Abstract

The device for recovering heat from the exhaust gases and smoke from a steam boiler heated by fuel or gas, having, in the space between its inner and outer concentric walls as well as above the dome closing the inner wall, a water reserve into which a flue (smoke pipe) connected to the discharge chimney is immersed, is composed of a cylindrical jacket (15) surrounding the external wall 1 of the boiler in line with the nozzles 8 of the boiler and forming, with the latter, an annular volume 21 connected via a pipe 18 to the pipe 14 for exhausting the gases from the burners 10 and to the gas-outlet chimney 19, a vertical baffle 17 being disposed in the volume 21 at the inlet of the pipe 18 in order to direct the gas flow into the jacket 15 up to discharge.

Description

La présente invention a pour but la récupération des calories perdues dans la cheminée d'évacuation des gaz et fumées d'une chaudière, et particulièrement d'une chaudière du type de celle ayant fait l'objet du Brevet Français No 1402103 au nom de Monsieur Albert CERRUTI. The aim of the present invention is to recover the calories lost in the gas and smoke evacuation chimney of a boiler, and in particular of a boiler of the type which has been the subject of French Patent No 1402103 in the name of Monsieur Albert CERRUTI.

Cette chaudière présente dans l'espace compris entre ses parois concentriques intérieure et extérieure ainsi qu'au dessus du dôme fermant la paroi intérieure, une réserve d'eau dans laquelle est immergé un conduit de fumée relié à la cheminée d'évacuation. This boiler has in the space between its inner and outer concentric walls and above the dome closing the inner wall, a water reserve in which is immersed a flue connected to the exhaust chimney.

Afin de récupérer les calories perdues par la cheminée, la présente invention a pour objet un circuit supplémentaire chicané constitué par une chemise extérieure ceinturant le corps de la chaudière, reliée d'une part au conduit de sortie des gaz et d'autre part à la cheminée d'évacuation. In order to recover the calories lost by the chimney, the present invention relates to an additional baffled circuit constituted by an outer jacket encircling the body of the boiler, connected on the one hand to the gas outlet duct and on the other hand to the exhaust chimney.

Cette chemise appliquée sur la paroi externe de la chaudière, fait suite au conduit d'évacuation des gaz qu'elle dirige, par une chicane, dans toute sa périphérie, constituant une importante surface d'échange de la chaleur des gaz et fumées avec la surface extérieure du voile annulaire d'eau formant l'enveloppe de la chaudière. L'extrémité de cette chemise est reliée à la cheminée d'évacuation des gaz et fumées qui ont alors cédé la plus grande partie de leurs calories. This jacket applied to the external wall of the boiler, follows the gas evacuation duct which it directs, through a baffle, throughout its periphery, constituting a large heat exchange surface for the gases and fumes with the outer surface of the annular veil of water forming the envelope of the boiler. The end of this shirt is connected to the flue gas and smoke evacuation which then gave up most of their calories.

On décrira plus en détail ci-après, un exemple de réalisation du dispositif suivant l'invention, en référence au dessin annexé sur lequel
la figure 1 est une vue en coupe verticale suivant un plan diamétral de la chaudière. An embodiment of the device according to the invention will be described in more detail below, with reference to the attached drawing in which
Figure 1 is a vertical sectional view along a diametrical plane of the boiler.

La figure 2 est une vue en coupe transversale suivant II-II de la figure 1. FIG. 2 is a cross-sectional view along II-II of FIG. 1.

La chaudière représentée est du type de celle décrite dens le Brevet FR N & 1402103 : elle comporte une paroi extérieure 1 fermée à sa partie supérieure par un dôme 2 et une paroi intérieure 3 fermée à sa partie supérieure par un dôme 4, entre et au-dessus desquelles est constituée une capacité 5 étanche remplie d'eau. Les gaz chauds s'échappent dans le sens des flèches par un conduit 14 versune cheminée d'évacuation. The boiler shown is of the type described in patent FR N & 1402103: it has an outer wall 1 closed at its upper part by a dome 2 and an inner wall 3 closed at its upper part by a dome 4, between and at above which is a sealed capacity 5 filled with water. The hot gases escape in the direction of the arrows through a pipe 14 to an exhaust chimney.

Pour récupérer les calories de ces gaz, l'invention prévoit de ceinturer la chaudière au droit des tubulures 8 par une chemise cylindrique étanche 15 appliquée sur la paroi 1 par tous moyens convenables 16 et présentant une chicane verticale 17 près du raccord 18 de cette chemise annulaire 15 avec le conduit d'échappement 14, de manière à diriger les gaz chauds dans le sens de la flèche F sur toute la périphérie de l'espace 21 fermé entre la chemise 15 et la paroi 1 de la chaudière. To recover the calories from these gases, the invention provides for encircling the boiler in line with the pipes 8 by a tight cylindrical jacket 15 applied to the wall 1 by any suitable means 16 and having a vertical baffle 17 near the connector 18 of this jacket annular 15 with the exhaust duct 14, so as to direct the hot gases in the direction of arrow F over the entire periphery of the space 21 closed between the jacket 15 and the wall 1 of the boiler.

En bout de cet espace, les gaz s'échappent par un conduit 19 dans la cheminée d'évacuation 20. At the end of this space, the gases escape through a pipe 19 into the exhaust chimney 20.

On récupère ainsi à peu de frais une grande partie des calories des gaz et fumées de la chaudière, augmentant d'autant son rendement. A large proportion of the calories from the gases and fumes from the boiler are thus recovered inexpensively, thereby increasing its efficiency.

Des modifications pourront être apportées à cette réalisation suivant la nature de la chaudière, telles qu'accélérateur de tirage et addition de chicanes de turbulence.et trappes de nettoyage.  Modifications may be made to this embodiment depending on the nature of the boiler, such as draft accelerator and addition of turbulence baffles. And cleaning hatches.
