Advanced clean-energy technology for a sustainable tomorrow.

Direct Steam Gas Generators

OxCE has developed an innovative oxy-fuel combustion system that uses natural gas and oxygen to power, steam, and/or heat for industrial processes with near zero emissions. OxCE’s proprietary technology is an oxy-combustion burner (“direct steam gas generator” or “DSGG”) which combusts natural gas with oxygen, in a highly efficient manner. Clean, firm power plants using OxCE technology produce baseload electricity and a high-purity CO2 stream, which is ready for downhole sequestration or beneficial re-use in other industrial applications. Waste heat can also be captured for use by a co-located industrial user, meaning that the clean, firm plants could operate as co-generation facilities. OxCE technology is highly advantaged compared to post-combustion carbon capture, as it is both lower cost and can capture almost 100% of the CO2 emissions.

OxCE technology is both compact, modular and scalable. Oxy-combustion burner units are packaged in transportable containers, minimizing the required on-site installation time.  OxCE can support 20-300+ MW projects, using existing proven technology.

OxCE’s DSGG consist of three main parts: a burner, attemperator, and associated feed and controls systems. DSGG burners utilize platelet technology to intimately mix gaseous fuel with oxygen in the presence of water for stable, efficient combustion. Multiple attemperation chambers inject water to cool the resulting superheated, high-pressure steam and CO2, producing additional steam and controlling combustion. Associated water, oxidizer, and fuel feeder systems are designed for the specific fuel qualities targeted in your project. Oxygen is supplied by a traditional air separation unit (ASU).
