Model Study of Blast Furnace Operation with Central Coke

Blast furnace BF remains the dominant ironmaking process worldwide. Central coke charging CCC operation is a promising technology for stabilizing BF operations, but it needs reliable and quantified process design and control. In this work, a multi-fluid BF model is further developed for quantitatively investigating flow-thermal-chemical phenomena of a BF under CCC operation.

Why Use Coke for Blast Furnace Ironmaking not Use Coal

Let me talk about the use of coke. In the blast furnace ironmaking, coke has the functions of column skeleton, reduction, carbon supply, and heat supply. Column skeleton: The coke heap density in the blast furnace charge is the smallest, the gap is large, and the volume accounts for 35%-50% of the total volume of the charge.

Blast Furnace Coke Properties and - DiVA portal

1.1.1 Coke-making process Blast furnace coke is produced by heating coking coal to high temperature in the reducing atmosphere of the coke oven. 1 The coal-to-coke transformation is illustrated in Figure 1. 4 The coal mix is heated from the oven walls on each side of the coke oven and two plastic layers are developed on each side and converge

How a Coke Plant Works - GASP

Coke is used as fuel in a blast furnace. It plays an important role in the chemical processes that take place in a blast furnace. Coal is heated to about 1250 degrees Celsius in the coke ovens. This process is referred to as ‘dry distillation’ because these coke ovens are oxygen free, so the coal does not actually burn.

Blast furnace - Wikipedia

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 & 34;forced& 34; 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

Coke Mineral Transformations in the Experimental Blast Furnace

Blast furnace efficiency may be improved by optimizing coke reactivity. Some but not all forms of mineral matter in the coke modify its reactivity, but changes in mineral matter that occur within coke while in the blast furnace have not been fully quantified. To determine changes in mineral matter forms in the blast furnace, coke samples from a dissection study in the LKAB experimental blast

and blast furnace performance. They are related to the viability of the blast furnace, improvement in blast furnace productivity and efficiency, and blast furnace operations at lower coke rates. The most consistent theme of recent literature is that the blast furnace will remain a dominant method for production of hot metal worldwide 2-9 .

Effect of Temperature on Coke Properties and CO2

Experimental Blast Furnace In the current study, coke samples were obtained from a dissection study based on 10th campaign of the Experimental Blast Furnace EBF at Luleå using high CSR coke. The CSR and CRI values of coke used were 68.8 and 23.15 respectively while fuel and coke rates were of the order of 500 kg/thm and 350 kg/thm respectively.

Blast furnace metallurgy Britannica

Blast furnaces produce pig iron from iron ore by the reducing action of carbon supplied as coke at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft the stack that extends from
