Abstract:To investigate the rules of transformation during coal combustion,experiments were carried out for model compound pyridine and the results via Fourier transform infrared radiation analyzer show that the ring cleavage of pyridine occurs at 750¡æ£¬the quantity of nitriles is produced mostly at 850 ¡æ,and N2O is transformed from nitriles.Beginning from 6.0 of rO£¬the productivity of the N2O increases rapidly with the increasing of the oxygen.In the state of oxygen deficit,the high condense CO makes the transformation of NOxmore difficult.N2O transforms into NO and NO2 completely when the temperature is above 1 000 ¡æ.NO and NO2are mainly transformed from HCN£®
