(Graph 1) Gibbs energy (ΔGV) vs T plots (schematic) for formation of some oxides (Ellingham diagram) Blast Furnace . In the Blast furnace, reduction of iron oxides takes place in different temperature ranges. Hot air is blown from the bottom of the furnace and coke is burnt to give temperature upto about 2200K in the lower portion itself.
Extracting iron from iron ore using a Blast Furnace. Introduction. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air.
In blast furnace, iron oxides are reduced at different temperature ranges. In the lower part of the blast furnace, the temperature is as high as 2 2 0 0 K. It is called combustion zone. At the top, the temperature is as low as 5 0 0 − 8 0 0 K. It is called reduction zone.
Equations were also derived for the constraints of the Carbon-Direct Reduction (C-DRR) diagram, showing that this diagram and the Rist diagram emphasize different variables of the same model. An interpretation of the constraints operating in the diagrams is also given from the point of view of blast furnace operating practice.
A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

Blast Furnace. Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500's.
1. The diagram shows the Blast Furnace for the extraction of iron from its ore, taken as haematite. Write the equation(s) for each of the following reactions: a) the formation of carbon monoxide in the furnace; b) two reactions in which haematite is reduced to iron; c) the function of the limestone in the furnace…
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

Pig Iron Production - Blast Furnace Route. More than 1.1 billion tonnes of blast furnace iron was produced globally in 2016. Blast furnace economics are such that larger units have lower unit production costs, hence there has been a trend to bigger and bigger furnaces. Modern blast furnaces produce more than 10,000 tonnes per day.
Iron is extracted from iron ore. in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2 O 3 . The oxygen must be removed from the iron(III) oxide in ...
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3. Haematite is added to the top of the furnace along with coke (i.e ...
