油页岩循环流化床燃烧N_2O生成特性及控制技术

Characteristic and Controlling Method of N_2O Emission Property of Oil Shale of Circulating Fluidized Bed Combustion

在一个直径 2 0mm ,高 4 5 0mm小型热态循环流化床燃烧试验台上 ,对一些可调整的运行参数对油页岩循环流化床燃烧过程中N2 O排放特性影响的试验研究 ,试验研究表明 ,降低过量空气系数、提高循环倍率、进行炉内石灰石脱硫等 ,可以降低N2 O的生成量。最后介绍了一些循环流化床燃烧过程控制N2

N 2O emission property under different operating parameter has been done in a diameter 20mm,450mm height fluidized bed combustion testing system.Experimental results have proved that N 2O emission can be reduced by lower exceed air ratio,higher circulating ratio,desulfuration with limestone and so on,and present some measures of controlling N 2O.
