To realize hydrogen-fueled micro gas turbines with high efficiency and low NOx emission for distributed electrical power generators, we have proposed a rich-lean hydrogen-combustor with a clustered coaxial injector. A test combustor with three coaxial injectors arranged in a straight line was built to examine the effects of interferences between two jet flames or a jet flame and a combustor side-wall. An appropriate distance between the injectors was effective to shorten the flame length and to prevent the flame reattaching to the side-wall. Clustering the coaxial jet flames seldom affected the emission characteristics. High combustion efficiency almost 100[%] and low NOx emission below 3[ppm16%O_2] were attained in the test combustor at total equivalence ratio condition of 0.5.
