초록
Experimental study has been carried out to understand combustion characteristics of a swirl-stabilized premixedgas turbine combustor for power generation. NOx and CO emissions, extinction limit, pressure loss, andtemperature distribution were measured for various operating conditions. Results show that, with increasinginlet air temperature, NOx is increased due to a higher adiabatic flame temperature while CO is increased ordecreased for low or high A/F ratio regime, respectively. depending on the flame location. With decreasingload from the design condition, NOx is decreased as thermal load is reduced. With further decreasing load,however, NOx is increased due to a longer residence time. CO is decreased and then increased with decreasingload. Flame extinction limit is extended with increasing inlet air temperature as the recirculation strength isenhanced.
