生物质燃料与煤混燃时NO_x/N_2O排放的研究

为寻找一种能够有效抑制流化床中NOx和N2O排放的途径．在一个实验室规模的小型鼓泡流化床上进行了生物质燃料（木屑）与煤混燃的研究．结果表明：木屑与煤混燃可以有效地降低NOx和N2O的排放，并且还发现，对NOx和N2O的削减能力与混合比例有关．掺入木屑的比例越大，削减的程度越强，但随温度的升高．削减程度有所下降．对木屑与煤混燃能降低NOx／N2O排放的原因进行了讨论．

On the Emission of NO_x/N_2O during the Co-Combustion of Biomass and Coal

In order to find a way to control the emissions of NOx/N2O from the fluidized bed, a study of the combustion with the biomass and coal mixture has been carried out at a laboratory-scale bubbling fluidized bed reactor. The results show that the emissions of NOx/N2O can be reduced efficiently, and percentage of reduction depends on the ratio of the biomass and coal. The larger the proportion of biomass is, the higher the reduction is. But with the increase of temperature, the degree of reduction decreases in a certain extent. The reasons why the reduction happens are discussed.
