Experimental investigation on possibility of oxygen enrichment by using gradient magnetic fields

CAI Jun, WANG Li, TONG Lige, SUN Shufeng, WU Ping

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 3,   Pages 271-276 doi: 10.1007/s11705-007-0049-x

Abstract: This paper presents a novel method that uses the interception effect of gradient magnetic field on oxygenmolecules to realize enrichment.Thus, continuous oxygen enrichment is realized.The enrichment degree of oxygen reaches 0.65% when the inlet and outlet air flows are 40 mL/min and 20enrichment degree than other oxygen-enrichment methods using magnetic separation.

Frontiers in Energy 2011, Volume 5, Issue 4,   Pages 398-403 doi: 10.1007/s11708-011-0157-7

Abstract: The use of different levels of oxygen-enriched air was compared with respect to percentage load.Increasing the oxygen content in the air leads to faster burn rates and increases the combustibilityat the same stoichiometry (oxygen-to-fuel ratio).The power increases considerably with oxygen enrichment.In addition, oxygen enrichment can also be considered as a way to reduce the sudden loss in power output
