Opfindelsen vedrører en udstødsgaskedel omfattende en konvektionssektion udformet som et ringformet rum indeholdende vandrørsspiraler og en bypass-kanal for udstødsgasser og udformet som en cylinder omgivet af 5 konventionssektionen, hvilken bypass-kanal samtidig virker som lyddæmper.The invention relates to an exhaust gas boiler comprising a convection section designed as an annular space containing water pipe coils and a bypass duct for exhaust gases and designed as a cylinder surrounded by the convention section, which bypass duct simultaneously acts as a silencer.
Fra NO patentskrift nr. 95 887 kendes en udstødsgaskedel af den i indledningen angivne art. Denne kedel har ved indløbet til konvektionssektionen, respektive 10 bypass-kanalen en gliderventil, der i sin ene yderstilling lukker helt for konvektionssektionen og åbner helt for bypass-kanalen og i sin anden yderstilling åbner helt for konvektionssektionen og lukker helt for bypass-kanalen. I mellemstillinger er de respektive indløb åb-15 net stort set svarende til ventilens vandring. For at forhindre tilbagestrømning af udstødsgas fra bypass-kanalen eller lyddæmperen til konvektionssektionen er lyddæmperen forsynet med et separat udløb til fri luft.NO patent specification no. 95 887 discloses an exhaust gas boiler of the type stated in the introduction. At the inlet to the convection section and the bypass duct, respectively, this boiler has a slide valve which in its one extreme position closes completely to the convection section and opens completely to the bypass duct and in its other extreme position opens completely to the convection section and closes completely to the bypass duct. In intermediate positions, the respective inlets open are substantially similar to the travel of the valve. To prevent the backflow of exhaust gas from the bypass duct or muffler to the convection section, the muffler is provided with a separate outlet for free air.
Denne kendte kedel har den ulempe, at der ikke fås nogen 20 lyddæmpning, når gliderventilen lukker for bypass-kanalen .This known boiler has the disadvantage that no sound attenuation is obtained when the slide valve closes the bypass duct.
Udstødskedelen ifølge opfindelsen adskiller sig fra den kendte ved, at forbindelsen mellem kedelens tilgangskanal for udstødsgas og konvektionssektionen er 25 udformet således, at den har en strømningsmodstand, der er betydelig højere end strømningsmodstanden i forbindelsen mellem tilgangskanalen og bypass-kanalen, og at et reguleringsmiddel er indrettet i bypass-kanalen ved dennes afgangsende.The exhaust boiler according to the invention differs from the known one in that the connection between the boiler inlet channel for exhaust gas and the convection section is designed so that it has a flow resistance which is considerably higher than the flow resistance in the connection between the inlet duct and the bypass duct, and that a regulating means is arranged in the bypass duct at its outlet end.
30 Herved opnås den væsentlige fordel, at bypass- kanalen virker lyddæmpende, selv når denne kanal er lukket for gennemstrømning af udstødsgas.Hereby the essential advantage is obtained that the bypass duct has a sound-absorbing effect, even when this duct is closed for the flow of exhaust gas.
Yderligere karakteristiske træk ved udstødskedelen ifølge opfindelsen fremgår af underkravene.Further characteristic features of the exhaust boiler part according to the invention appear from the subclaims.
35 I det følgende forklares opfindelsen mere de taljeret med henvisning til en foretrukket udførel- aaa^rt-rim tt i e t Ί nrron f'.'rnrIn the following, the invention will be explained in more detail with reference to a preferred embodiment of the rhyme in the art.
DK 152069 BDK 152069 B
2 fig. 1 er e-t sidebillede af kedelen, fig. 2 et planbillede af kedelen, og fig. 3 et længdesnit i kedelen.2 fig. 1 is a side view of the boiler, FIG. 2 is a plan view of the boiler, and FIG. 3 is a longitudinal section of the boiler.
I fig. 1 betegner 1 kedelens ydervæg, 2 og 3 5 betegner en tilgangs- henholdsvis en afgangsåbning for udstødsgas. 4 er til- og af gangsman! fold for vand, og 5 en sikkerhedsventil. Kedelens fastgørelsesbeslag er betegnet med 6, og et manometer med 7. En drivmekanisme for et bypass-reguleringsspjæld 12 er betegnet 10 med 8, og mandehulslemme på toppen af kedelen er betegnet med 9. I kedelens nederste konus er et manifold 10, fra hvilket kedelvaskevand og vand lækkende fra en konvektionssektion kan løbe ud.In FIG. 1 denotes 1 the outer wall of the boiler, 2 and 3 5 denote an inlet and an outlet opening for exhaust gas, respectively. 4 is on and off gangsman! fold for water, and 5 a safety valve. The boiler mounting bracket is denoted by 6, and a manometer by 7. A drive mechanism for a bypass control damper 12 is denoted by 10, and manhole door on top of the boiler is denoted by 9. In the lower cone of the boiler is a manifold 10, from which boiler wash water and water leaking from a convection section may run out.
