Blast Furnace Coal Injection Trial Results Using Granulated and Pulverized High Volatile Coal

INTRODUCTION This report presents the results of two trials conducted with the Blast Furnace Granular Coal Injection System at Bethlehem Steel Corporation's Bums Harbor Plant. The trials were conducted using granulated and pulverized high volatile coal from Colorado. The first trial was conducted to quantify the effect that a high volatile western coal, Colorado Oxbow, has on the blast furnace ...

Impact of PCI Coal Quality on Blast Furnace Operations

Pulverized coal injection has assisted the steel industry to lower operating costs, extend coke oven life and lower greenhouse emissions. As the understanding of the impact of quality of the injected coal has increased, there has been a shift from high volatile thermal coals to low volatile semi-anthracites. A heat and mass model was used to investigate the impact of the injected coal propertie...

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...

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...
