Combustion is the oxidation reaction between fossil fuels (Natural Gas, Oil, Coal) and an oxidizing agent.
The ways of improving the combustion efficiency is increasing the temperature of the oxidizing agent or using oxygen as the oxidizing agent.
Combustech has commercialized both combustion technologies and is the only company worldwide developing and providing such burners.
Combustech’s oxy-fuel and oxygen-enriched combustion products have been proven in the field through differentiated technology and know-how. Our products can contribute to energy savings, productivity improvement and emission reduction.
Features of Oxygen Combustion
More than 50% of energy saving
By using oxygen as the oxidizing agent, the combustion efficiency is more than doubled as compared with the conventional air combustion system because nitrogen, which is a substance which hinders the combustion as it absorbs the heat without heat transfer, is removed.

More than 80% of emission reduction
As nitrogen, which accounts for 80% for conventional air combustion, is removed, the emissions after combustion is reduced by 80%. The CO2 emission reduces as much as the fuel savings.

Reduced equipment costs and easy maintenance
Oxy-fuel burners have 1/4 the volume, 1/2 the weight and 1/5 the pipe size of a conventional air burners.
The exhaust duct and the downstream equipment size can be reduced as the exhaust gas decreases by 80%.
Simple system means that maintenance is simple and easy.
Wide turn down ratio (15:1)
The limit of inflammability of an oxy-fuel burner is more than 3 times the conventional air burners, which allows a turn down ratio of more than 15:1, unachievable for conventional air burners.
This enables a single burner to be used for various operation from low to high calorific operation.
