燃气轮机污染物排放影响因素相关性分析
摘要
为研究某重型燃气轮机污染物的排放特性
本文监测并获得了某电厂热态启机过程燃气轮机排烟通道内污染物排放数据
分析了NO_x等污染物排放规律
并采用统计学相关性分析方法
研究了燃气轮机负荷、值班燃料流量、空气流量等因素与污染物排放之间的相关性。结果表明:热态启机过程中
值班燃料流量、空气流量与NO_x排放之间呈正相关
NO_x排放随值班燃料流量增加而升高;燃气轮机燃烧调整时
可通过减小值班燃料流量控制阀和燃烧室旁路阀开度来降低NO_x排放。
Abstract
To study the emission characteristics of a heavy-duty gas turbine
the pollutants emission data from flue duct of a gas turbine were monitored and obtained during hot startup process
the emission characteristics of NO_x and other pollutants were analyzed
and statistical correlation analysis methods were used to study the influence of gas turbine load
pilot fuel flow and air flow on the pollutant emission of gas turbine. The results show that
there is a positive correlation between the pilot fuel flow
air flow and NO_x emissions during the hot startup
and the NO_x emissions increase with the pilot fuel flow. During combustion adjustment
the NO_x emissions can be reduced by cutting down the opening of the pilot fuel flow control valve and combustion chamber bypass valve.
