摘要
利用构建的燃烧室化学网络模型,对燃气轮机燃烧过程中污染物排放受当量比、压力及火焰区滞留时间的影响进行了分析。结果表明:当量比增加,燃烧室出口CO及NO的摩尔分数增加;压力增加,燃烧室出口CO及NO的摩尔分数减小;火焰区滞留时间增加,燃烧室出口CO摩尔分数减小,NO摩尔分数增加;在贫燃预混燃烧条件下,当量比对燃烧室污染物排放的影响最大。
The effects of equivalent ratio, pressure and residence time on pollutant discharge of gas turbine during combustion process were investigated by using a self-constructed chemical network model. The results show that,at the combustor outlet, the CO and NO mole fractions increased with the equivalent ratio while decreased with the increasing pressure. The CO mole fraction decreased while the NO mole fraction increased with an increase in residence time. The equivalent ratio had the most obvious influence on pollutants discharge under lean premixed combustion condition.
