Blast furnace coke substitutes from Victorian brown

No material can completely replace coke in a BF. Coking coals are becoming harder (and more expensive) to obtain. Victorian brown coal (VBC) is accessible, cheap, with low mineral concentrations, which is favourable for iron production in a BF. However, as-mined, it does not form coke, but a char which is too reactive to be used in a BF.

2015-5-15  Victorian brown coal (VBC) is accessible and cheap with low concentrations of mineral impurities, which is a favorable requirement for blast furnace coke. Minerals, specially metallic iron and iron sulfides, increase coke reactivity and thus reduce its strength (Coke Strength after Reaction, CSR). Therefore VBC has attracted attention as a coke

Coke Vintage Story Wiki

2021-1-12  Brown coal (lignite) or black coal (bituminous) can be used in the oven to make coke. While both take the same amount of time to process, a full stack of brown coal will only yield 8 coke, while an equal amount of black coal will yield 12 coke. To start the process, simply layer coal in the oven, ignite with a torch and close the coke oven door.

2 天前  Coke is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. Cokes from coal are grey, hard, and porous. While coke can be formed naturally, the commonly used form is man-made. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace.

Bituminous coal and coke has a calorific value higher with 75 to 90% carbon and 5 to 10% humidity. Bituminous coking coal, after processing in coke (removal of impurities and addition of oil) is used for reducing iron ore and ferroalloys, in blast furnaces for making steel. It is also used in power stations to generate steam and electricity.
