Description

Die Erfindung bezieht sich auf die Anordnung vorn Wärmeaiustiauschern ian Brennkammern., bei- spielsweise für Gasturbinen, in Form eines die Brennkammer umgebendien Hohlzylinders. Bei den bekannten Ausführungen dieser Art sind in dem Hohlzylinder ,gerade Rohrleitungen vorge- sehien,, diurch welche das heiße Medium fließt, wäh- rend das Kühlmittel diesle Rohre umstreicht. Gemäß der Erfindunig kann ,der Wärmeaausta:usch erhöht werden, wenn die Gas- und Luftkanäle im Wäxmieaustauscher gekrümmt sind, beispielsweise können -die Gas- und Luftkanäle die Brennkammer schraubenförmig umgeben. In dem zwischen dem Mantel -der Brennkammer und dem rin,gföiimigen Wärxneaiustiaiuscher lauf bekannte Weisie angeord- netem, Luftspalt ist leine zylindrische, sich im we.- serntlichen übler die ,ganze Länge !der Brennhammer erstreckende Blechwand ;angeordnet, um, Wärme- strahlung lauf .den Wärmeaustauscher zu verhindern. In Üer Zeichnung, welche eine beispielsweise Aus- führung -der Erfindung zeigt, ist Fig. i ein teilweiser Längsschnitt durch eine Bremnk=m@er seiner Glasturbine mit .dem. sie um- gebenden Bauteilen, Fig. 2 ein Schnitt nach -der Linie II-II der Fig. i und Fig.3 lein Schnitt nach -der Linie III-III der Fig. i. Die Gasturbine kann .eine -oder mehrere Breinn- kamrnern enthalten. Die Brennkammer i weist einen diese umgebenden Brennkammermiantel2 auf. Der Wärmieaustiaiu.scher 3 -umgibt die Brennkammer schraiub-enförmiig und ist von .einem Gehäuse q. um- schlossen. Der innere Durchmesser des Wärmeiaus- tau:schers ist ,größer ia1s -der äußere Durchmesser des Bnennkammermantels, wodurch Bein. Luftspalt 5 rings um ,die Brennkammer gebildet wird. Dias Ge- häiuse wird -durch Deckel 6 rund 7 !an den Enden ub- geschlossen. Durch idiesie Ausbildung tritt eine Erhöhung des Wärmeaustausches lein, da die Gas: und. Luftkanäle im Wärmeaustauscher biet schraubenförmig die Brennkammer umgebenden Wärmea:ustauschern ge- krümmt sind. Es wird dadurch eine in geraden Rohren: bestehende laminare Strömung in eine turbulente Strömung umgewandelt. Die vom Lader komprimierte Luft strömt durch -dien: Stutzen 8 in dien Wär"anieaustauscher, wird in diesiem spiralfö@tmig Zum die Brennkammer ;geführt rund bei 9 in die Brennkammergeleitet. Von der Brennkammer führt eine Leitung i o beispielsweise zu einer Lader- und Nutzturbine T, welche .durch die Brenngase be- trieben wird. Die Abgase werden durch :den Stutzen i i in, dien Wärmeaustiauscher ,geführt und verlassen diesen, senkrecht zur Zeichernehene -durch leinen. Stutzen 12. Um eine Wärmestrahlung sauf den Wärmeaus- bajuscher wirkungsvoll zu verhindern, ist -es auch möglich, in den Luftspalt zwischen -dem Brenn- kammermamtel iurnd,dien ringförmig diesen -umgeben- dien Wärxrneaustauscher,einen Blechzylinder 13 anzu- ordnen. Dadurch entsteht lein Iselierfilm zwischen dem Blechzylindler 13 und dem Mantel 2 der Brenn- kammer und zwischen dem Blieehzylind,er 13 -und dem Wärmeajwstajwscher 3. Dier Blechzylinder wird bei- spielsweise -durch zwischen -dem Mantel. der Brenn- kanrnmer- und -dem Wärmeaustauscher angeordnete Blechstücke 1q. in Lage gehalten. Es sind zahlreiche Ausführungen von Wärmeaus- taiuschem, bekainnt, und die Erfindung ist nicht auf eine bestimmte Ausführung beschränkt, weshalb in der Zeichnung idie Ausbildung des Wärmuaus- tauschers nur ianigedautet ist. Wenn mehrere Brenn- kammern vorgesehen sind, kann jede der Brenn- kammern, von einem Wä,rmeaaustauscher @umgeben sein., -oder ies können sämtliche Bnenäkammern von einem ieinzügen Wärmeaustauscher umgeben stein. Dies richtet sich nach dem baulichen Anforderungen. The invention relates to the arrangement front heat exchangers in the combustion chambers., both for example for gas turbines, in the form of a die Combustion chamber surround the hollow cylinder. In the known designs of this type are in the hollow cylinder, straight pipelines see, through which the hot medium flows, while- rend the coolant brushes these pipes. According to the invention, the heat exchange be increased if the gas and air channels in the Heat exchangers are curved, for example -The gas and air ducts can open the combustion chamber surrounded helically. In the one between the Jacket - the combustion chamber and the rin, approve Warmth-of-life run, well-known wisdom netem, air gap is cylindrical, in the white the whole length of the hammer extending sheet metal wall; arranged to, heat to prevent radiation from running through the heat exchanger. In the drawing, which shows an example Leadership of the invention shows is Fig. I is a partial longitudinal section through a Bremnk = m @ er his glass turbine with .dem. she um- giving components, FIG. 2 shows a section along line II-II in FIG and Fig.3 is a section along the line III-III of the Fig. I. The gas turbine can have one or more chambers included. The combustion chamber i has a these surrounding combustion chamber envelopes2. Of the Heat exchanger 3 surrounds the combustion chamber screw-shaped and has a housing q. around- closed. The inner diameter of the heat exchanger tau: schers is, larger ia1s - the outer diameter of the nominal chamber jacket, whereby leg. Air gap 5 all around, the combustion chamber is formed. Slides häiuse is -by cover 6 around 7! at the ends ub- closed. Through this training there is an increase in the Heat exchange because the gas: and. Air ducts in the heat exchanger offers the Heat exchangers surrounding the combustion chamber are curved. This makes it a straight line Pipes: existing laminar flow into one turbulent flow converted. The one from the loader Compressed air flows through -serve: port 8 in The heat exchanger is spiral-shaped in this one To the combustion chamber; led around at 9 into the Combustion chamber routed. Leads from the combustion chamber a line io for example to a loader and Power turbine T, which. is driven. The exhaust gases pass through: the nozzle ii in, the heat exchanger, led and left Line this perpendicular to the drawing line. Nozzle 12. In order to generate heat radiation on the heat It is also possible to prevent bajuscher effectively possible, in the air gap between -the burner- Kammermamtel iurnd, serve in a ring around this -surrounding- serve the heat exchanger to attach a sheet metal cylinder 13 put in order. This creates no isolation film between the sheet metal cylinder 13 and the jacket 2 of the combustion chamber and between the lead cylinder, he 13 and the Wärmeajwstajwscher 3. The sheet metal cylinder is for example -by between -the coat. the burning arranged in the form of a heat exchanger and heat exchanger Sheet metal pieces 1q. kept in position. There are numerous designs of heat taiuschem, well known, and the invention is not up limited to a certain execution, which is why in the drawing i the formation of the heat dissipation tauschers is only ianigedautet. If several burners chambers are provided, each of the combustion chambers, @surrounded by a heat exchanger be., -or these can be all Bnenä chambers of a single-draw heat exchanger surrounded by stone. This depends on the structural requirements.
