Abstract

Assembly including an LP module (2) of a steam turbine supported by a concrete block (5) carried by posts of a concrete raft (9), and an enclosure (4) made up of an exhaust box (1) surrounding the LP module (2) and connected to the latter by impervious elastic seals (14) and of a condenser (3) equipped with bundles (8) located under the LP module (2) and resting on the raft (9), characterised in that the enclosure (4) is made of concrete. The casing (envelope) of the condenser made of concrete is therefore totally independent of the turbine and of the block which supports it. <IMAGE>

Description

Les turbines à vapeur qui fournissent de l'électricité sont habituellement à condensation et la vapeur qui s'échappe de la boîte échappement des modules basse pression est canalisée vers le condenseur situé sous la turbine.Steam turbines that supply electricity are usually condensing and the steam that escapes from the low pressure module's exhaust box is channeled to the condenser located under the turbine.

La boîte échappement 1 du module BP 2 et l'enveloppe du condenseur 3 forment une vaste enceinte sous vide 4 réalisée en tôles et renforcées par des tirants internes (voir figures 1 et 2).The exhaust box 1 of the BP module 2 and the casing of the condenser 3 form a large vacuum enclosure 4 made of sheets and reinforced by internal tie rods (see Figures 1 and 2).

La boîte d'échappement 1 et l'enveloppe 3 ont chacun un rôle bien spécifique :

  • - La boîte échappement 1 et le massif 5 sur lequel elle est en appui supportent la partie active de la turbine c'est-à-dire le rotor 6 et le corps BP 7. C'est cet ensemble qui conditionne par ses déformations permanentes ou variables le maintien des jeux radiaux rotor/corps BP, donc le bon comportement dynamique de la ligne d'arbre. La boîte échappement 1 canalise la vapeur vers les faisceaux 8 du condenseur 3.
  • - L'enveloppe du condenseur 3 en appui sur le radier 9 ne supporte que les charges statiques internes du condenseur 3 et en particulier les faisceaux 8 de condensation.
The exhaust box 1 and the casing 3 each have a very specific role:
  • - The exhaust box 1 and the block 5 on which it is supported support the active part of the turbine, that is to say the rotor 6 and the LP body 7. It is this assembly which conditions by its permanent deformations or variables the maintenance of the radial rotor / body clearances BP, therefore the good dynamic behavior of the shaft line. The exhaust box 1 channels the steam to the bundles 8 of the condenser 3.
  • - The envelope of the condenser 3 resting on the raft 9 only supports the internal static charges of the condenser 3 and in particular the bundles 8 of condensation.

La boîte échappement 1 et l'enveloppe du condenseur 3 sont reliées entre elles pourformer cette enceinte unique 4.The exhaust box 1 and the casing of the condenser 3 are connected together to form this single enclosure 4.

Si la liaison 12 est rigide (exemple: par soudage) l'enceinte 4 résiste aux efforts de pression externe, mais elle exerce des efforts variables sur les pattes d'appui 10 de la boîte échappement 1 ainsi que sur le radier 9 (voir figure 1); les efforts variables sont dus à la masse variable d'eau dans le condenseur et aux dilatations thermiques du condenseur. Ainsi lorsque le condenseur se refroidit les charges diminuent sur les ressorts 11 et augmentent sur les pattes d'appui.If the connection 12 is rigid (example: by welding) the enclosure 4 resists external pressure forces, but it exerts variable forces on the support legs 10 of the exhaust box 1 as well as on the slab 9 (see figure 1); the variable forces are due to the variable mass of water in the condenser and to the thermal expansions of the condenser. Thus when the condenser cools the charges decrease on the springs 11 and increase on the support legs.

Si la liaison 12 est élastique (figure 2) on a en fait deux enceintes "mécaniquement" séparées et les forces dues à la pression extérieure sont supportées ainsi que le poids du module BP par le massif 5 à travers les pattes d'appui 10 de la boîte échappement. La masse totale de l'enveloppe du condenseur 3 ainsi que les efforts dûs au vide sont supportés par le radier 9 de la fondation sans ressort interposé 11.If the connection 12 is elastic (FIG. 2) there are in fact two "mechanically" separate enclosures and the forces due to the external pressure are supported as well as the weight of the BP module by the block 5 through the support legs 10 of the exhaust box. The total mass of the envelope of the condenser 3 as well as the forces due to the vacuum are supported by the raft 9 of the foundation without interposed spring 11.

