Abstract
La présente invention concerne un brûleur de type à prémélange partiel dans lequel de l'hydrogène, un combustible exempt de carbone, est mélangé et brûlé dans un brûleur de chaudière à basse pression dédié au GNL et au gaz de ville classique, et qui, en tenant compte de la vitesse de combustion rapide de l'hydrogène, est pourvu d'une pluralité de buses de combustible pour former des flammes divisées, ce qui permet de supprimer la formation de polluants tels que des oxydes d'azote et d'empêcher un retour de flamme.
