Blast Furnace, Coke Gas and Converter Blast Furnace Gas Blast furnace gas is a byproduct of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around /Nm 3, which on its own is typically not high enough for combustion in a gas engine.

Coke degradation in a blast furnace occurs due to chemical, mechanical and thermal effects. At higher flame temperature, cracking of coke is mainly attributed to thermal stress while at lower temperatures, the degradation behaviour is influenced by coke reactivity which is dependent on other coke properties. The coke reactivity can be influenced by its three major properties namely ...

In blast furnace ironmaking coal is not as strong as coke, and crushing will cause a decrease in the permeability of the blast furnace. The calorific value and carbon content of some anthracite coals are higher than coke, but there are more harmful impurities such as phosphorus and sulfur in coal. As the combustion enters molten iron, the quality of subsequent steel will be affected. Comparing ...

A. Physical Coke Properties A high quality coke is characterized by a definite set of physical and chemical properties that vary within a narrow limit thereby ensuring consistency in the quality. Coke is the only solid material remaining below the cohesive zone in the blast furnace (Refer figure – A for various zones of operation in blast furnace). Hence, coke must provide the strength to ...

Figure 3 shows a typical control scheme, where the blast furnace gas flow rate is inferred by subtracting the natural gas and coke oven gas flow rates from the total mixed gas flow rate. This calculated value is then used as a ratio setpoint for the natural gas and coke oven gas control blocks, keeping the proportion of each type of gas entering the stove constant and achieving the desired ...

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. Today there are three ...

When demand for coke is low, coking times can be extended to 24 hours for blast furnace coke and to 48 hours for foundry coke. Coking temperatures generally range from 900° to 1100°C (1650° to 2000°F) and are kept on the higher side of the range to produce blast furnace coke. Air is prevented from leaking into the ovens by maintaining a positive back pressure in the collecting main of ...
