Published: 28-09-2018Blast furnace coke substitutes from Victorian brown coal . By Mamun Mollah. Abstract. Iron is usually produced from its ores using coke in a blast furnace (BF). Coke, a hard and macroporous carbon material, is produced from special coals (coking coals) and acts as fuel, smelting agent, and the permeable support for the charge to the BF. No material can completely replace coke in a BF. Coking …

For this, the substitution of fossil carbon with biocarbon has been proposed. The first option is to use biocarbon as a component of the pulverized coal injection (PCI), which takes place through tuyeres in the lower part of the blast furnace.

A substitute for metallurgical coal in blast furnace applications without the availability and cost constraints of current products.

Blast furnaces need coal, but there is an alternative technology called an Electric Arc Furnace (EAF). This is responsible for approximately 30% of the world’s steel production and does not require coal. But it does require an input of pig iron which does usually require coal. Which brings us to…

· PDF fileReplacing Coal Used in Steelmaking with Biocarbon from Forest Industry Side Streams In Finnish blast furnaces over 1.5 million tonnes of coal is used annually both as an energy source and as a necessary reductant to produce over 2.5 million tonnes of raw steel. The respective CO 2 released forms ca. 7 % of the greenhouse gas emissions in Finland. At sawmills and biorefineries, nearly 10 million m 3 of …
