CFD Modelling and Analysis of Pulverized Coal Injection in Blast Furnace: An Overview

Journal Article


Abstract


  • In order to understand the complicated phenomena of pulverized coal injection (PCI) process in blast furnace (BF), several mathematical models

    have been developed by the UNSW and BSR cooperation. These models are featuring from coal combustion in a pilot-scale test rig, to coal

    combustion in a real BF, and then to coal/coke combustion in a real BF, respectively. This paper reviews these PCI models in aspects of model

    developments and model applicability. The model development is firstly discussed in terms of model formulation, their new features and

    geometry/regions considered. The model applicability is then discussed in terms of main findings followed by the model evaluation on their

    advantages and limitations. It is indicated that the three PCI models are all able to describe PCI operation qualitatively. The model of coal/coke

    combustion in a real BF is more reliable for simulating in-furnace phenomena of PCI operation qualitatively and quantitatively. Such model gives a

    more reliable burnout prediction over the raceway surface, which could better represent the amount of unburnt char entering the coke bed. These

    models are useful for understanding the flow-thermo-chemical behaviours and then optimising the PCI operation in practice.
