Description

Gazogene ä: ventilation foreee. Dans tout appareil de chauffage, et ä plus forte raison dans toute installation de chauffage avec gazogene, 1'adjonetion d'un dispositif de ventilation forcee augmente dans une tres largo mesure la securite de fonctionnement et 1e rendement. Gazogen ä: forced ventilation. In any heating appliance, and a fortiori in any gas-generated heating installation, the addition of a forced ventilation device greatly increases operational safety and efficiency.

Lobjet de la presente invention est un gazogene ä ventilation forcee. Il est earac- terise par un espace de distillation avec cou- vercle etanche, par un Foyer dispose au bas de cet espace de distillation et comprenant une grille inferieure d'evacuation des cendres et d'admission d'air Primaire, et une grille laterale de sortie des produits de distillation formant un cöte du Foyer oriente vors un orifiee de sortie du gaz, par au moins une tuyere de ventilation forcee disposee sous 1e Foyer et orientable, de faqon ä pouvoir four- nir une Proportion reglable ä, volonte d'air Primaire et d'air secondaire dirige vors le- dit orifice de sortie du gaz, et par un dis- positif reglable quantitativement assurant 1'alimentation d'air de la tuyere. The object of the present invention is a forced ventilation gasifier. It is characterized by a distillation space with an airtight lid, by a Hearth placed at the bottom of this distillation space and comprising a lower grid for ash removal and Primary air intake, and a side grid outlet of the distillation products forming one side of the Hearth oriented towards a gas outlet orifice, by at least one forced ventilation nozzle arranged under the Hearth and orientable, so as to be able to provide an adjustable Proportion at, will of Primary air and secondary air is directed to said gas outlet orifice, and by a quantitatively adjustable device ensuring the air supply to the nozzle.

Le dessin ei-annexe represente, ä titre d'exemple, une forme d'execution du gazo- g6ne faisant 1'objet de 1'invention. The attached drawing shows, by way of example, one form of execution of the gazogene which is the subject of the invention.

Les fig. 1 et 2 en sont deux coupes ver- ticales selon deux Plans perpendiculaires 1'un ä 1'autre. La fig. 3 en est une coupe horizontale. Figs. 1 and 2 are two vertical sections of it along two mutually perpendicular planes. fig. 3 is a horizontal section.

Dans la forme d'execution representee, 1'espace de distillation 1 a une section hori zontale earree. Il est entoure de briques re- fractaires 2, dune couche d'amiante 3" et dune enveloppe metallique 4. In the embodiment shown, the distillation space 1 has a square horizontal section. It is surrounded by refractory bricks 2, a layer of asbestos 3" and a metal casing 4.

Le couvercle 5 presente un espace d'air et une Plaque d'amiante 6 avec revetement interieur metallique 7, qui forme joint etan- che avec 1e Bord superieur de 1'espace 'de distillation 1. Le couverele Porte des char- ni6res 8, une Barre transversale 9 pivotant en son point milieu et engageant par ses extremites des erochets 10, et un bouton cen- tral 11 de serrage. The cover 5 has an air space and an asbestos plate 6 with metallic lining 7, which forms a tight seal with the upper edge of the distillation space 1. The cover carries hinges 8, a transverse bar 9 pivoting at its midpoint and engaging hooks 10 at its ends, and a central tightening knob 11.

Dans sa Partie inferieure, 1'espace de dis- tillation 1 presente un foyer 12 comprenant une grille inferieure 13 et une grille laterale oblique 14 formant un cöte du Foyer oriente In its lower part, the distillation space 1 has a hearth 12 comprising a lower grid 13 and an oblique side grid 14 forming one side of the hearth oriented

vers un orifice 1.5 de sortie du gaz. Ces deux grillen sont construites avee des bar reaux en fer 16 as:enibles de maniere inter changeable au moyen de houlons 17 et d'en tretoises 18. to a gas outlet port 1.5. These two grills are constructed with iron bars 16 which are interchangeable by means of bolts 17 and spacers 18.

