CHAUDIERE A CHALEUR PERDUE.LOST HEAT BOILER.
Avec les coûts croissants de l'énergie, on consacre de plus en plus d'attention à l'énergie des gaz brûlés et a son utilisationv Pour cette raison, en a développé difégent types de chaudières å chaleur perdues Les chaudières sont construites, soit pour une circulation naturelle d'eaux soit pour une circulation forcée. Actuellement, par exemple, la plupart des navires utilisent des chaudières à chaleur perdue.With the increasing costs of energy, more and more attention is being devoted to the energy of burnt gases and to its use. For this reason, different types of waste heat boilers have been developed. Boilers are built either for a natural circulation of water is for a forced circulation. Currently, for example, most ships use waste heat boilers.
Les chaudières à chaleur perdue de l'art antérieur ont une construction à tubes de feu ou à tubes d'eau. Les chaudières à tubes d'eau sont souvent préférées, du fait de leur meilleur rapport surface de chauffe/poids. Les chaudières à chaleur perdue à tubes d'eau actuellement -utilisées comprennent à la fois des chaudières à tubes unis et des chaudières à tubes nervurés, destinés à faciliter le transfert de chaleur.The waste heat boilers of the prior art have a fire tube or water tube construction. Water tube boilers are often preferred because of their better heating surface to weight ratio. The currently used waste water tube boilers include both plain tube boilers and ribbed tube boilers, intended to facilitate heat transfer.
Les chaudières à chaleur perdue ont généralement, soit une forme rectangulaire, soit une forme cylindrique. Les chaudières à chaleur perdue munies de tubes unis sont en général cylindriques, du fait que la fabrication de tubes d'eau hélicoidaux est facile. La chaudière suivant l'invention est de préférence de ce type;
La commande d'une chaudière à chaleur perdue a présenté jusqu'ici des problèmes, du fait que les besoins en énergie thermique, par exemple à bord d'un bateau, varient considérablement. En outre, la quantité de gaz brûlés varie en fonction de la charge de la machine. Afin d'obtenir une fiabilité suffisante du fonctionnement à bord, les exigences relatives aux propriétés de la commande-ont été réduites dans les réalisations actuelles.La commande des chaudières à chaleur perdue dans les navires actuels est généralement conforme à l'un des types suivants - La chaudière est divisee en blocs dont une partie peut
être maintenue à sec quand on désire réduire la sortie de
la chaudière. Ce procédé a l'inconvénient que la commande
est progressive et que la dilatation thermique provoque
des contraintes dans la chaudière.Waste heat boilers generally have either a rectangular or a cylindrical shape. Waste heat boilers with plain tubes are generally cylindrical, since the manufacture of helical water tubes is easy. The boiler according to the invention is preferably of this type;
The control of a waste heat boiler has so far presented problems, since the thermal energy requirements, for example on board a boat, vary considerably. In addition, the amount of gas burned varies depending on the load of the machine. In order to obtain sufficient reliability of operation on board, the requirements relating to the properties of the control have been reduced in current embodiments. The control of waste heat boilers in current ships generally conforms to one of the following types - The boiler is divided into blocks, part of which can
be kept dry when you want to reduce the output of
Boiler. This process has the disadvantage that the command
is progressive and that thermal expansion causes
constraints in the boiler.
- Une variante consiste à décharger l'excès de puissance de
sortie à travers un échangeur de chaleur dans la mer. Ce
procédé est fiable mais coûteux, du fait de la capacité
d'echange thermique supplémentaire requise.- A variant consists in discharging the excess power from
outlet through a heat exchanger in the sea. This
process is reliable but expensive, due to the capacity
additional heat exchange required.
- On utilise la dérivation des gaz brûlés comme troisième
méthode de réglage de commande. En d'autres termes,
seulement une partie des gaz brûlés est alimentée dans la
chaudière à chaleur perdue.- We use the bypass of burnt gases as the third
control setting method. In other words,
only part of the burnt gases is supplied to the
waste heat boiler.
