Recently, the necessity of micro motive power has been arisen. The Ultra Micro Gas Turbine (UMGT) is expected as the new power sources. In this study, a premixed combustor of propane/air for 20W output UMGT has been proposed and tested. The combustor size is fixed of 42mm in outer diameter and 19mm in inner diameter, while the length L can be changed. The flame pattern, the lean flammability limit, and the temperature were measured under the atmospheric and high pressure condition, respectively. The combustion characteristics have been made clear by the results of the experiment under the atmosphere pressure. The stable combustion were realized under the 2.5atm pressure, and the highest temperature of combustor exit was of 1120℃.
