abstract

Pulverized Coal Injection (PCI) is a technique that has been applied to blast furnaces over the last several decades. Due to the increased fuel economy seen in furnaces utilizing pulverized coal technology, several companies are in the process of developing a new hot oxygen injection technology in a charcoal based blast furnace. Computational Fluid Dynamics (CFD) has been employed to obtain a better understanding of this new technique. In the current study, a 3D multiphase reacting CFD model had been developed to evaluate the utilization of a very high temperature, high velocity stream of oxygen in a PCI tuyere. With the use of hot oxygen, both the injection and combustion rates of the charcoal fines in the blast furnace tuyere have been dramatically increased and contribute to the reduction of the lump charcoal consumption rate of the furnace. Parametric studies of different oxygen and PCI lance locations have also been conducted. The simulation results provide insight into optimization of the lance configuration to achieve maximum combustion performance and avoid overheating of the tuyere.
