Fuel Injection into the Blast Furnace

Blast Furnace Granular Coal Injection Project

Blast Furnace Granular Coal Injection System Demonstration Project

The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and technica...

Ground Granulated Blast Furnace Slag

1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

The Study of Ion Adsorption by Amorphous Blast Furnace Slag

In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...

Char refiring under O2/N2 and O2/CO2 atmospheres. Implication for PCI injection in blast furnace

It is attempt in pulverized coal injection (PCI) in blast furnace tuyeres to increase the injection rate without increasing the amount of unburned char inside the stack of the blast furnace. The unburned char can cause problems in the blast furnace operation, such as reduced permeability, undesirable gas/temperature distribution, excessive coke erosion and significant char carryover. In the nea...
