Compare Pilot-Scale And Industry-Scale Models Of Pulverized Coal Combustion In An Ironmaking Blast Furnace, Yansong Shen, Aibing Yu, Paul Zulli Jan 2013

Compare Pilot-Scale And Industry-Scale Models Of Pulverized Coal Combustion In An Ironmaking Blast Furnace, Yansong Shen, Aibing Yu, Paul Zulli

Faculty of Engineering and Information Sciences - Papers: Part A

In order to understand the complex phenomena of pulverized coal injection (PCI) process in blast furnace (BF), mathematical models have been developed at different scales: pilot-scale model of coal combustion and industry-scale model (in-furnace model) of coal/coke combustion in a real BF respectively. This paper compares these PCI models in aspects of model developments and model capability. The model development is discussed in terms of model formulation, their new features and geometry/regions considered. The model capability is then discussed in terms of main findings followed by the model evaluation on their advantages and limitations. It is indicated that these PCI …


Blast Furnace Hearth Refractory And Coke Ash Mineral Interactions, P B. Drain, M W. Chapman, R J. Nightingale, B J. Monaghan Jan 2013

Blast Furnace Hearth Refractory And Coke Ash Mineral Interactions, P B. Drain, M W. Chapman, R J. Nightingale, B J. Monaghan

Faculty of Engineering and Information Sciences - Papers: Part A

In the blast furnace hearth the calcium aluminate by-products of coke dissolution can react with the hearth refractories. Reactions between these coke ash minerals and the aluminosilicate and alumina-carbon hearth refractories may result in increased refractory wear reducing the blast furnace campaign life. Hence improved understanding of these interactions may have implications for the campaign life of the blast furnace hearth refractory materials. The interactions between the coke ash minerals and aluminosilicate hearth refractory have been assessed by heating samples of calcium aluminates (CA, CA2 & CA6) coupled with aluminosilicate refractory to temperatures representative of the blast furnace hearth (1450 …
