Exhaust Gas Handling TRIZ Cases
- Hydrogen-Reduced DRI Pellets With Low Reactivity and High Strength
Hydrogen reduction produces highly metallized DRI pellets with controlled porosity, lowering oxidation risk while improving strength for handling and storage.
- Shaft Furnace Gas Composition for Hydrogen-Based Reduced Iron
Nitrogen-assisted hydrogen reduction in a shaft furnace cuts gas intensity and reuses reduced-iron heat to improve thermal efficiency.
