Oxy-Fuel Combustion is a technology within the broader carbon capture technologies. Jupiter Oxygen’s patented high flame temperature oxy-fuel combustion system is part of a new set of cleaner fossil energy technology, carbon capture, which has emerged to act as a bridge from conventional fossil fuels to abundant clean and sustainable forms of energy. In 1997, Jupiter’s technology moved from invention to daily use in large industrial melting furnaces, Since 2001, Jupiter has taken its technology from industrial furnaces to fossil fuel steam boilers and electric power plant applications. In 2002, the company tested its oxy-fuel technology in a steam boiler using oxygen instead of air, firing with both natural gas and coal. These successful power plant quality steam tests were followed by additional testing in 2004 that proved that it is both practical and cost effective to capture CO₂. Jupiter has achieved its developmental goals for its patented oxy-fuel technology with coal and other fossil fuels, i.e. to greatly reduce NOx and other pollutant emissions even without carbon capture, prove that CO₂ can be effectively and economically captured, and to improve boiler energy efficiency in order to save fuel. The results demonstrate a practical and economic solution to clean up fossil fuel power plants carbon emissions and key pollutants in an integrated system.
Jupiter Oxygen Corporation's patented fossil fuel combustion technology uses a high temperature flame with 95% to 100% pure oxygen for combustion while air is excluded. Therefore, there is no airborne nitrogen. Nitrogen uses energy during combustion, thereby reducing the amount of energy available to be transferred to the water tubes for the making of steam. Lower nitrogen means that more combustion energy is available for making steam. The oxy-coal flame is at a much higher temperature and generates far more radiant energy transfer than an air-coal flame [also true using other fuels]. Radiant heat transfer is far more efficient than convective heat transfer. (Note that the higher flame temperature can be safely used for power plant retrofits with existing materials and existing process temperatures). Furthermore, Jupiter's combustion technology operates at or very close to stoichiometry and creates longer residence times. This means that there is a more efficient burn of the fuel and more time for the energy generated to be absorbed as the heated gas passes through the boiler.
These four factors [reduction of nitrogen at combustion, greater radiant heat transfer, stoichiometric oxygen-fossil fuel ratio and longer residence times] mean that Jupiter Oxygen’s technology makes boiler combustion become much more efficient and use significantly less fuel to create the desired megawatts. In addition, exit gas emission clean-up with back-end technologies are more efficient and less costly because of lowered NOx at combustion with air excluded, lower pollutants due to the fuel reduction, reduced exit gas volumes and the changed composition of the exit gases. The Jupiter Oxygen patented technology also results in more concentrated CO₂, resulting in less expense capture and sequestration. Initial test results showed a tenfold increase in CO₂ concentration.
