Jupiter Oxygen, has designed, built and operated a 15 MW thermal boiler test facility in Hammond IN (USA). The boiler began operation in October of 2007. Jupiter Oxygen has completed a series of tests where oxygen has been combusted with coal and natural gas under different conditions. Tests and boiler operation were conducted where flame temperatures reached about 5000F with and without recycle flue gas (while maintaining flame temperature) while burning natural gas. Tests and boiler operation where conducted with recycled flue gas mixed with oxygen resulting in flame temperatures closer to air fired conditions using natural gas. Baseline testing was established using air and natural gas for comparative purposes. Initial testing has also been completed where coal (Illinois No. 6) has been used with oxygen (with and without recycle) resulting in a high flame temperature in the boiler. Initial testing has been completed where the flue gasses from the combustion of coal with oxygen have been captured for the purpose of sequestration investigation. The results to date establish specific advantages for high flame temperature oxy-fuel combustion, indicating an economic pathway for carbon capture from fossil fuel power plants. |
