Abstract

The steam distributor is automatic and controls the temperature of a pipe in a gas producer plant. The pipe is cooled by circulation of water from a tank. The pipe carrying cooling water (2) is connected by two other pipes (4,5) to a closed water tank (6). The pipe tappings are placed below the water level and the steam carrying pipe (7) passes between a free space in the water tank, above the water level, and the entry (2) of combustion air into the producer itself (1).

Description

L'invention concerne un distributeur de vapeur d'eau autorégulateur de la température d'une tuyère de gazogène, la tuyère étant du type à refroidissement d'eau. The invention relates to a water vapor distributor self-regulating the temperature of a gasifier nozzle, the nozzle being of the water cooling type.

Un gazogène a pour but de transformer un combustible solide, par exemple du charbon de bois, en un gaz combustible formé d'oxyde de carbone et d'azote. Seul l'oxyde de carbone est intéressent pour l'alimentation d'un moteur à explosion, aussi le pouvoir calorifique du gaz n'est que de 5000kJ environ au m). Toutefois le charbon de bois contrent toujours une proportion plis ou moins importante d'eau qui est décomposée pour donner avec le carbone de l'oxyde de carbone et de l'hydrogène (ou gaz à l'eau"). L'hydrogène a un pouvoir calorifique d'environ le double de celui de l'-oxyde de carbone. The purpose of a gasifier is to transform a solid fuel, for example charcoal, into a combustible gas formed of carbon monoxide and nitrogen. Only carbon monoxide is of interest for the supply of an internal combustion engine, so the calorific value of the gas is only about 5000kJ per m). However charcoal always counteracts a fold or less proportion of water which is decomposed to give with carbon carbon monoxide and hydrogen (or gas with water "). Hydrogen has a calorific value about twice that of carbon monoxide.

L'augmentation du pouvoir calorifique du gaz de gazogène en favorisant la production de gaz à l'eau n1a pas échappe aux thermiciens qui ont tente artificiellement de favoriser cette réaction. Mais la vaporisation et la décomposition de l'eau est fortement endothermique et refroidit, à partir d'uRe certaine quantité, la zone de réduction dont la température n'est plus suffisante pour assurer la réduction principale de l'anhydride carbonique (C02) en oxyde de carbone (CO). The increase in the calorific value of the gasifier gas by promoting the production of gas in water has not escaped the thermicians who tried artificially to promote this reaction. But the vaporization and decomposition of water is highly endothermic and cools, from a certain quantity, the reduction zone whose temperature is no longer sufficient to ensure the main reduction of carbon dioxide (C02) in carbon monoxide (CO).

On peut remédier à cet état de choses en apportant une source de chaleur extérieure mais cette solution n'est applicable qu'à des gazogènes fixes. This state of affairs can be remedied by providing an external heat source, but this solution is only applicable to fixed gas generators.

le système GAZOTSP, décrit p 32 dans l'ouvrage "Le
Retour des Gazogènes" de Guy BARTHELEMY , Editions Alternatives comportait deux tuyères : une tuyère de ralenti par laquelle arrivait l'air extérieur et une tuyère de marche normale qui admettait dans le foyer de l'air et de la vapeur d'eau. L'eau était fournie par un carburateur et l'émulsion air-eau se vaporisait en passant dans une chemise entourant la tuyère qu'elle refroidissait. Un dispositif permettait d'arrêter l'arrivée d'air par la buse normale lorsque le moteur était au ralenti.the GAZOTSP system, described on p 32 in the book "The
Return of the Gasogens "by Guy BARTHELEMY, Editions Alternatives included two nozzles: an idle nozzle through which the outside air arrived and a normal walking nozzle which admitted air and water vapor into the hearth. water was supplied by a carburetor and the air-water emulsion vaporized by passing in a jacket surrounding the nozzle which it cooled. A device made it possible to stop the air supply by the normal nozzle when the engine was idling .

