…To make this heat transfer and reaction process more efficient, the furnace is vertical and the alternating layers of iron ore and coke (or charcoal) are placed high. Historically, this is why it is called a blast furnace (Hochofen in German, haut fourneau in French), but on the other hand, a high-pressure, high-velocity blast of air is required to send air from the bottom of the furnace to the high packed beds, and in English it is called a blast furnace, focusing on this blast of air. Currently, blast furnaces around the world are broadly divided into coke blast furnaces and charcoal blast furnaces, but charcoal blast furnaces are limited to parts of Southeast Asia and Brazil, where there are fast-growing trees such as palms and eucalyptus, and most blast furnaces in the world are coke blast furnaces. … *Some of the terminology that mentions "Hochofen" is listed below.
