摘要

分析了流化床燃烧过程中N2O的生成与分解机理。为了验证N2O的生成与分解过程及其排放的主要影响因素

在小型热态流化床实验台上进行了油页岩燃烧N2O的排放特性试验

分别对过量空气系数、二次风率、循环倍率、床温等因素对N2O排放的影响规律进行了研究。试验结果表明:降低过量空气系数和二次风率以及提高循环倍率可以有效降低N2O的排放量;在床温为850℃左右时N2O排放量最高

当提高和降低床温时NO排放量均能得到有效控制。

Abstract

The mechanism of generation and decomposition concerning N2O emission from fluidized bed combustion of oil shale has been analysed.In order to verify the process of generation and decomposition of N2O emission

as well as the main factors affecting the N2O emission

a test study on N2O emission characters of oil shale combustion has been carried out on a small-sized hot-state fluidized bed combustion test stand

the regularity concerning influence of excess air ratio

secondary air rate

circulation coefficient and bed temperature etc.upon the N2O emission has been studied respectively.The results show that the decrease of excess air ratio and secondary air rate

as well as the increase of circulation coefficient all can effectively reduce the N2O emission.In the event of bed temperature being about 850 ℃

the N2O emission is maximum

increasing or decreasing the bed temperature all can effectively control the N2O emission.
