Abstract

L'invention concerne un injecteur de combustible destiné à être utilisé dans un four, qui provoque le mélange d'un courant primaire d'un gaz porteur et de combustible avec de l'air chauffé, de l'oxygène ou un mélange d'oxygène et de CO2 ou d'un gaz de combustion en recirculation, à l'intérieur de l'injecteur, par un courant secondaire d'air chauffé, avant que le courant primaire ne sorte de l'injecteur en tant que courant de combustible et s'écoule dans une zone de combustion du four. L'interaction du courant primaire avec l'air chauffé du courant secondaire augmente la stœchiométrie au centre du courant de combustible sortant de l'injecteur, ce qui réduit le dégagement de NOx et augmente la combustion du combustible dans le four.
