Major benefits for retrofits and new fossil fuel and biomass power plants:
- NOx is greatly reduced with properly designed combustion and burner systems without any back-end emissions control technology. In fact, coal combustion NOx levels in the exit gas are below the federal goal of 0.1 Lbs/MMBtu, and are expected to be 0.05Lbs/MMBtu without any post-combustion emission controls.
- Flue gas exhaust from the boiler is approximately one-forth that of air-ﬁ red boilers, making emission capture easier, as well as more effective and economical.
- CO2 becomes highly concentrated, making capture easier and more economical with 95%+ capture of CO2 possible. Since air is not part of the combustion process, there is no expense to separating CO2 from air prior to compression, unlike with air ﬁring.
- Elimination of key pollutant emissions: 99%+ SOx, 99%+ PM and 90%+ mercury capture
- Fuel efficiency is improved because nitrogen uses up a great deal of heat/energy produced by combustion. Furthermore, the patented high ﬂame temperature process improves radiant heat transfer and therefore efﬁ ciency. Test results from retroﬁtting older natural gas boilers show a 6.7% to 14.3% drop in fuel consumption in the boiler based on patented high ﬂame temperature oxy-fuel combustion. Less fuel also means a corresponding reduction of greenhouse gases and pollutants.
