Maximising the efficiency of your combustion process
Oxyfuel combustion can make a valuable contribution to improving the carbon balance of fossil fuel combustion. With this process, coal is combusted in an atmosphere consisting of pure oxygen and carbon dioxide (CO2). This purer mixture burns at a higher temperature than natural air, thus increasing the efficiency of the combustion process.
Additionally, the resultant flue gas is not diluted by nitrogen normally present in air, but primarily consists of CO2 and water vapour. The flue gas stream is therefore smaller and easier to handle.
This vapour is easily condensable, leaving a highly concentrated CO2 stream. The CO2 can then be compressed and stored.
We support oxyfuel combustion by providing
- the air separation unit for the production of oxygen
- the CO2 compression, drying and purification system and
- the liquefaction system (optional).
