Description

Beschreibung description
Wärmedämmung für Turbinengehäuse Thermal insulation for turbine housing
Die Erfindung betrifft ein Turbinengehäuse nach dem Oberbeg¬ riff des Patentanspruchs 1. The invention relates to a turbine housing according to the Oberbeg ¬ reef of claim 1.
Turbinengehäuse, insbesondere Turbinengehäuse von Dampfturbi¬ nen werden üblicherweise gegenüber der Umgebung wärmegedämmt. Derzeit erfolgt die Wärmedämmung bei Dampfturbinen durch das Anbringen mehrlagiger Dämmmatten. Die Dämmmatten werden dabei mittels Drahthaken untereinander verbunden. Am Unterteil der Turbine besteht allerdings das Problem, dass die Dämmmatten häufig aufgrund der Schwerkraft nicht vollständig formschlüs¬ sig am Turbinengehäuse anliegen. Um das Anliegen der Dämmmat¬ ten zu gewährleisten, werden die Dämmmatten an ausgewählten Stellen mittels Drähten mit dem Turbinengehäuse verbunden. Trotz dieser Maßnahme kann nicht vollkommen verhindert werden, dass sich ein Luftspalt zwischen den Dämmmatten und dem Turbinengehäuse ausbildet. In diesem Luftspalt treten vaga¬ bundierende Luftströme auf, welche zu erheblichen Temperatur¬ differenzen im Turbinengehäuse führen. Verkrümmungsgefährdete Turbinen werden deshalb häufig mit Turbinegehäuseunterteil¬ heizungen ausgestattet. Diese sind jedoch sehr aufwendig und teuer . Turbine housing, in particular turbine casing of steam turbines ¬ nen are usually insulated from the environment. Currently, the thermal insulation of steam turbines by attaching multi-layer insulation mats. The insulating mats are connected to each other by means of wire hooks. At the lower part of the turbine, however, there is the problem that the insulating mats often do not rest completely formschlüs ¬ sig on the turbine housing due to gravity. In order to ensure the concern of Dämmmat ¬ th, the insulating mats are connected at selected points by means of wires to the turbine housing. Despite this measure can not be completely prevented that forms an air gap between the insulating mats and the turbine housing. In this air gap occur vaga ¬ bundierende air flows, which lead to significant temperature ¬ differences in the turbine housing. Verkrümmungsgefährdete turbines are therefore often equipped with turbine housing base ¬ heaters. However, these are very expensive and expensive.
Eine weitere Möglichkeit das Turbinengehäuse Wärme zu dämmen besteht darin, eine Spritzisolierung am Turbinengehäuse aus¬ zubilden. Die Spritzisolierung bietet eine hohe und sehr homogene Wärmedämmung. Nachteil der Spritzisolierung ist jedoch, dass diese im Servicefall nur sehr schwer demontiert werden kann. Die Spritzisolierung muss dabei üblicherweise zerstört werden. Another way to insulate the turbine housing heat is to form a splash insulation on the turbine housing ¬ . The splash insulation offers a high and very homogeneous thermal insulation. Disadvantage of spray insulation, however, is that it can be very difficult to dismantle in case of service. The splash insulation usually has to be destroyed.
Aufgabe der vorliegenden Erfindung ist daher, ein Turbinengehäuse mit einer Wärmedämmung bereitzustellen, die eine homogene und gleichmäßige Wärmedämmung ermöglicht und die im Ser¬ vicefall leicht demontiert werden kann. Die Aufgabe wird durch die Merkmale des unabhängigen Patenan spruchs 1 gelöst. Object of the present invention is therefore to provide a turbine housing with a thermal insulation, which allows a homogeneous and uniform thermal insulation and which can be easily disassembled in Ser ¬ vicefall. The object is achieved by the features of the independent patent claim 1.
Weitere Vorteile der Erfindung, die einzeln oder in Kombina¬ tion miteinander eingesetzt werden können, sind Gegenstand der Unteransprüche. Further advantages of the invention which can be used singly or in combina ¬ tion to each other are subject of the subclaims.
