| Abstract Scope |
The blast furnace operates on principle of reducing iron oxides using carbon monoxide, producing molten iron and slag. The utilization of waste plastic as substitute for pulverized coal injection is an avenue for addressing environmental and economic concerns. This study investigates feasibility and potential benefits of co-injecting waste plastic particulate blend with natural gas. The aim of this work is to assess viability of waste plastic injection (WPI) using CFD simulation, particularly with respect to flame temperatures, combustion efficiency, coke replacement ratio, emissions reduction, and sustainability. By examining combustion characteristics of waste plastic particulates and their interaction with combusting natural gas, this research seeks to establish viable injection parameters which maintain stable flame temperatures and result in complete combustion of injected material. Further modeling is used to establish how WPI influences reduction reactions and production in the blast furnace shaft region, potentially enabling reduction in the blast furnace’s environmental footprint. |
