Oxygen-Enriched Combustion Systems (OECS) for Kiln Efficiency
Greenox Gases provides advanced oxygen-enriched combustion technology specifically engineered to optimize cement kiln operations, reduce fuel costs, and lower emissions in clinker production.
Cement production is energy-intensive and highly dependent on combustion. Industrial gases play an important role in improving efficiency, reducing emissions, ensuring safety, and maintaining product quality.
OECS Technology for Cement Kilns
How It Works
Our Oxygen-Enriched Combustion Systems (OECS) inject 25–95% pure oxygen into kiln burners, replacing ambient air combustion to:
- Increase flame temperature (up to 3,000°C) for better clinker quality
- Reduce fuel consumption by 20–40% (coal, pet coke, or alternative fuels)
- Lower NOx & CO₂ emissions by 30–60%
- Improve kiln stability with precise O₂/fuel ratio control
Key OECS Products for Cement Plants
| System Model | O₂ Enrichment | Capacity | Key Feature |
|---|---|---|---|
| OECS-200 | 25–35% O₂ | 2–10 MW | Retrofit-ready for existing kilns |
| OECS-1000 | 35–50% O₂ | 10–50 MW | AI-driven combustion optimization |
| OECS-5000 | 50–95% O₂ | 50–300 MW | Full oxy-fuel conversion option |
Compliance: Meets EPA, EU BREF, and China GB standards for emissions
Benefits for Cement Production
1. Fuel Efficiency & Cost Savings
- 20–40% less coal/pet coke required per ton of clinker
- Higher specific heat transfer → faster kiln throughput
- Works with alternative fuels (tires, biomass, waste)
2. Emissions Reduction
- NOx cuts by 30–60% (lower thermal NOx formation)
- Lower CO₂ footprint per ton of cement
- Reduced dust carryover (less excess air)
3. Process Optimization
- Stable flame control for uniform clinker quality
- Reduced kiln buildup (more complete combustion)
- Flexible O₂ adjustment (25–95% on demand)