Le canal de dérivation d'une chaudière à chaleur perdue est généralement disposé à leextérieur de la chaudière et la plaque de réglage est réalisée en deux parties, l'une commandant le débit qui arrive à la chaudière et l'autre celui qui traverse le canal de dérivation. L'inconvénient d'un tel mécanisme est que les deux plaques peuvent être refermées simultanément, d'où il résulte que le canal des gaz brûlés est inutilisable.The bypass channel of a waste heat boiler is generally arranged outside the boiler and the adjustment plate is made in two parts, one controlling the flow rate which arrives at the boiler and the other one which crosses the channel bypass. The disadvantage of such a mechanism is that the two plates can be closed simultaneously, which results in the flue gas channel being unusable.
Un amortisseur de son est souvent placé dans le canal des gaz brûlés, après la chaudière à chaleur perdue et le canal de dérivation, ce qui garantit l'amortissement suffisant du son également pendant le fonctionnement de la chaudière. Ce système a l'inconvénient d'être couteux, de requérir un espace important et d'entre lourd dans sa construction, par suite du nombre des pièces qu'il met en oeuvre. A sound damper is often placed in the flue gas channel, after the waste heat boiler and the bypass channel, which guarantees sufficient sound damping also during the operation of the boiler. This system has the disadvantage of being expensive, of requiring a large and heavy space in its construction, due to the number of parts that it implements.
L'invention propose une chaudière à chaleur perdue plus simple et plus économique.The invention provides a simpler and more economical waste heat boiler.
La chaudière à chaleur perdue suivant l'invention comprend une section de convection contenant des tubes à eau hélicoldaux et est principalement caractérisée en ce que la section de convection a la forme d'un espace annulaire, qu'un canal de dérivation pour les gaz brûlés est formé dans le cylindre entouré par l'espace annulaire et que les parois du canal de dérivation sont garnies d'une matière absorbant le son, de façon que le canal de dérivation serve en même temps d'amortisseur du bruit.The waste heat boiler according to the invention comprises a convection section containing helical water tubes and is mainly characterized in that the convection section has the form of an annular space, as a bypass channel for the burnt gases is formed in the cylinder surrounded by the annular space and that the walls of the bypass channel are lined with a sound absorbing material, so that the bypass channel serves at the same time as noise damper.
En comparaison des chaudières à chaleur perdue et des amortisseurs de bruit connus, l'espace requis par la chaudière suivant l'invention est considérablement plus faible ; par exemple la hauteur requise pour l'ensemble est d'environ la moitié de celle requise par une chaudière et un amortisseur de bruit disposés l'un à la suite de l'autre. Comme le canal de dérivation et l'amortisseur de bruit sont à l'intérieur de la chaudière, on obtient une réduction de poids considérable. Le pare-étincelles sert de structure de support, ce qui réduit également la hauteur totale. Dans la chaudière suivant l'invention, une simple vanne papillon est utilisée comme plaque d'amortissement, ce qui procure un fonctionnement fiable avec de bonnes propriétés de régulation.Compared with waste heat boilers and known noise dampers, the space required by the boiler according to the invention is considerably lower; for example the height required for the assembly is approximately half that required by a boiler and a noise damper arranged one after the other. As the bypass channel and the noise damper are inside the boiler, a considerable weight reduction is achieved. The spark arrester serves as a support structure, which also reduces the overall height. In the boiler according to the invention, a simple butterfly valve is used as a damping plate, which provides reliable operation with good regulation properties.
L'invention sera mieux comprise à l'aide de la description ci-après, relative à un mode d'exécution préféré.The invention will be better understood with the aid of the description below, relating to a preferred embodiment.

Figure 2 is a top view of the boiler; and
Figure 3 is a longitudinal section.
