blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.
Furnace coke is gray in color and is a hard, porous fuel that has a high carbon content. This material is made by heating coal or oil without the presence of air, which creates a unique destructive distillation process. Furnace coke is actually quite an important industrial product that is often used for iron ore smelting, fuel for stoves, and ...

A vertical tube furnace was used to obtain kinetics data for the reaction of sized fractions of residual fuel oil coke particles with oxygen. Temperatures were in the range 1287 to 1795 K and oxygen concentrations were between 0.29 and 4.95%, and were chosen to simulate large boiler plant conditions.

The cupola (Fig. 48) is a simple melting furnace for cast iron usually working on cold, low pressure blast though hot blast is now sometimes used and even oxygen enrichment, usually as a control on temperature.Pig iron, scrap and coke are charged at the top over a large coke charge for preheating the furnace and providing a continuous reducing bed through which the iron …
The formed coke process (FCP) utilizes noncaking coal as the main raw material. Next, a binder is used to allow the coal to be shaped, and then it is carbonized in formed shapes in a vertical furnace to obtain coke. 2. Features˜ A series of steps are employed in FCP, including raw material processing, shaping, carbonizing the formed coal, and ...
Blast furnace – Blast furnace is essentially a counter-current moving bed vertical shaft metallurgical furnace with solids (iron bearing burden, coke and flux), and later molten liquids, travelling down the shaft. It is used for smelting iron ore to produce liquid iron.
