过量空气系数对DLN燃烧室性能影响的基本规律
摘要
进行了某重型燃气轮机(E级)燃烧室燃用天然气的试验
给出了在设计功率下过量空气系数在2.7~5.0时
燃烧室出口温度场、燃烧效率、污染物排放以及火焰筒壁温的变化趋势
以及过量空气系数对燃烧室性能影响的基本规律。随着过剩空气系数的增加
燃烧室出口温度场更均匀
NOx排放量下降
但过大的过量空气系数会导致燃烧效率下降。
Abstract
The performance test of a combuster for one heavy duty gas turbine(E-grade)
which burns natural gas
has been completed.The variation tendency of outlet temperature field in the combuster
the combustion efficiency
the emission of pollutants
and the temperature of flame tube wall has been discussed when excess air coefficient increases from 2.7 to 5.0 at the designed power
the basic influence regularity of excess air coefficient upon the performance of the dry-type low NOx(DLN) combuster being obtained.