A la figure 1, le numéro de référence 1 désigne la coque extérieure d'une chaudière ; les numéros 2 et 3, des ouvertures d'entrée et de sortie pour les gaz brûlés. Les moyens de distribution sont désignés par 4 et une valve de sécurité par 5. Les pattes d'attache de la chaudière sont désignées par 6 et une jauge de pression par 7. Le mécanisme d'entrainement d'une plaque de réglage de dérivation 12 est désigné par 8 et des portes servant à l'entretien sont désignées par 9 sur le sommet de la chaudière. Dans le cône inférieur de la chaudière est prévue une tubulure 10 par laquelle s'échappent l'eau de lavage de la chaudière et l'eau qui fuit de la section de convection.In Figure 1, the reference number 1 designates the outer shell of a boiler; numbers 2 and 3, inlet and outlet openings for burnt gases. The distribution means are designated by 4 and a safety valve by 5. The attachment tabs of the boiler are designated by 6 and a pressure gauge by 7. The drive mechanism of a bypass adjustment plate 12 is designated by 8 and maintenance doors are designated by 9 on the top of the boiler. In the lower cone of the boiler is provided a tube 10 through which escape the washing water from the boiler and the water which leaks from the convection section.
La section de convection 21 contenant les tubes d'eau héli cotidaux est représentée à la figure 3. Elle a une forme annulaire, d'où il résulte qu'un canal de dérivation des gaz brûlés 13 est formé dans le cylindre 22 entouré par la section 21. Le cylindre 22 est garni d'une matière 16 absorbant le bruit, par exemple de la laine de verre, par dessus laquelle une membrane de protection et une plaque d'acier perforée 14 sont disposées. Afin d'améliorer l'amortissement du bruit, un second cylindre 23, avec une matière absorbant le bruit 16 et des couvercles de protection 15, est disposé à l'intérieur du cylindre 22.The convection section 21 containing the heli cotidal water tubes is shown in FIG. 3. It has an annular shape, from which it follows that a flue gas bypass channel 13 is formed in the cylinder 22 surrounded by the section 21. The cylinder 22 is lined with a noise absorbing material 16, for example glass wool, over which a protective membrane and a perforated steel plate 14 are arranged. In order to improve noise absorption, a second cylinder 23, with a sound absorbing material 16 and protective covers 15, is placed inside the cylinder 22.
La plaque de réglage de dérivation ou volet 12 est montée dans un tube 20 relié à une extrémité supérieure de la plaque de réglage 13, d'où il résulte que l'axe de la plaque 12 est court et que les paliers peuvent être placés à l'extérieur de la chaudière.The bypass adjustment plate or flap 12 is mounted in a tube 20 connected to an upper end of the adjustment plate 13, from which it follows that the axis of the plate 12 is short and that the bearings can be placed at the outside of the boiler.
Des lames 17, situées à l'extrémité inférieure de la plaque 13, servent de pare-étincelles. Elles sont de préférence montées en structure de support pour le cylindre intérieur, soit directement, soit, conformément à la figure 3, par l'intermédiaire de la pièce de protection 15. Cette dernière est, dans la plupart des réalisations pratiques, suffisamment robuste pour servir au montage. En variante, les lames 17 peuvent être montées sur la pièce de protection 14 ou fixées au cylindre 22.Blades 17, located at the lower end of the plate 13, serve as a spark arrester. They are preferably mounted as a support structure for the inner cylinder, either directly or, in accordance with FIG. 3, by means of the protective part 15. The latter is, in most practical embodiments, sufficiently robust to serve for mounting. As a variant, the blades 17 can be mounted on the protective part 14 or fixed to the cylinder 22.
Un canal d'amenée de gaz brûlés 18 se termine devant le pare-étincelles 17 et a un diamètre plus petit que -l'amor- tisseur de bruit 13, si bien-qu'une connexion 19 est établie à partir du canal d'amenée 18, jusqu'à la section de convection 21.A flue gas supply channel 18 ends in front of the spark arrester 17 and has a smaller diameter than the noise damper 13, so that a connection 19 is established from the led 18, to convection section 21.