Das erfindungsgemäße Turbinengehäuse mit wenigstens einer Dämmmatte zur Wärmedämmung der Turbinengehäuseaußenseite ge¬ genüber der Umgebung zeichnet sich dadurch aus, dass zumindest bereichsweise eine gasundurchlässige Hülle an der Außen seite der Dämmmatte angeordnet ist. Die gasundurchlässige Hülle an der Außenseite der Dämmmatte verhindert, dass Luft von außen durch die Matte diffundieren bzw. an den Matten vorbei in den Spalt zwischen der Dämmmatte und der Turbinengehäuseaußenseite strömen kann. Hierdurch werden vagabundie¬ rende Luftströme im Spalt zwischen der Dämmmatte und der Tur binengehäuseaußenseite verhindert, und es wird eine verbes¬ serte Wärmedämmung erreicht. The turbine housing according to the invention with at least one insulating mat for thermal insulation of the turbine housing outside ge ¬ compared to the environment is characterized in that at least partially a gas-impermeable envelope is arranged on the outer side of the insulating mat. The gas-impermeable envelope on the outside of the insulating mat prevents air from diffusing from outside through the mat or flowing past the mats in the gap between the insulating mat and the turbine housing outside. As a result, vagabundie ¬ ing air currents in the gap between the insulating mat and the door binengehäuseaußenseite be prevented, and it is a verbes ¬ serte heat insulation achieved.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, das die gasundurchlässige Hülle zumindest an der Unterseite des Turbinengehäuses angeordnet ist. Wie bereits erwähnt, ent¬ steht gerade an der Turbinengehäuseunterseite, aufgrund der Schwerkraft, ein Luftspalt zwischen der Außenseite des Turbi negehäuses und den Dämmmatten. Das Anbringen einer gasundurchlässigen Hülle an der Unterseite des Turbinengehäuses hat somit einen besonders großen Effekt auf die Wärmedämmung An der Turbinengehäuseoberseite liegen die Dämmmatten norma¬ lerweise gut an, so dass hier eine gasundurchlässige Hülle nicht unbedingt erforderlich ist. An advantageous embodiment of the invention provides that the gas-impermeable envelope is arranged at least on the underside of the turbine housing. As already mentioned, ent ¬ is just at the turbine housing lower side, due to gravity, an air gap between the outside of the Turbi negehäuses and insulation mats. Attaching a gas-impermeable sleeve at the base of the turbine housing thus has a particularly large effect on the thermal insulation on the turbine housing top are the insulation mats norma ¬ mally good, so that a gas-tight envelope is not absolutely necessary here.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass die gasundurchlässige Hülle derart angeordnet ist, dass eine LuftZirkulation zwischen dem Turbinegehäuseaußenseite und der Dämmmatte unterbunden ist. Hierzu ist es erfor derlich dass die gasundurchlässige Hülle die Wärmedämmung zu mindest im Bereich der Turbinengehäuseunterseite vollständig überdeckt. Nur so kann verhindert werden, dass keine Luft in den Spalt zwischen Turbinengehäuseunterseite und der Dämmung gelangt. Die gasundurchlässige Hülle kann dabei vorzugsweise auf die Dämmmatten aufgeklebt werden. Ein besonders gutes Er¬ gebnis erzielt man, wenn die gasundurchlässige Hülle stirn¬ seitig so am Turbinengehäuse angeordnet ist, dass auch von dieser Seite keine Luft in den Luftspalt zwischen Turbinenge¬ häuse und Dämmmatte gelangen kann. Hierzu kann die gasun¬ durchlässige Hülle beispielsweise unmittelbar mit dem Turbi¬ nengehäuse verklebt werden. A further preferred embodiment of the invention provides that the gas-impermeable envelope is arranged such that an air circulation between the turbine housing outside and the insulating mat is prevented. For this purpose, it is neces sary that the gas-impermeable envelope to the thermal insulation completely covered at least in the area of the turbine housing underside. This is the only way to prevent air from getting into the gap between the turbine housing underside and the insulation. The gas-impermeable envelope can preferably be glued to the insulating mats. A particularly good He ¬ result is achieved if the gas-tight shell is arranged end-side ¬ so the turbine housing so that no air can enter into the air gap between Turbinenge ¬ housing and insulating mat also from this side. For this purpose, the gasun ¬ permeable shell can be glued, for example, directly to the Turbi ¬ nengehäuse.
