Micro gas turbine system is now received much attention for a local energy plant. As for the viewpoint of fuel, an energy plant using liquid fuel is desirable because of safety and smooth fuel supply even id the emergency situation such as earthquake. Also combustion emission from energy plant should be minimized for daily use of the plant. Ultra low Nox combustor with liquid kerosene fuel is developed as a micro gas turbine combustor for this purpose. The developed combustor has a unique flow system that is called upward swirl flow. This flow can form the upward reverse flow with burned gas re-circulation and is effective for flame stabilization with high turbulence. Also it is effective to attain a low Nox combustion by the effect of BGR. The main results obtained here are as follows. (1) Longer length of primary combustion zone results the undesirable combustion such as CO and Nox increases and low stability of flame. (2) The effect of vane angle of the swirl generator is not so much, however HC and CO emissions increase when the swirl generator is eliminated. (3) Air guide vane set at the bottom end of primary combustion zone shows the strong effect on the flame stabilization. For flame stabilization, enough height of vane is needed. Also an enough size of throat diameter at the outlet of primary combustion zone is needed for flame stabilization. (4) An optimization among the size of primary combustion zone, swirl generator, air guide vane and outlet throat results the enough emission performance of the combustor. Nox emission index less than 0.8 g/ (kg-fuel) and CO emission index less than 10 g/ (kg-fuel) can be attained under the primary excess air ratio of 1.5 〜 1.6

微型燃气涡轮机系统正在获得当地的燃料，因此燃料供应量为Earther，例如Earther。具有称为向上旋流的独特流动系统得到的BEURE是（1）更长的引发区的长度会导致不适应的旋转和低稳定性，而旋转的稳定性并不多。 3）在初级燃烧区的底部设置的空气导灯对火焰稳定性的强烈影响，还需要足够的GHT叶片。在燃烧器的旋转发电机TS中，燃烧器的发射性能少于10 g/（kg燃料）。
