The combustion characteristics have been investigated to develop the
low NOx gas turbine combustor. The lean premixed combustion
technology was applied to reduce NOx emission. And also, to improve
flame stability adopted dual-swirl combustor. However, combustion
instability is a serious obstacle for the lean-premixed combustion
of gas turbine and can even cause fatal damage to the combustor
and entire system. Thus improved understanding of mechanisms of
combustion instability is necessary for the design and operation of gas
turbine combustor. In the present study, in order to understand the
instability phenomena and the stability characteristics of a premixed,
swirl-stabilized flame were studied at moderate pressure and
ambient temperature condition. Also, to determine the effects of
hydrogen addition on flame stability under fuel-lean condition.
Then, in this research, several combustion tests using a simulated
synthetic natural gas(SNG) fuel with varying fuel composition.
These results provide the combustion instability mechanism and
effect of hydrogen in lean-premixed dual swirl combustor. It is can
help to design the more improve gas turbine combustor.
