Progress in developing an innovative lean burn catalytic turbine technology for fugitive methane mitigation and utilization

Shi SU, Xinxiang YU

Frontiers in Energy 2011, Volume 5, Issue 2,   Pages 229-235 doi: 10.1007/s11708-011-0147-9

Abstract: Approximately 2.8 × 10 m of methane is emitted per year to the atmosphere from coal mining activities around the world. Mitigation and utilization of the fugitive coal mine methane is very difficult because its concentration is very low and varies from 0.1% to1%, and the methane is contained in a large air flow rate of 150–400 m /s. This paper overviews existing and developing technologies for the mitigation and utilization of the fugitive mine methane, and then presents research progress in developing an innovative lean burn catalytic turbine technology for fugitive methane mitigation and utilization. This turbine system can be powered with about 1% methane in air.

The Electrically Controlled Flame Synthesis of Oxide Nanop article

Zhuang Qingping

Strategic Study of CAE 2007, Volume 9, Issue 2,   Pages 74-78

Abstract:

For precise control of the nanophase powder characteristics, electrically assisted hydrocarbon flames using electrodes have shown quite effective, either by ion or electron attachment, so the coagulation rate of the particles is reduced, as unipolarly charged particles repel each other. Charged particles are also attracted towards electrodes, thus lowering the local particle concentration and therefore the collision rate. The flame structure, height, and temperature are also altered by the electric field, which can significantly influence the particle residence time at high temperatures and therefore affect particle growth or sintering and crystallinity. It was shown that field generated by the electrodes across the flame decreases the particle residence time in the high temperature region of the flame.
