【摘要】 选取１０种动力用煤在循环流化床上进行了燃烧试验，研究了煤的挥发分含量、含碳量、含氮量等煤质特性对循环流化床中Ｎ２Ｏ和ＮＯｘ的生成及氮转化率的影响，并对循环流化床中Ｎ２Ｏ的生成与分解机理进行了分析。更多还原

【Abstract】 Ten kinds of coal widelty used in power plants have been tested during circulating flu-idized bed combustion to study the influence of coal properties such as volatikmatter con- tent , nitrogen content etc,on N2O and NOx formation. The converting rate of nitrogen intoNO2 is also studied t has been found that (a) N2O formation is independent of O/N ratio;(b)The higher the nitrogen content of coal is,the higher the N2O emission and the convert-ing rate of N into N2Owill be; and(c)homogeneous oxidation of HCN is an important wayof N2Oformation. The mechanism of N2O generation and decomposition is analyzed.更多还原
