摘要
In this paper, the flame stabilization and NOx emissions of CH4/NH3/air premixed swirl flame assisted by the gliding arc plasma are studied. The results show that the gliding arc can not only greatly expand the lean blowout limits of CH4/NH3/air premixed swirl flame (in the unconfined and the confined cases, the lean blowout limit are extended from 0.60∼0.80 to 0.30, respectively), but also reduce NOx emissions. Subsequently, the possible mechanism of gliding arc plasma to reduce NOx emissions was analyzed through the optical measurement of NH2∗ chemiluminescence. © 2022, Science Press. All right reserved.