Ces deux configurations ne sont pas satisfaisantes puisqu'il y a toujours interférence et incompatibilité entre la fonction turbine/massif et la fonction condensation.These two configurations are not satisfactory since there is always interference and incompatibility between the turbine / solid function and the condensation function.

Tous les projets de réalisation d'enveloppe de condenseur en béton ont été réalisés sur la base de ces deux principes pratiquement indispensables lorsque le condenseur est situé sous la turbine basse pression. Ainsi le massif supportant la turbine et l'enveloppe du condenseur en béton sont intimement liés puisque l'on utilise l'infrastructure de l'un pour réaliser l'autre.All the concrete condenser shell construction projects have been carried out on the basis of these two practically essential principles when the condenser is located under the low pressure turbine. Thus the block supporting the turbine and the concrete condenser jacket are intimately linked since the infrastructure of one is used to produce the other.

Dans cet ensemble il y a donc interférence entre la fonction turbine/massif et la fonction condensation.In this assembly there is therefore interference between the turbine / solid function and the condensation function.

On conserve alors les inconvénients décrits précédemment lors d'utilisation d'enveloppe de condenseur en acier mais apparaissent en plus des déplacements d'ensemble massif/condenseur dûs aux températures internes variables du condenseur qui sont nuisibles au bon fonctionnement de la turbine.The disadvantages described above are then retained when using the steel condenser casing, but appear in addition to displacements of the massive assembly / condenser due to the variable internal temperatures of the condenser which are detrimental to the proper functioning of the turbine.

Pour réaliser un condenseur en béton ne présentant pas ces inconvénients, les inventeurs ont eu l'idée de modifier l'ensemble turbine à vapeur boîte d'échappement dans lequel la boîte d'échappement entoure le corps BP de façon étanche grâce à des joints souples.To make a concrete condenser that does not have these drawbacks, the inventors came up with the idea of modifying the exhaust box steam turbine assembly in which the exhaust box surrounds the LP body in a sealed manner using flexible seals .

La présente invention concerne un ensemble comportant un module BP de turbine à vapeur supporté par un massif en béton porté par des poteaux d'un radier en béton et une enceinte constituée d'une boîte échappement entourant le module BP et reliée à celui-ci par des joints étanches élastiques et d'un condenseur muni de faisceaux disposé sous le module BP et reposant sur le radier caractérisé en ce que l'enceinte est en béton.The present invention relates to an assembly comprising a LP steam turbine module supported by a concrete block carried by posts of a concrete slab and an enclosure consisting of an exhaust box surrounding the BP module and connected to it by elastic seals and a condenser provided with bundles placed under the BP module and resting on the slab, characterized in that the enclosure is made of concrete.

L'enveloppe de condenseur en béton est donc totalement indépendante de la turbine et du massif qui la supporte.The concrete condenser jacket is therefore completely independent of the turbine and the block that supports it.

Cette réalisation présente les avantages suivants :

  • - Structure de l'enveloppe très rigide en appui sur le radier.
  • - Structure pouvant être en appui sur des amortisseurs anti-sismique.
  • - Vibration réduite.
  • - Bruit réduit.
  • - Suppression des renforts internes nuisible à l'écoulement.
  • - Réduction du temps de fabrication de l'enveloppe du condenseur réalisée en même temps que le génie civil.
This realization has the following advantages:
  • - Structure of the very rigid envelope bearing on the raft.
  • - Structure that can be supported on anti-seismic shock absorbers.
  • - Reduced vibration.
  • - Reduced noise.
  • - Removal of internal reinforcements harmful to the flow.
  • - Reduction of the manufacturing time of the condenser casing carried out at the same time as civil engineering.

