Oxygen enrichment to reduce NOx emissions
Oxygen enrichment to drastically reduce NOx emissions in a green glass and flint production company.

- Introducing oxygen into steel reheating furnace process in order to reduce energy consumption.
- Overview of the Mini Mill process:
- Electric arc furnace produces molten steel
- Molten steel enters a steel refining facility
- Undergoes continuous casting
- After which enters the reheat furnace
- Produces final products: structural profiles, bars, slabs, etc.
1. Initial inspection of the furnace in order to fully understand the problem
2. Taking into account (amongst others):
– Furnace type
– Nominal production rate
– Actual throughput
– Charge dimensions
– Specific energy consumption
– Internal pressure
3. Split into multiple cases to properly simulate the problem and model the solutions
4. Installed an oxygen control skid with automatic flow control (0-900nm³/h) and electric cabinet with PLC and HMI screen
- The solution was a success, with good operation and no instances of quality problems, temperature problems or refractory damage
- This resulted in energy savings (8.3% average), reduced CO₂ emissions (4.6 kg/Ton average) and reduced production costs
