弯尾管helmholtz型无阀自激脉动燃烧器nox排放特性
, PP. 18-23
Keywords: helmholtz型脉动燃烧器,无阀自激式,弯尾管,过量空气系数,热负荷,nox排放特性
Abstract:
对弯尾管helmholtz型无阀自激脉动燃烧器的nox排放特性进行了实验研究。结果表明:当燃烧器结构不变时,尾管出口烟气中nox排放量在初始阶段随热负荷的增加而增大,当热负荷增加到某一值时nox的排放量最大,而后nox排放量随热负荷的增加而减少;nox排放量随过量空气系数的增加而减少;燃烧温度及烟气在高温区的停留时间对helmhotlz型脉动燃烧器nox排放量影响较大,一般存在一个较合理的热负荷区间,在此区间内虽然热负荷和燃烧温度较高,但由于烟气在高温区停留时间变短,nox排放量反而较低,这一特点对helmhotlz型脉动燃烧器运行时如何降低nox的排放量有指导意义。
