Influence of the Intensity of a Magnetic Field on the NO_x Production Characteristics During the Laminar Flow Premixed Flame Combustion

With the laminar flow premixed flame of liquefied gas serving as the object of study,set up was a combustion test rig with an electromagnetic field being applied at both sides of the flame to determine the intensity of the field,measure the combustion temperature of the laminar flow premixed flame in the electromagnetic field and NOxconcentration and analyze the laminar flow premixed flame combustion characteristics at various intensities in the magnetic field and production characteristics of NOx. It has been found that under the action of the electromagnetic field,the flame temperature will rise,the flame diameter will slightly increase,its height will somewhat decrease and at the same time,the electromagnetic field will reduce the possibility of N,HCN and CN etc. ion and ion groups in the flame to collide with oxygen,resulting in a decline of NOxconcentration,maximally reduced by 2. 998 mg / m3.
