Oxygen-Enriched Combustion Systems (OECS)
High-Efficiency Combustion Technology | Teamwin & Yuanhan Energy Partnership
Greenox Gases delivers advanced Oxygen-Enriched Combustion Systems (OECS) through strategic collaborations with Teamwin (equipment fabrication) and Yuanhan Energy (process optimization), offering industries higher thermal efficiency, reduced fuel consumption, and lower emissions.
An Oxygen-Enriched Combustion System (OECS) is a combustion process where the oxygen concentration in the oxidant (usually air) is increased above normal atmospheric levels (21% O₂) by adding industrial oxygen. This enrichment results in hotter flames, faster combustion, improved efficiency, and reduced emissions.

OECS Technology Overview
How It Works
- Higher flame temperatures (up to 3,000°C)
- Reduced NOx/SOx emissions f(30–60% lower)
- Fuel savings f(15–40% less natural gas/coal)
- Key Partners:
- Teamwin – ASME-certified burners & combustion chambers
- Yuanhan Energy - AI-driven O₂ control systems
