Oxygen-Enriched Combustion System

Product Overview

The oxy-fuel combustion system uses pure oxygen or oxygen-enriched air instead of regular air as the combustion medium, producing mainly CO₂ and water vapor while ensuring complete combustion.

After cooling and condensing the water vapor, the flue gas contains 80–98% CO₂, making it easier to compress, dry, and further purify for efficient storage and transport. The system is designed to optimize CO₂ separation and capture, significantly reducing downstream processing costs.

Working Principle

By using pure oxygen or oxygen-enriched air as the combustion medium, the fuel burns with sufficient oxygen, maximizing CO₂ and water vapor formation.

After cooling and condensation of the water vapor, the CO₂ concentration in the flue gas rises to 80–98%, facilitating compression, drying, and purification. Advanced air separation units—including polymeric membranes, pressure swing adsorption (PSA), and cryogenic distillation—provide a reliable oxygen supply, ensuring stable combustion and efficient energy utilization.
