| 内容記述 | The NASA Space Technology Mission Directorate Center Innovation Fund at Kennedy Space Center (KSC) funded a one year investigation for the development of a micro-scale plasma arc gasification system for waste repurposing on long duration space missions. The reuse of discarded materials on a long duration or planetary mission is a critical component in reducing overall mission mass and creating useful commodities like fuel, water and repurposed construction materials. Plasma arc gasification converts the majority of organic waste into a synthesis gas (syngas), consisting primarily of hydrogen, carbon monoxide and carbon dioxide, and inorganic waste into a solid slag material that can be used as a construction aggregate. Plasma arc gasification had not been previously investigated for space appilcations, and potentially provides a cleaner product than other waste processing methods. The micro-scale plasma arc gasification system was designed, fabricated, and tested at KSC with a commercial plasma torch. This paper will discuss the project development and results regarding the use of plasma at low power and the challenges of plasma arc gasification for small scale waste conversion. Designing the power supply was the main challenge in this project. Although this plasma torch was successfully operated for short periods of time, the power supplies did not allow for low power operations over long time periods. |
