Abstract: L'invention concerne un four de gazéification ayant un agencement de brûleur en spirale double, se rapportant au domaine technique de la gazéification du charbon. Le four de gazéification comprend un corps de four de gazéification et plusieurs premiers brûleurs et plusieurs seconds brûleurs disposés sur la paroi interne d'un foyer du four de gazéification dans des lignes en spirale avec la même direction de rotation ; les orifices de brûleur des premiers brûleurs et des seconds brûleurs sont tous orientés vers le centre du foyer du four de gazéification ; sur le même plan horizontal dans le foyer, un second brûleur présente une symétrie centrale à chaque premier brûleur autour du centre du four ; les premiers brûleurs et les seconds brûleurs s'infléchissent de façon oblique vers le haut en direction de la paroi interne du foyer du four de gazéification selon le même angle ; et les directions de déviation des premiers brûleurs et des seconds brûleurs sont les mêmes que les directions de rotation des lignes en spirale sur lesquelles les premiers brûleurs et les seconds brûleurs sont agencés respectivement. La forme d'agencement multidimensionnel à double spirale des premiers brûleurs et des seconds brûleurs amène le charbon pulvérisé gazéifié à former des cyclones doubles diffusés vers l'extérieur et favorisés mutuellement, de telle sorte que la température centrale du four de gazéification est réduite, et des particules de cendres sont diffusées dans la direction radiale, ce qui permet de réduire ainsi de manière considérable la quantité de cendres volantes, et d'augmenter la quantité de production de scories.
