Abstract

The device has a combustion chamber (1), for receiving a fuel, connected to a post combustion chamber (7) through a combustion reactor (2). The reactor is provided with an air inlet (5) and a passage (3) for mixing the fuel and an oxidant e.g. air. The post combustion chamber has a post combustion gas evacuated through an evacuation tube (4) concentric to a tube of the combustion reactor.

Description

La présente invention concerne un réacteur de combustion et deThe present invention relates to a combustion and

postcombustion permettant d'échauffer le comburant par léchage du tube d'échappement des gaz, tube concentrique au réacteur de combustion (2).  afterburner for heating the oxidant by licking the gas exhaust tube, concentric tube to the combustion reactor (2).

Ce dispositif permet aussi de faire passer les gaz de postcombustion par le tube d'évacuation lui-même soumit extérieurement à la chaleur de la combustion primaire.  This device also makes it possible to pass the afterburner gases through the evacuation tube itself subjected externally to the heat of the primary combustion.

Les gaz pauvres produits dans la chambre de combustion (1) peuvent soit être réintroduits dans le réacteur de combustion primaire(2), soit être récupérés pour une autre utilisation.  The poor gases produced in the combustion chamber (1) can either be reintroduced into the primary combustion reactor (2) or be recovered for another use.

Selon les modes particuliers de réalisation, La chambre de combustion primaire (1) recevant le combustible (11) peut être cylindrique, carré, conique ou ovale, rectangulaire ou parallélépipédique. Elle est reliée à la chambre de postcombustion (7) par le réacteur primaire(2) le réacteur primaire (2) peut être cylindrique, carré, conique tronqué , ovale, rectanglulaire ou parallélépipédique.  According to the particular embodiments, the primary combustion chamber (1) receiving the fuel (11) may be cylindrical, square, conical or oval, rectangular or parallelepiped. It is connected to the afterburner (7) by the primary reactor (2) the primary reactor (2) can be cylindrical, square, conical truncated, oval, rectangular or parallelepiped.

le réacteur primaire (2)est percé de n'importe quel dessin géométrique rond, ovale, rectangle,carré, parallélépipède, lumières (3) permettant le contact du combustible (11) et du comburant.(air).  the primary reactor (2) is pierced with any round, oval, rectangle, square, parallelepiped geometrical design, lights (3) allowing the contact of the fuel (11) and the oxidant (air).

Le tube d'évacuation des gaz (4), concentrique au tube du réacteur primaire (2) peut être cylindrique, carré, conique tronqué, ovale, rectangle ou parallépipédique.  The gas evacuation tube (4), concentric with the tube of the primary reactor (2) may be cylindrical, square, conical truncated, oval, rectangle or parallelepiped.

L'aspiration (9) des gaz brulés (12) peut-être effectuée par l'effet venturi ou par un système d'aspiration traditionnel type ventilateur. Une fois la combustion lancée, il peut devenir autonome par effet de cheminée.  The extraction (9) of the burned gases (12) can be carried out by the venturi effect or by a traditional fan-type suction system. Once the combustion is launched, it can become autonomous by chimney effect.

Principe de fonctionnement On met en route l'effet d'aspiration (9) des gaz brulés (12) Le combustible (11) est introduit dans la chambre de combustion (1) Au démarrage, il est enflammé par un apport extérieur de feu réalisé soit par un brûleur gaz, mazout ou autre énergie (10), flamme introduite dans une entrée d'air (5) du réacteur primaire, soit directement dans la chambre de combustion (1) tel que l'on allume un feu de bois.  Principle of operation The suction effect (9) of the burnt gases (12) is started. The fuel (11) is introduced into the combustion chamber (1). At the start, it is ignited by an external contribution of fire. or by a burner gas, fuel oil or other energy (10), flame introduced into an air inlet (5) of the primary reactor, or directly into the combustion chamber (1) such as a wood fire is lit.

Par dépression dans la chambre de postcombustion(1) , le comburant (air) est aspiré au travers de lumières d'admission (5) du réacteur primaire ((2) et vient au contact du combustible (11) au travers des lumières (3) éffectuées autour du réacteur primaire (2). Les flammes et les gaz de combustion (8) arrivent dans la chambre de postcombustion (7).  By depression in the afterburner (1), the oxidizer (air) is sucked through intake ports (5) of the primary reactor ((2) and comes into contact with the fuel (11) through the lights (3). ) flames and combustion gases (8) arrive in the afterburner (7).

La réaction de combustion se produit au travers des lumières(3) et s'effectue autour du tube d'évacuation (4) des gaz de postcombustion.  The combustion reaction takes place through the lumens (3) and takes place around the exhaust tube (4) of the afterburning gases.

La combustion participe au chauffage du tube d'évacuation (4)des gaz.  The combustion contributes to the heating of the evacuation tube (4) of the gases.

Le tube d'évacuation des gaz (4)monté en température,et passant à l'intérieur du tube réacteur primaire (2) réchauffe à l'entrée du réacteur primaire (2) le comburant (air) rentrant par les lumières d'admission (5) La combustion est améliorée par le réchauffement du comburant (air) Les gaz de postcombustion(12) sont mieux brûlés car il passent dans le tube d'évacuation (4) monté au rouge lors de la traversée du réacteur primaire (2).  The temperature-evacuated gas evacuation tube (4), passing inside the primary reactor tube (2), heats the oxidizer (air) entering through the intake ports at the inlet of the primary reactor (2). (5) The combustion is improved by the heating of the oxidizer (air) The afterburning gases (12) are better burned because they pass through the evacuation tube (4) mounted red when crossing the primary reactor (2) .

Réglage de la combustion Les lumières (3) présentent sur le tube réacteur primaire (2) peuvent être plus ou moins obturées pour augmenter ou réduire la quantité de combustible(11) mise au contact du comburant (air).  Adjusting the combustion The lights (3) on the primary reactor tube (2) can be more or less closed to increase or reduce the amount of fuel (11) brought into contact with the oxidizer (air).

Les lumières d'entrée d'air (5) au début du tube réacteur primaire peuvent être plus ou moins obturées pour augmenter ou réduire la quantité de comburant (air) introduite dans le tube réacteur primaire(2).  The air inlet ports (5) at the beginning of the primary reactor tube may be more or less closed to increase or reduce the amount of oxidant (air) introduced into the primary reactor tube (2).

Le réglage de la puissance d'aspiration des gaz de postcombustion (12) accélère ou ralenti la combustion.  Adjusting the suction power of the afterburner gases (12) accelerates or slows the combustion.

Une ou plusieures entrées d'air réglables (6) peuvent être réalisées sur la fin du tube réacteur primaire (2) pour aider à la postcombustion.  One or more adjustable air inlets (6) may be provided on the end of the primary reactor tube (2) to assist in afterburning.

La chambre de postcombustion (7) acueille jointivement étanche le tube du réacteur primaire (2) L'installation fonctionne en position horizontale, verticale ou oblique, la seule nécessité étant de changer le positionnement du chargement de la chambre de combustion (1)  The afterburner chamber (7) receives tightly sealed the tube of the primary reactor (2) The installation operates in horizontal, vertical or oblique position, the only need being to change the positioning of the loading of the combustion chamber (1)
