Blast Furnace an overview ScienceDirect Topics

The typical blast furnace gas composition in volume is N 2 = 55.19%, CO = 20.78%, CO 2 = 21.27% and H 2 = 2.76% (Hou et al., 2011). The water content is removed by demisters following the cleaning process. This gas is used for the furnace mills, in gas engines

What is the Composition of BFS (Blast Furnace Slag)?

Blast Furnace Slag is shaped when iron pellets or iron ore, coke, and limestone or dolomite (Flux) are heated together in a blast furnace. When the metallurgical melting procedure is finished, the lime in the flux has been chemically united with the aluminates and silicates of the ore and coke ash to procedure an outcome named blast furnace slag which is non-metallic.

Ground Granulated Blast Furnace Slag

Composition. Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. GGBFS is divided into three classifications based on its activity index. Grade 80 has a low activity index and is used primarily in mass structures because it generates less heat than portland
