A gas turbine operated to generate few 3kW electric power output is now developed under the fund of NEDO. The combustor for the gas turbine is very small compared to the conventional gas turbines for industrial or aero-engine use and various problems are coming out. One of the problems is lack of residence time to complete the chemical reaction and the other one si the increasing heat loss from the liner. An annular type combustor fueled by propane with 90mm of outer diameter and 40mm of inner diameter is now developed. The main fuel is premixed with air and supplied through narrow slits generating swirling flow. The premixed flame is stabilized by a lot of diffusion flame held at the inner side wall. At present the combustion stability is measured for various conditions, and the exhaust emission is also measure to evaluate the completeness of chemical reaction at the exit. For the convenience of the authors, an example of the manuscript for the Gas Turbine Conference of the Gas Turbine Society of Japan is shown.
