external fuel(During steelmaking by Bessemer converter no external fuel was applied and the whole of the heat requirement was furnished by the oxidation of the impurities, together with that of some of the metallic iron. 贝塞麦转炉炼钢期间，无需添加外来燃料，所需的全部热量均由杂质和部分金属铁的氧化热提供。)
fuel injection(【技】从风口向炉缸喷吹燃料并在风口区迅速燃烧气化的技术。它不仅可以节约焦炭，同时还可改善高炉间接还原，有利高炉顺行高产。: Fuel injection at the tuyeres has always been part of normal operating practice on this blast furnace. 风口喷吹燃料已经是这座高炉正常操作的一部分。)
fuel consumption(When a cold blast of air was used, as much as eight long tons of coke were needed to produce one long ton of pig iron. In 1828, a Scot, James Neilson, developed the use of a heated blast and, as a result, the fuel consumption was reduced to five long tons per long ton of iron. 使用冷鼓风时，生产 1 英吨生铁需要消耗多达8英吨焦炭。1828年，苏格兰人詹姆斯・尼尔逊研发出热鼓风的使用，使得每英吨生铁的焦炭消耗降至5英吨。)
tuyere-injected fuel(The net energy introduced into the ironmaking process by the combustion of coke and tuyere-injected fuel to CO and H₂ and the sensible energy of the blast is 3. 75 gigajoules per tonne of hot metal. 该炼铁工艺引人的净能量为37. 5亿J/t 铁，来源于焦炭和风口喷人燃料燃烧生成的一氧化碳和氢气以及鼓风显热。)