Durch die Verwendung der gasundurchlässigen Hülle, welche an der Außenseite der Wärmedämmmatten angeordnet ist, kann somit zuverlässig ein vagabundierender Luftstrom zwischen der Tur- binengehäuseaußenseite und den Dämmmatten, insbesondere im unteren Teil des Turbinengehäuses, verhindert werden. Hier¬ durch treten die sonst üblichen Temperaturdifferenzen am Turbinengehäuse nicht oder wesentlich verminderter auf. Durch die Verwendung einer günstigen gasundurchlässigen Hülle kann somit die Verkrümmungsgefahr bei Turbinengehäuse vermieden werden und es kann auf teurere Lösungen beispielsweise Turbi- nengehäuseunterheizungen vollständig verzichtet werden. Im Servicefall kann die gasundurchlässige Hülle leicht von den Dämmmatten abgenommen werden und nach dem Service wieder angebracht werden. The use of the gas-impermeable sheath, which is arranged on the outside of the heat-insulating mats, thus reliably prevents a stray air flow between the turbine housing exterior and the insulating mats, in particular in the lower part of the turbine housing. Here ¬ by the usual temperature differences on the turbine housing do not occur or much less. The use of a favorable gas-impermeable envelope thus avoids the risk of distortion in turbine housings and expensive solutions, for example turbine housing underheating, can be completely dispensed with. In case of service, the gas-impermeable sheath can be easily removed from the insulation mats and attached again after service.
Ausführungsbeispiele und weitere Vorteile der Erfindung wer¬ den nachfolgend anhand der schematischen Zeichnungen erläutert. Es zeigen: Exemplary embodiments and further advantages of the invention who the ¬ explained below with reference to the schematic drawings. Show it:

Gleiche bzw. funktionsgleiche Bauteile sind figurübergreifend mit denselben Bezugszeichen versehen. Figure 2 shows an inventive turbine housing with a ga ¬ sundurchlässigen sleeve at the base of the Turbi ¬ nengehäuses. The same or functionally identical components are cross-figured with the same reference numerals.
Figur 1 zeigt ein Turbinengehäuse 1 wie es heutzutage bei Turbinen, insbesondere Dampfturbinen, eingesetzt wird. DasFIG. 1 shows a turbine housing 1 as it is used today in turbines, in particular steam turbines. The
Turbinengehäuse 1 ist üblicherweise zweiteilig ausgeführt und besteht aus einem Turbinengehäuseunterteil 1' und einem Tur- binengehäuseoberteil 1'', die über eine Flansch miteinander verbunden sind. Um das Turbinengehäuse gegenüber der Umgebung Wärme zu dämmen und so Wärmeverluste zu vermeiden, sind um das Turbinengehäuse herum, Wärmedämmmatten 2 angeordnet. Üb¬ licherweise sind die Wärmedämmmatten in mehreren Schichten angeordnet, dergestalt, dass der Spalt an der Stirnseite zweier aufeinander treffenden Dämmmatten 2 durch eine über dem Spalt angeordneten Dämmmatte 2 verdeckt ist. Die einzel¬ nen Wärmedämmmatten 2 sind untereinander mit Drahthaken verbunden. Aufgrund der Schwerkraft werden die Dämmmatten 2 an der Unterseite des Turbinengehäuses 1 nach unten gezogen, wo¬ durch sich zwischen der Turbinengehäuseaußenseite 3 und den Dämmmatten 2 ein Spalt 5 einstellt. Innerhalb dieses Luft¬ spaltes 5 kann Luft vagabundieren und dadurch eine effektive Wärmedämmung verhindern. Die Luft gelangt dabei durch Diffusion und durch Spalte in der Wärmedämmung (angedeutet durch die Pfeile in Fig.l) in den Spalt 5. Turbine housing 1 is usually designed in two parts and consists of a turbine housing lower part 1 'and a turbinengehäuseoberteil 1'', which are interconnected via a flange. In order to insulate the turbine housing from the surrounding heat and thus avoid heat losses, heat-insulating mats 2 are arranged around the turbine housing. Ov ¬ SHORT- the heat insulating panels are arranged in multiple layers, such that the gap at the end face of two clashing insulating mats is covered by an insulation mat arranged above the gap 2. 