La présente invention sera mieux comprise à la lumière de la description qui va suivre dans laquelle :

  • Les figures 1 et 2 représentent des ensembles connus.
  • Les figures 3 et 4 représentent une vue de côté et une vue de face de l'ensemble selon l'invention.
  • La figure 5 représente un montage des faisceaux du condenseur.
  • La figure 6 représente une variante de la figure 5
The present invention will be better understood in the light of the description which follows in which:
  • Figures 1 and 2 show known assemblies.
  • Figures 3 and 4 show a side view and a front view of the assembly according to the invention.
  • Figure 5 shows an arrangement of the condenser bundles.
  • Figure 6 shows a variant of Figure 5

Lorsque le condenseur est situé sous la turbine basse pression le principe GEC ALSTHOM de structure BP à enveloppe indépendante permet de réaliser dans des conditions idéales une enceinte unique en béton comprenant une partie servant de boîte échappement et l'enveloppe du condenseur qui n'ait aucune interférence mécanique ou thermique avec la turbine basse pression.When the condenser is located under the low-pressure turbine, the GEC ALSTHOM principle of BP structure with independent casing makes it possible to produce under ideal conditions a single concrete enclosure comprising a part serving as an exhaust box and the condenser casing which has mechanical or thermal interference with the low pressure turbine.

En effet dans ce principe la boîte échappement n'a comme rôle que celui de canaliser la vapeur vers le condenseur, elle ne supporte ni le corps BP, ni le rotor comme dans les cas des figures 1 et 2.In fact, in this principle, the exhaust box only has the role of channeling steam to the condenser, it supports neither the LP body, nor the rotor as in the cases of FIGS. 1 and 2.

La fonction turbine est donc complètement séparée de la fonction recueil de vapeur et condensation.The turbine function is therefore completely separate from the steam collection and condensation function.

Le module BP 2 comporte le corps BP 7 qui supporte le rotor BP 6. Il est en appui sur le massif 5 (voir figures 3 et 4).The BP module 2 comprises the BP body 7 which supports the BP rotor 6. It is supported on the block 5 (see Figures 3 and 4).

Ce massif 5 est lui-même en appui sur les poteaux 26 par l'intermédiaire de ressorts 13. Il peut d'ailleurs être aussi lié rigidement aux poteaux 26. Les poteaux 26 sont intégrés au radier 9.This solid 5 is itself supported on the posts 26 by means of springs 13. It can also be rigidly connected to the posts 26. The posts 26 are integrated into the raft 9.

Le corps BP 7 traverse l'enceinte 4, boîte échappement 1 enveloppe du condenseur 3, et des joints élastiques circulaires 14 assurent l'étanchéité avec l'extérieur.The BP body 7 crosses the enclosure 4, exhaust box 1 casing of the condenser 3, and elastic circular seals 14 seal the exterior.

Le massif 5 ne supporte que la masse du module BP 2 de la turbine et il n'y a pas d'autres forces extérieures.The block 5 only supports the mass of the BP module 2 of the turbine and there are no other external forces.

La fonction condensation est réalisée par l'enceinte unique 4 en béton munie d'une peau interne 15 en tôle d'acier mince assurant l'étanchéité avec l'eau déminéralisée.The condensation function is carried out by the single concrete enclosure 4 provided with an internal skin 15 made of thin sheet steel ensuring sealing with demineralized water.

L'enceinte 4 comporte :

  • - la boîte échappement.
  • - l'enveloppe du condenseur 3.
The enclosure 4 comprises:
  • - the exhaust box.
  • - the casing of the condenser 3.

La nouvelle enveloppe unique en béton est réalisée en deux parties dont la ligne de coupure est le joint horizontal de la turbine suivant YY de manière à avoir accès à la turbine par démontage de la partie supérieure de cette enveloppe. L'étanchéité est assurée par un boulonnage et soudage d'une languette en acier ou bien par la mise en place d'un joint en mortier.The new single concrete casing is made in two parts, the cutting line of which is the horizontal joint of the turbine along YY so as to have access to the turbine by dismantling the upper part of this casing. Sealing is ensured by bolting and welding a steel tab or by placing a mortar joint.

