Energy Conservation and CO2 Abatement Potential of a Gas-injection Blast Furnace

Blast Furnace Granular Coal Injection Project

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...

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...

Comparison of Co2 Abatement by Use of Renewable Energy and Co2 Capture and Storage

Emissions of CO2 and other greenhouse gases to the atmosphere will need to be greatly reduced to avoid the risk of harmful climate change. There are many different ways of reducing emissions of greenhouse gases. It is important to be able to understand how the different options compare. This paper includes a comparison of the costs of three different options for reducing emissions of CO2; wind ...

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...