La quantité d'eau introduite par le système GAZOMAP est réglée d'une manière définitive et ne peut s'adapter aux conditions de fonctionnement du foyer, et en particulier à sa température, d'où il peut résulter une marche capricieuse du gazogène. The quantity of water introduced by the GAZOMAP system is definitively adjusted and cannot be adapted to the operating conditions of the fireplace, and in particular to its temperature, from which it may result in a capricious march of the gasifier.

Il ne semble pas que l'introduction d'eau dans l'air d'alimentation du foyer ait eu un large développement.  It does not seem that the introduction of water into the supply air of the household had a wide development.

L'invention vise à fournir un eistributeur de vapeur d'cau autorégulateur de la température d'une tuyère de gazogène, le refroidissement de la tuyère par circulation d'eau servant à générer de la vapeur d'eau Qui est introduite à l'entrée de la tuyère dans ltair de combustion. The invention aims to provide a steam distributor of water which self-regulates the temperature of a gasifier nozzle, the cooling of the nozzle by circulation of water serving to generate water vapor which is introduced at the inlet. of the nozzle in the combustion air.

Les explications et la figure données ci-après à titre d'exemple permettront de comprendre comment l'invention peut entre réalisée. The explanations and the figure given below by way of example will make it possible to understand how the invention can be achieved.

La figure unique montre schématiquement le distributeur de vapeur d'eau selon un exemple de réalisation de l'invention. The single figure shows schematically the steam distributor according to an exemplary embodiment of the invention.

Un gazogène se compose essentiellement d'une cuve 1 dans laquelle est introduit le combustible solide, par exemple du charbon de bois, d'une tuyère 2 par laquelle est introduit l'air de combustion. Un cendrier 3 est généralement prévu dans le fond de la cuve pour récupérer les cendres.On distingue dans la partie basse de la cuve deux zones particulièrement impòrtantes pour l'obtention du gaz
-la zone de combustion À où se produit une quantité limitée d'anhydride carbonique C02 obtenu par combustion des particules de charbon en contact avec l'air introduit par la tuyère et dont la température est de l'ordre de 1100 à 150000
-la zone de réduction 3, entourant la zone de combustion
A et dans laquelle le charbon ne peut pas briller car l'oxygène disponible a été entièrement utilisé dans la zone de combustion.A gasifier essentially consists of a tank 1 into which the solid fuel, for example charcoal, is introduced, a nozzle 2 through which the combustion air is introduced. An ashtray 3 is generally provided at the bottom of the tank to collect the ashes. There are two particularly important areas in the lower part of the tank for obtaining gas.
-the combustion zone At which a limited amount of carbon dioxide C02 is produced, obtained by combustion of the carbon particles in contact with the air introduced by the nozzle and whose temperature is of the order of 1100 to 150,000
-the reduction zone 3, surrounding the combustion zone
A and in which the coal cannot shine because the available oxygen has been fully used in the combustion zone.

le charbon au voisinage ou en contact avec la zone de combustion est porté à une température de 800 à 10000 C et réduit le C02 à l'état de CO.the coal in the vicinity or in contact with the combustion zone is brought to a temperature of 800 to 10,000 C and reduces the C02 to the CO state.

Lorsque l'on introduit de la vapeur d'eau, la réaction du carbone sur l'eau se fait avec une absorption de la chaleur qui s'ajoute à celle résultant de la réduction du 002 en C0. When water vapor is introduced, the reaction of carbon on water takes place with an absorption of heat which is added to that resulting from the reduction of 002 to C0.

Il y a donc une quantité d'eau à ne pas ddpasser sous peine de refroidir la zone de réduction et d'empocher la réduction du 002o
La dissociation de la vapeur d'eau commence à 8000 et devient intense à 10000 C donc dans une plage de température correspondant à celle de la zone de réduction. Il faut par conséquent maintenir la zone de réduction dans une plage de température relativement étroite (900 à 11000), compte tenu de la simplicité du réglage d'admission de l'air de combustion.There is therefore a quantity of water not to be exceeded under penalty of cooling the reduction zone and pocket the reduction of 002o
The dissociation of water vapor begins at 8000 and becomes intense at 10000 C therefore in a temperature range corresponding to that of the reduction zone. It is therefore necessary to maintain the reduction zone in a relatively narrow temperature range (900 to 11000), taking into account the simplicity of the adjustment of the combustion air intake.

