Abstract

Cette invention se rapporte à un procédé améliorant la combustion, qui est capable d'améliorer efficacement les rendements des carburants à base de pétrole, ainsi qu'à un dispositif prévu à cet effet. Dans un procédé de combustion faisant l'objet de cette invention, qui utilise des carburants à base de pétrole, tels que l'essence, l'huile légère et l'huile lourde, le carburant fourni par le réservoir de carburant à la chambre de combustion est chauffé à des températures comprises dans une plage préétablie et acheminé dans la chambre de combustion dans un état partiellement vaporisé. Le rendement s'accroît généralement avec une augmentation de la température de chauffage, et une température à laquelle au moins une partie du carburant se vaporise est préférable, bien qu'une température de chauffage de l'ordre de 30 °C produit un certain gain. N'importe quelle source chauffante peut être utilisée comme moyen de chauffage, et, dans le cas des moteurs plus spécifiquement, le reflux de carburant allant de la chambre de combustion au réservoir de carburant est directement mis en circulation dans un conduit d'amenée de carburant et, dans le cas des chaudières et des brûleurs à huile lourde, un conduit d'amenée de carburant traverse une voie d'écoulement pour la vapeur de la chaudière ou alors traverse ou avoisine le combustible enflammé dans la chambre de combustion, de sorte qu'un excellent effet peut être obtenu avec de simples modifications des installations existantes.