La chaudière décrite fonctionne de la manière suivante lorsque la plaque 12 est ouverte, les gaz brûlés passent du canal d'amenée, à travers le pare-étincelles 17, au canal combiné d'amortissement de bruit et de dérivation 13 et sont déchargés à travers l'orifice de sortie 3. Lorsque la plaque 12 est tournée vers la position de fermeture, la résistance de passage dans la dérivation 3 croît et une partie des gaz brûlés est défléchie à travers l'ouverture 19, vers la section de convection formée par les spires du tube 11.The boiler described operates in the following way when the plate 12 is open, the burnt gases pass from the supply channel, through the spark arrester 17, to the combined noise damping and bypass channel 13 and are discharged through the outlet orifice 3. When the plate 12 is turned towards the closed position, the resistance of passage in the bypass 3 increases and a part of the burnt gases is deflected through the opening 19, towards the convection section formed by the turns of the tube 11.
Lorsque la plaque 12 est en position fermée, la totalité des gaz brûlés passe à travers la section de convection. La taille de l'ouverture 19 entre l'amortisseur de bruit et le canal d'amenée est déterminée sur la base de la résistance du canal de gaz brûlés et des propriétés de la machine.When the plate 12 is in the closed position, all of the burnt gas passes through the convection section. The size of the opening 19 between the noise damper and the supply channel is determined on the basis of the resistance of the burnt gas channel and the properties of the machine.
L'ouverture 19 est aussi petite que possible, de manière que le débit aboutissant à la section de convection soit faible lorsque la dérivation est en position ouverte.The opening 19 is as small as possible, so that the flow rate leading to the convection section is low when the bypass is in the open position.
Même dans le cas où la plaque 12 est entièrement fermée, on réalise un amortissement très efficace du bruit, par suite des changements des directions de circula-tion du gaz dans la partie inférieure de la chaudière et de l'amortisseur de bruit.Even in the case where the plate 12 is fully closed, a very effective noise damping is carried out, as a result of changes in the directions of circulation of the gas in the lower part of the boiler and of the noise damper.
La partie supérieure de la chaudière est conformée de manière que la résistance de passage à la jonction du canal de dérivation et de la section de convection soit négative, ce qui empêche le passage de gaz brûlés dans le sens incorrect. Les impuretés qui s'accumulent à partir du pare-étincelles 17 et le dépôt qui est libéré quand on nettoie la chaudière, aussi bien que l'eau provenant d'une fuite quelconque, circulent vers le cône inférieur de la chaudière, d'où ils peuvent être enlevés à travers la tubulure 10.The upper part of the boiler is shaped so that the passage resistance at the junction of the bypass channel and the convection section is negative, which prevents the passage of burnt gases in the incorrect direction. The impurities which accumulate from the spark arrester 17 and the deposit which is released when the boiler is cleaned, as well as the water coming from any leak, circulate towards the lower cone of the boiler, from where they can be removed through tubing 10.
I1 est clair que les détails de réalisation du drspositif peuvent varier ; par exemple, le pare-étincelles 17 peut être d'un autre type : le cône intérieur 23 peut être omis de l'amortisseur de bruit 13 t ou le débit vers la section de convection peut être empêché par une plaque de réglage qui ferme le débit à la fois dans la dérivation et la section de convection. L'invention peut, bien entendu, s'appliquer également à une chaudière de forme rectangulaire ; ainsi, le concept d'espace annulaire n'est pas limité à un anneau circulaire. It is clear that the construction details of the device may vary; for example, the spark arrester 17 can be of another type: the internal cone 23 can be omitted from the noise damper 13 t or the flow to the convection section can be prevented by an adjustment plate which closes the flow in both the bypass and the convection section. The invention can, of course, also apply to a boiler of rectangular shape; thus, the concept of annular space is not limited to a circular ring.