Cette enceinte unique 4 est en appui sur le radier 9. Elle peut être :

  • - intégrée au radier 9,
  • - en appui sur le radier 9 avec juxtaposition d'amortisseurs 16 pour améliorer la tenue de l'ensemble aux accélérations dues à des séismes et faciliter les déplacements thermiques de l'enceinte 4.
This single enclosure 4 is supported on the raft 9. It can be:
  • - integrated into the raft 9,
  • - resting on the raft 9 with juxtaposition of shock absorbers 16 to improve the resistance of the assembly to accelerations due to earthquakes and facilitate the thermal displacements of the enclosure 4.

Les efforts dus au vide ou à la légère surpression sont repris directement par la structure en béton de l'enceinte unique 4.The forces due to the vacuum or the slight overpressure are taken up directly by the concrete structure of the single enclosure 4.

Les déplacements thermiques verticaux à partir du radier 9 sont possible sans induire d'effort sur le module basse pression 2 de la turbine grâce aux joints élastiques circulaires 14 qui assurent l'étanchéité entre celui-ci et l'enceinte 4.The vertical thermal displacements from the raft 9 are possible without inducing any effort on the low pressure module 2 of the turbine thanks to the elastic circular seals 14 which seal between it and the enclosure 4.

A noter que les charges sur le massif 5 sont strictement réduites à la masse du module BP 2, ce qui permet d'avoir une hauteur de massif relativement réduite laissant de grandes ouvertures sur le côté facilitant le montage des faisceaux 8 du condenseur 3.Note that the loads on the block 5 are strictly reduced to the mass of the BP module 2, which makes it possible to have a relatively reduced block height leaving large openings on the side facilitating the mounting of the bundles 8 of the condenser 3.

Le montage des faisceaux 8 est totalement indépendant de l'enceinte 4, ce qui facilite la maintenance et en particulier le changement complet de ceux-ci (voir figure 5).The assembly of the beams 8 is completely independent of the enclosure 4, which facilitates maintenance and in particular the complete change of these (see FIG. 5).

Les faisceaux 8 sont montés à libre dilatation dans des plaques tubulaires 17. Ces plaques 17 sont supportées par l'intermédiaire de plots élastiques 18 par des appuis internes 19 en béton disposés à l'intérieur de l'enceinte 4.The bundles 8 are mounted with free expansion in tubular plates 17. These plates 17 are supported by means of elastic studs 18 by internal supports 19 made of concrete placed inside the enclosure 4.

Les extrémités des faisceaux 8 sont montées à libre dilatation dans deux plaques d'extrémité 20. Les plaques 20 sont munies sur le pourtour d'un joint élastique 21 en forme de U assurant l'étanchéité avec l'enceinte 4.The ends of the bundles 8 are mounted with free expansion in two end plates 20. The plates 20 are provided on the periphery of an elastic seal 21 in the form of a U ensuring sealing with the enclosure 4.

Les plaques 17 et 20 sont reliées par des tirants horizontaux 22.The plates 17 and 20 are connected by horizontal tie rods 22.

Sur chacune des plaques d'extrémités 21 est fixée une boîte à eau 23 qui est munie de pattes 24. Les pattes 24 de l'une des boîtes 23 sont fixées et supportées par des appuis externes 19' en béton reposant sur le radier 9.On each of the end plates 21 is fixed a water box 23 which is provided with lugs 24. The lugs 24 of one of the boxes 23 are fixed and supported by external supports 19 ′ in concrete resting on the raft 9.

Les pattes 24 de l'autre boîte à eau sont en appui sur des appuis externes 19' en béton par l'intermédiaire de plots élastiques 18 permettant la dilatation des faisceaux 8.The legs 24 of the other water box are supported on external supports 19 ′ of concrete by means of elastic studs 18 allowing the beams 8 to expand.

Selon une variante de la figure 5 représentée à la figure 6, il n'y a pas d'appuis externes, mais on utilise pour porter les plaques 17 voisines des plaques 20 des supports en acier 25 fixés sur l'enveloppe interne de l'enceinte 4 (voir figure 6). Un seul des supports 25 est muni d'un plot élastique 18, l'autre sert de point fixe.According to a variant of FIG. 5 represented in FIG. 6, there are no external supports, but steel plates 25 fixed to the internal envelope of the plate are used to carry the plates 17 adjacent to the plates 20 enclosure 4 (see figure 6). Only one of the supports 25 is provided with an elastic pad 18, the other serves as a fixed point.