Fig. 3 viser en konvektionssektion 21, der inde-15 holder vandrørsspiraler 11. Konvektionssektionen 21 er ringformet, hvorved der dannes en bypass-kanal 13 for udstødsgas i cylinderen 22, der er omgivet af sektionen 21. Cylinderen 22 er beklædt med et lydabsorberende materiale 16, f.eks. glasuld, oven på hvilket der er 20 monteret en beskyttende membran og en perforeret stålplade 14. Til forbedring af lyddæmpningen er der i cylinderen 22 indrettet en anden cylinder 23 med lydabsorberende materiale 16 og beskyttende beklædning 15.FIG. 3 shows a convection section 21 containing water pipe coils 11. The convection section 21 is annular, thereby forming an bypass duct 13 for exhaust gas in the cylinder 22 surrounded by the section 21. The cylinder 22 is lined with a sound absorbing material 16, for example. glass wool, on top of which a protective membrane and a perforated steel plate 14 are mounted. To improve the sound attenuation, a second cylinder 23 with sound-absorbing material 16 and protective clothing 15 is arranged in the cylinder 22.
25 Bypass-reguleringsspjældet eller klappen 12 er monteret i et rør 20 forbundet til den øverste ende af den lyddæmpede bypass-kanal 13, hvorved spjældet 12’s aksel bliver kort, og lejerne kan placeres uden for kedelen.The bypass control damper or flap 12 is mounted in a pipe 20 connected to the upper end of the muffled bypass duct 13, whereby the shaft of the damper 12 becomes short and the bearings can be placed outside the boiler.
30 Ledeskovle 17 i den nederste del af bypass- kanalen 13 virker som gnistfangere. Ledeskovlene ind-bygges fortrinsvis således, at de virker som en bærende understøtning for den inderste cylinder, enten direkte eller ifølge fig. 3 via den beskyttende del 15; denne 35 sidstnævnte del er i de fleste i praksis forekommende udførelsesformer tilstrækkelig kraftig til dette formål.Guide vanes 17 in the lower part of the bypass channel 13 act as spark arrestors. The guide vanes are preferably built in so that they act as a load-bearing support for the inner cylinder, either directly or according to fig. 3 via the protective part 15; this latter part is in most practical embodiments sufficiently powerful for this purpose.

Alternativt kan ledeskovlene 17 være monteret på den beskyttende del 14 eller på cylinderen 22. Et tilgangs-5 rør 18 for udstødsgas ender foran gnistfanget 17 og har en mindre diameter end den lyddæmpende kanal 13, således at der skabes en forbindelse 19 fra tilgangsrøret 18 til konvektionssektionen 21.Alternatively, the guide vanes 17 may be mounted on the protective part 14 or on the cylinder 22. An exhaust gas supply pipe 18 ends in front of the spark arrestor 17 and has a smaller diameter than the sound-absorbing channel 13, so that a connection 19 is created from the inlet pipe 18 to the convection section 21.
Udstødsgaskedelen virker på følgende måde: Når 10 reguleringsspjældet 12 er åbent, passerer udstødsgas fra tilgangsrøret 18 gennem gnistfaneet 17 til den kombinerede lyddæmper/bypass-kanal 13 og føres ud derfra gennem afgangsåbningen 3. Når reguleringsspjældet 12 drejes mod den lukkede stilling, forøges bypass'ets 15 strømningsmodstand, og en del af udstødsgassen afbøjes gernem åbningen 19 til konvektionssektionen dannet af rørspiralerne 11. Når reguleringsspjældet 12 er i den lukkede stilling, passerer al udstødsgas gennem konvektionssektionen. Størrelsen af åbningen 19 mellem lyd-20 dæmperen og tilgangsrøret fastsættes på basis af udstødsrørsystemets modstand og motorens egenskaber. Åbningen 19 udføres så lille som mulig, således at strømningen til konvektionssektionen er lille, når bypass'et er i den åbne stilling.The exhaust gas section operates as follows: When the control damper 12 is open, exhaust gas passes from the inlet pipe 18 through the spark fan 17 to the combined muffler / bypass duct 13 and is led out from there through the outlet opening 3. When the control damper 12 is rotated towards the closed position, the bypass increases and a portion of the exhaust gas is deflected through the opening 19 of the convection section formed by the tubular coils 11. When the control damper 12 is in the closed position, all the exhaust gas passes through the convection section. The size of the opening 19 between the muffler and the inlet pipe is determined on the basis of the resistance of the exhaust pipe system and the characteristics of the motor. The opening 19 is made as small as possible, so that the flow to the convection section is small when the bypass is in the open position.
25 Selv i tilfælde af at reguleringsspjældet 12 er fuldstændig lukket, opnås en meget effektiv lyddæmpning takket være de ændringer af gasstrømmens retning, der finder sted i den nederste del af udstødsgaskedelen og lyddæmperen.Even in the case that the control damper 12 is completely closed, a very effective sound attenuation is obtained thanks to the changes of the direction of the gas flow which take place in the lower part of the exhaust gas part and the muffler.
30 Den øverste del af kedelen er formet således, at strømningsmodstanden ved overgangen mellem bypass-kanalen og konvektionssektionen forhindrer strømning af udstødsgas i den forkerte retning.The upper part of the boiler is shaped so that the flow resistance at the transition between the bypass duct and the convection section prevents the flow of exhaust gas in the wrong direction.
Urenheder akkumuleret fra gnistfanget 17 og be-35 lægning løsnet ved rensning af kedelen, såvel som eventuelt lækagevand strømmer til kedelens bundkonus, fra hvilken det fjernes gennem manifoldet 10.Impurities accumulated from the spark arrestor 17 and coating loosened by cleaning the boiler, as well as any leaking water flowing to the bottom cone of the boiler, from which it is removed through the manifold 10.