2 The individual ¬ nen thermal insulation mats 2 are interconnected with wire hooks. Due to gravity, the insulating mats 2 are pulled down on the underside of the turbine housing 1, where ¬ through a gap 5 sets between the turbine housing outside 3 and the insulating mats 2 ¬ . Within this air gap 5 ¬ air can wander and thereby prevent effective heat insulation. The air passes through diffusion and through gaps in the thermal insulation (indicated by the arrows in Fig.l) in the gap. 5
Figur 2 zeigt das erfindungsgemäße Turbinengehäuse 1. Im Ge¬ gensatz zu dem in Figur 1 beschriebenen Turbinengehäuse ist hier an der Unterseite des Turbinengehäuses 1 eine gasun¬ durchlässige Hülle 4 angeordnet. Die gasundurchlässige Hülle 4 umschließt die Dämmmatten 2 am Turbinengehäuseunterteil 1' vollständig. Die gasundurchlässige Hülle 4 ist vorzugsweise auf die Dämmmatten 2 aufgeklebt. Um ein stirnseitiges Ein¬ dringen der Luft in den Spalt 5 zu verhindern, wird die gasundurchlässige Hülle 4 stirnseitig mit dem Turbinengehäuse 1 verklebt (in der Figur nicht dargestellt) . Figure 2 shows the turbine housing according to the invention 1. In Ge ¬ contrast to the process described in Figure 1 a turbine housing gasun ¬ permeable cover 4 is here arranged on the underside of the turbine housing. 1 The gas-impermeable shell 4 encloses the insulating mats 2 on the turbine housing lower part 1 'completely. The gas-impermeable envelope 4 is preferably glued to the insulating mats 2. A frontal A ¬ penetrate the air in the gap 5 to prevent the gas-impermeable sleeve 4 is bonded to the front side (not shown in the figure) to the turbine housing. 1
Die gasundurchlässige Hülle 4 verhindert somit wirkungsvoll das Eindringen von Luft in den Spalt 5. Dabei wird sowohl ei- ne Luftströmung um die Dämmmatten 2 herum als auch eine Diffusion von Luft durch die Dämmmatten 2 selbst verhindert. Die gasundurchlässige Hülle 4 verhindert somit das vagabundieren von Luft im Spalt 5 zwischen der Turbinengehäuseaußenseite 3 und den Dämmmatten 2. Ein Spalt 5 zwischen dem Turbinengehäuse 1 und den Dämmmatten 2 ist somit zu tolerieren. Das Anbringen der gasundurchlässigen Hülle 4 kann auch bei bereits vorhandenen Turbinengehäusen 1 erfolgen, so dass sich bestehende Anlagen auf einfache Weise nachrüsten lassen. Die ga¬ sundurchlässige Hülle 4 kann somit teure und aufwendige Lö¬ sungen zur Reduzierung von Temperaturdifferenzen am Turbinengehäuse ersetzen. The gas-impermeable sheath 4 thus effectively prevents the ingress of air into the gap 5. ne air flow around the insulating mats 2 around and prevents diffusion of air through the insulating mats 2 itself. The gas-impermeable sheath 4 thus prevents the straying of air in the gap 5 between the turbine housing outside 3 and the insulating mats 2. A gap 5 between the turbine housing 1 and the insulating mats 2 is thus to be tolerated. The installation of the gas-impermeable casing 4 can also be carried out in existing turbine housings 1, so that can be retrofitted existing facilities in a simple manner. The ga ¬ sundurchlässige sheath 4 can replace expensive and complex Lö ¬ solutions for the reduction of temperature differences on the turbine housing.
