct 10 through the spark arrester 17 to the connected muffler bypass duct 13 and exit the outlet 3. When the damper 12 is turned to the closed position a convection section.
15 Kun säätöläppä 12 on kiinniasennossa, kulkevat kaikki pakokaasut konvektio-osan kautta. Äänenvaimentimen ja tulokana-van välisen aukon 19 suuruus määräytyy pakokanaviston vastuksen ja moottorin ominaisuuksien perusteella. Aukko 19 mitoitetaan mahdollisimman pieneksi, jotta kattilan ohituk-20 sen ollessa päällä konvektio-osaan menevä virtaus jää pieneksi .15 When the control flap 12 is in the closed position, all exhaust gases pass through the convection section. The size of the opening 19 between the muffler and the inlet duct is determined by the resistance of the exhaust duct and the characteristics of the motor. The opening 19 is dimensioned as small as possible so that the flow to the convection section remains small when the boiler bypass is on.
Siinäkin tapauksessa, että säätöpelti 12 on kokonaan kiinni, saavutetaan pakokaasujen kattilan alaosassa ja äänen-vaimentimessa tapahtuvan suunnanmuutoksen ansiosta varsin 25 tehokas äänenvaimennus.Even in the case where the control damper 12 is completely closed, a fairly effective sound attenuation is achieved due to the change of direction in the lower part of the exhaust boiler and in the silencer.
Kattilan yläosa on muotoiltu siten, että ohituskana-van ja konvektio-osan liitoskohdassa virtausvastus on negatiivinen, jolla estetään pakokaasujen virtaus väärään suuntaan .The upper part of the boiler is shaped so that at the junction of the bypass duct and the convection part the flow resistance is negative, which prevents the flow of exhaust gases in the wrong direction.
30 Kipinänsärkijästä 17 kertyvä lika ja kattilaa puh distettaessa irtoava karsta samoin kuin mahdollinen vuoto-vesi valuvat kattilan pöhjakartioon, josta se voidaan poistaa putkiyhteen 10 kautta.30 The dirt accumulating from the spark breaker 17 and the scale that comes off when the boiler is cleaned, as well as any leakage water, flow into the bottom cone of the boiler, from where it can be removed through the pipe connection 10.
On selvää, että keksinnön mukainen laite voidaan to-35 teuttaa myös yksityiskohtia muuttamalla. Esim. kipinänsärki jän 17 tyyppiä voidaan muuttaa toiseksi, äänenvaimentimes-ta 13 voidaan jättää sisälieriö 23 pois tai virtaus konvektio- tlIt is clear that the device according to the invention can also be implemented by changing the details. For example, the type of spark plug 17 can be changed to another, the inner cylinder 23 can be omitted from the muffler 13 or the flow from convection can be omitted.
JJ
5 64978 osaan voidaan estää järjestämällä kattila useampi vetoiseksi tai käytetän säätöpeltiä, joka sulkee sekä ohituksen että konvektio-osan virtauksen. Keksintöä voidaan luonnollisesti myös soveltaa poikkileikkaukseltaan suorakaiteen muo-5 toiseen kattilaan; käsite "rengastila" ei siis rajoitu vain ympyränrenkaaseen.5 64978 parts can be prevented by arranging the boiler for more draft or by using a damper that shuts off the flow of both the bypass and the convection part. The invention can, of course, also be applied to a second boiler of rectangular cross-section; the concept of "ring space" is thus not limited to a circular ring.
