Request PDF on ResearchGate | Pulverized Sponge Iron, a ZeroCarbon and Clean Substitute for Fossil Coal in Energy Applications | The direct combustion of recyclable metals has the potential to ...
The direct combustion of recyclable metals has the potential to become a zerocarbon energy production alternative, much needed to alleviate the effects of global climate change caused by the increased emissions of the greenhouse gas CO2. In this work, we show that the emission of CO2 is insignificant during the combustion of pulverized sponge iron compared to that of pulverized coal combustion.
The process of sponge iron manufacturing involves removal of oxygen from iron ore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. Hence the name sponge iron.
