Air Products is offering for license a method for oxygen-enhanced combustion using a vent stream of nitrogen generator. In order to improve productivity and thermal efficiency of the heating and melting process, oxygen enhanced combustion is utilized. Oxygen is proven to provide benefits in the combustion process; notably increasing productivity and fuel efficiency, while reducing flue gas volume and pollution. Oxygen has been used in many ways to enhance existing air/fuel fired combustion processes. Although oxy-fuel typically results in the greatest benefit it usually comes with a trade off in cost. This technology is a supplemental benefit to the production of high purity nitrogen by separation from air in a nitrogen plant. In this invention the nitrogen plant is operated to produce a vent, exhaust or waste stream having by volume 40-90% oxygen balanced nitrogen, atmospheric gases, and impurities such as CO2 and H2O.
- Increased productivity
- Increased fuel efficiency
- Reduced flue gas volume
- Reduce pollution emissions including Nox