L'introduction contrôlée de vapeur d'eau permet donc d'envisager outre une amélioration du pouvoir calorifique du gaz, une régulation efficace de la température de la tuyère elle-meme et du foyer,
Comme il est nécessaire de refroidir la tuyère pour lui assurer une durée de vie suffisante et que la température de In tuyère est fonction de la température des zones de combustion et de réduction, le refroidissement d-e la tuyère est utilisé pour produire de la vapeur qui est injectée à l'entrée de la tuyère.The controlled introduction of water vapor therefore makes it possible to envisage, in addition to an improvement in the calorific power of the gas, an effective regulation of the temperature of the nozzle itself and of the hearth,
As it is necessary to cool the nozzle to assure it a sufficient lifespan and that the temperature of the nozzle is a function of the temperature of the combustion and reduction zones, cooling of the nozzle is used to produce steam which is injected at the inlet of the nozzle.

La tuyère 2 comporte une cher1ise ou des canaux de refroidissement qui est ou sont alimentés par les tuyaux 4,5 a partir d'un réservoir fermé 6 contenant de l'eau. Le niveau d'eau est prévu au-dessus des piquages des tuyaux de manière à obtenir une circulation par thermosiphon. The nozzle 2 comprises a cher1ise or cooling channels which is or are supplied by the pipes 4,5 from a closed tank 6 containing water. The water level is provided above the pipe fittings so as to obtain circulation by thermosiphon.

Un choix judicieux des dimensions de la tuyère et de sa chemise d'eau permet de provoquer l'évaporation d'une quantité d'eau voulue dans une plage de température voulue. A judicious choice of the dimensions of the nozzle and its water jacket makes it possible to cause the evaporation of a desired quantity of water within a desired temperature range.

Cette évaporation permet la protection thermique de la tuyère par deux processus différents : refroidissement de la paroi de la tuyère par convection et évaporation de l'eau et refroidis de la température du foyer par introduction de vapeur d'eau.This evaporation allows the thermal protection of the nozzle by two different processes: cooling of the wall of the nozzle by convection and evaporation of the water and cooling of the temperature of the hearth by introduction of water vapor.

L'introduction darus le foyer de la vapeur d'eau produite par le refroidissement de la tuyère a pour effet de produire de l'hydrogène et donc d'augmenter le pouvoir calorifique dudu ga de gazogène.The introduction of the hearth of water vapor produced by the cooling of the nozzle has the effect of producing hydrogen and therefore increasing the calorific value of the gas generator.

On obtient donc une régulation de la température de la tuyère et du foyer sans perte d'énergie. A temperature regulation of the nozzle and of the hearth is therefore obtained without loss of energy.

A cet effet, l'élévation de température du foyer provoque un échauffement proportionnel de la tuyère et à partir d'une certaine limite, l'évaporation de l'eau circulant a travers le réservoir 6, le tuyau 4, la tuyère 2 le tuyau 5. For this purpose, the increase in temperature of the hearth causes a proportional heating of the nozzle and from a certain limit, the evaporation of the water circulating through the tank 6, the pipe 4, the nozzle 2 the pipe 5.

La vapeur, s'échappant dans l'espace libre du réservoir audessus de l'eau, est injectée par un tube d'amenée de vapeur 7 à l'entrée de la tuyère 2.The steam, escaping in the free space of the tank above the water, is injected by a steam supply tube 7 at the inlet of the nozzle 2.

Il est bien en entendu que la réalisation du dispositif n'est pas limitée à l'exemple décrit : mais que les éléments peuvent être rempTaces par des éléments ou dispositifs équivalents.  It is clearly understood that the production of the device is not limited to the example described: but that the elements can be replaced by equivalent elements or devices.
