摘要
在一小型流化床反应器上 ,研究了三种煤在不同温度下燃烧时N2 O的生成性质 ,着重研究了煤挥发分燃烧及焦炭燃烧的不同阶段下N2 O的生成水平及其相互比较。结果表明 :在煤燃烧的不同阶段 ,N2 O的转化率与煤种有关 ;挥发分燃烧时N2 O转化率较高 ,挥发分的含量越高 ,挥发分N2 O转化率越低 ;温度变化对N2
N_2O formation was studied at different temperatures on a bench scale fluidized bed reactor for three different kinds of coals.Special attention was paid to N 2O formation during coal devolatilization and char combustion.Test results indicate that the transformation rate of N 2O depends much on coal rank in different stages of coal combustion.There is a high transformation rate of N 2O during combustion of volatile matter.The higher the volatile content,the lower the transformation rate of N 2O.The most inportant factor influcing N 2O emission is the temperature in furnace.
