    초록 The combustion characteristics have been investigated to develop the low NOx gas turbine combustor. The leam premixed combustion technology was applied to reduce the NOx emission. Also, the conventional combustor was designed and tested for the baseline of low NOx combustor
    performance. The test was conducted at the condition of high temperature and ambient pressure. The combustion air which has the temperature of 500K were supplied to the combustor through the air preheater. The temperature and emissions of NOx and CO were measured at the exit of combustor. The premixing chamber can be operated very lean condition of equivalence ratio around 0.35. The NOx was decreased with decreasing the equivalence ration. The CO was decreased with decreasing the equivalence ratio, but the CO was increased with decreasing the equivalence ratio helow 0.45. But, at the very lean condition of equivalence ratio below 0.45 hotb NOx and CO were
    increased because of the flame unstability. The NOx was decreased slightly and CO was increased with increasing inlet air flow'ate. This results c;m be used to determine the size of combustor. The low NOx combustor has lower values of NOx and CO compared with conventional one. Consequently the performance of combustor shows the possibility of the application to the gas turbine system.