U ne Porte d'allumage etanehe 19 est amenagee ä 1a base du fover et une Porte de cendrier 20 est disposee au-dessotts du niveatt des grillen. 1Tne tu yere 21 est Placee sous 1e foyer, du cöte oppose ä Forifice 15 de sortie du gaz. Cet;te tuyere est montee de fagon pivotante, au moyen d'un filetage 22, nur une conduite d'amenee d'air 23 reliee ii un ventilateur electrique ?4. La tuyere Porte une tige ? 5 munie d'un bouton e xterieur de commande 26 permettanl: de modifier Fangle d'incidence de Fair sous la grille. A sealed ignition door 19 is provided at the base of the stove and an ashtray door 20 is disposed below the level of the grills. 1Tne tu yere 21 is placed under the hearth, on the opposite side to the gas outlet orifice 15. This; you nozzle is pivotally mounted, by means of a thread 22, nur an air supply pipe 23 connected ii an electric fan? 4. The nozzle carries a rod? 5 provided with an external control button 26 permettanl: to modify the angle of incidence of Fair under the grid.

Le ventilateur presente un orifiee d'as piration ? 7 contre leqttel vient se placer un obturateur 28 eommand'e par un levier 29 avee manette 30. Does the fan have a suction port? 7 against leqttel is placed a shutter 28 eommand'e by a lever 29 with handle 30.

Le fonctionnement du gazogeiie repre sent'e est 1e suivant: 0n remplit 1'espace 1 de combttsti.ble, par exemple de bizchettes de bois, et an allume par la Porte d'allumabe. Pendant la Periode de laneement, la tuyere est dirigee vers 1e haut, en tournant 1e bouton ?6 dann 1e sens inverse des aiguilles dune montre, afin de donner prineipalement de Fair Primaire (p), et 1a. manette de commande all du (lel)it du ventilateur est placee nu maximiun. La mise en service est ainsi tres rapide. The operation of the gazogeiie repre sent'e is the following first: 0n fills 1'espace 1 of combttsti.ble, for example of bizchettes of wood, and year lights by the Door of allumabe. During the Start Period, the nozzle is directed upwards, by turning knob ?6 counter-clockwise, to give mainly Fair Primary (p), and 1a. Fan (lel)it all control handle is placed at maximum position. Commissioning is therefore very quick.

En manche normale, an regle 1e bouton 26 de la ttiyere selon la richesse de gaz que Von veut obtenir. Plus la Proportion d'air Primaire (p) est Brande, lorsqii'on oriente la tuyere vers le haut, plus le gaz est riehe, et plus la Proportion d'air secondaire (s) augmente, lorsque Fon abaisse la tuy ere, plus 1e gaz devient pauv re. In a normal handle, an adjusts the first button 26 of the valve according to the richness of gas that Von wants to obtain. The higher the Proportion of Primary air (p) is when the nozzle is oriented upwards, the richer the gas, and the more the Proportion of secondary air (s) increases, when the Fon lowers the nozzle, the more the gas becomes lean.

0n regle, en outre, ha nianette 30 du ven tilateur selon 1e dAit de chaleur ä fournir. En regime fa.ible, de nuit par exemple, il suffit Mime d'arreter 1e ventilateur et d'ou vrir la manette selon 1e de gre de tirage de Pinstallation, de fason ä maintenir 1e gazo gene pret ä etre remis en manche normale, simplement par enclenchement du ventila- teur. In addition, ha nianette 30 of the fan is regulated according to the heat demand to be supplied. In weak mode, at night for example, it is enough to stop the fan and to open the lever according to the first draft of the installation, so as to keep the gas ready to be put back in normal mode, simply by switching on the fan.

En cri d'interruption momentanee du courant electrique, 1e gazogene fonetionne avec ventilation naturelle en ouvrant la Porte du cendrier. In a cry of momentary interruption of the electrical current, the gasifier operates with natural ventilation by opening the door of the ash pan.

Dann une autre forme d'execution, la t:ityere pourrait etre alimentee par un ejecteur d'a,ir il vapeur reglable. Dann another form of execution, the t: ityere could be fed by an ejector of a, ir he adjustable vapor.

La forme d'execution representee est plus particulierement destinee ä fonctionner au bois dann une installation fixe. D'autres formen d'execution de 1'objet de 1'invention pourront etre adaptees ä d'autres combusti- Wes et ii des installations mobiles. The embodiment represented is more particularly intended to operate on wood in a fixed installation. Other embodiments of the object of the invention may be adapted to other fuels and to mobile installations.

lies avantages principaux du gazogene repi-esente sont sa simplicite de construction et de manipulation et son bon fonetionne- inent il tous les regimes. The main advantages of the representative gasifier are its simplicity of construction and handling and its good functioning, making it suitable for all regimes.
