Abstract

La présente invention se rapporte à un carburant obtenu par décomposition et recombinaison de l'eau et à une chambre de combustion mettant en oeuvre ce carburant. Ce carburant est composé d'un mélange de 20 à 70 % d'eau et de 30 à 80 % d'alcool ou de carbinol. La chambre de combustion est un baril doté d'un ventilateur, équipée d'une bobine de préchauffage. Une extrémité de la bobine est reliée à l'orifice d'admission du carburant du baril et l'autre extrémité est reliée à un orifice d'entrée de carburant d'un catalyseur. Un orifice de sortie du carburant du catalyseur est relié à un éjecteur fixé dans le baril ; le panneau du catalyseur à trous multiples est disposé au-dessus de l'ouverture du baril. Le carburant est préchauffé, catalysé, décomposé et sa combustion est assistée de manière à obtenir une combustion complète. Lorsque la chambre de combustion est placée à l'intérieur d'une entrée de carburant d'une chaudière ou d'un four de fusion, ladite chambre peut fonctionner avec ce carburant et du charbon, ce qui permet d'économiser le carburant fossile et de réduire la pollution environnementale. En cas de panne de la chambre de combustion, son remplacement par une chambre neuve et sa réparation n'ont pas d'incidence sur la production.
