Recently, the necessity of micro motive power has risen. Then, the Ultra Micro Gas Turbine (UMGT) is expected as the new power sources. Premixed-flame combustor of n-butane/air for 20W output UMGT was tested. The combustor size is 42mm in outer diameter and 19mm in inner diameter and the length L can be changed as follows ; 3.7mm, 6.7mm, 8.7mm. The influence on the flame shape, the limit of stability of combustion, the temperature distribution in the combustion chamber, and the gas temperature at the exit combustion when the length of combustion chamber and the equivalence ratio were examined. Although stable flame was not formed for L=3.7mm, stable flame can be formed for L=6.7mm, 8.7mm. The highest gas temperature at the exit combustor was 1080℃.
