Abstract
The effect of three-dimensional (3D) rotating gliding arc (RGA) discharge plasma on the stability of ammonia/air swirling flames is experimentally investigated. The properties of the plasma were characterized, and the combustion-supporting effect of the plasma was quantitatively studied. The flame stabilization mechanisms by plasma were revealed and analyzed according to the flame structure transition and the distribution of OH radicals. The results show that the RGA discharge plasma can be used as an ignition source and a flame stabilizer, and improve the flame stability and extend the lean blow-off limit. In addition, the flame hysteresis phenomenon disappears at high flow rates. Last, the ammonia flame is affected by the hydrodynamic instability of the electric field/plasma at low flow rates.
