    • Method of heating a mineral feedstock in a firing furnace of the tunnel furnace type, having a hearth with an upstream inlet, a downstream outlet and sidewalls fitted with burners, in which method the feedstock is transported as a layer of approximately constant thickness along a treatment path in which the feedstock is heated and fired by means of said burners so as to obtain a fired product, said path being located between the upstream inlet and the downstream outlet of the furnace, characterized in that said burners comprise at least one fuel injector and at least one oxidizer injector and are positioned and oriented in such a way that their flames do not impact the layer, the at least one oxidizer injector being positioned relative to the at least one fuel injector so that the at least one fuel jet injected by the at least one fuel injector is separated from the layer by at least one oxidizer jet injected by at least one oxidizer injector.
    • 在隧道炉类型的炉子中加热矿物原料的方法,具有带有上游入口的炉底,装有燃烧器的下游出口和侧壁,其中所述原料沿着处理被输送为大致恒定厚度的层 其中原料通过所述燃烧器被加热和燃烧,以便获得燃烧产物,所述路径位于炉的上游入口和下游出口之间,其特征在于,所述燃烧器包括至少一个燃料喷射器和 至少一个氧化剂注射器并且被定位和定向成使得它们的火焰不会影响该层,所述至少一个氧化剂喷射器相对于所述至少一个燃料喷射器定位,使得由所述至少一个燃料喷射器 至少一个燃料喷射器通过由至少一个氧化剂喷射器注入的至少一个氧化剂射流与该层分离。
