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

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 activitiesis very low and varies from 0.1% to1%, and the methane is contained in a large air flow rate of 150–, and then presents research progress in developing an innovative lean burn catalytic turbine technologyfor fugitive methane mitigation and utilization.This turbine system can be powered with about 1% methane in air.
