Abstract

La présente invention concerne un injecteur de combustible (10) conçu pour être utilisé dans un four. Cet injecteur de combustible (10) est utilisé pour fournir du combustible pulvérisé à une chambre de combustion d'un four. La structure de l'injecteur de combustible (10) permet une combustion efficace et, dans un même temps, elle permet de stabiliser la flamme de combustion. Ainsi, une quantité minime de NOX et d'autres produits dérivés non souhaitables est libérée dans l'atmosphère.
