中文摘要:
在煤的石块燃料消费和污染物质排出物开除了使流体化的床锅炉能被重新烧的生物资源热分解气体减少。在实验室规模的 N2O 的排放上的三种生物资源热分解气体的影响使流体化床在这份报纸用 GRI3.0 的机制被调查。结果显示出那:锯屑热分解气体的效果在 N2O 上重新烧在一样的条件下面是比米饭外壳和橘子皮的更重要的;在烟道气体的从 1% ~ 8% 的起始的氧内容的增加将制止 N2O 的分解;N2O 分解被从 1073.15 K 增加反应温度到 1323.15 K 提高,并且分解率可以在 1223.15 K 到达 99% 。
英文摘要:
The fossil fuel consumption and pollutant emissions in a coal fired fluidized bed boiler could be reduced by biomass pyrolysis gas reburning. The influence of three kinds of biomass pyrolysis gases on the emission of N2O in a laboratory scale fluidized bed was investigated using the mechanism of GRI3.0 in this paper. The results showed that: the effect of sawdust pyrolysis gas reburning on N2O was more significant than that of rice husk and orange peel under the same conditions; the increase of initial oxygen content from 1% to 8% in flue gas would restrain the decomposition of N2O; the N2O decomposition was enhanced by increasing reaction temperature from 1073.15 K to 1323.15 K, and the decomposition rate may reach 99% at 1223.15 K.
