Effect of Coal and Coke Ash on Blast Furnace Slag Properties: A Comparison Between Pulverized Coal, Charcoal, Fossil‐Based Coke, and Biocoke

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 ...

Effects of Blast Furnace Slag with Iron Ore Containing Rare Earth Elements on Combustion Characteristics of Pulverized Coal

The combustion characteristics of pulverized coal when using blast furnace slag charged with iron ore containing rare earth elements as a composite catalyst were investigated by thermo gravimetric analysis. The results show that the combustion char acteristics of pulverized coal loaded with 21.3% by weight of blast furnace slag containing 15% rare earth ore are better than those of others. It i...

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...

Model of pulverized coal combustion in a furnace

We describe behavior of the air-coal mixture using the Navier–Stokes equations for gas and particle phases, accompanied by a turbulence model. The undergoing chemical reactions are described by the Arrhenian kinetics (reaction rate proportional to exp ` − E RT ́ , where T is temperature). We also consider the heat transfer via conduction and radiation. Moreover we use improved turbulence-chemist...
