Outline of Final Research Achievements

The development of a micro gas turbine of a power of 5 kW which is able to use low caloric biogas fuel and the investigation of the combustion characteristics have been implemented. The biogas fuel originated from sewage has been examined as steady and prospective fuel. However, the fuel contains a lot of nitrogen and the carorific value is one tenth of methane. Thus, both low NOx and steady safety combustion technologies are required simultaniously. Then, a cyclon jet combustor developed in our labolatry has been applied to the micro gas turbine . For a carorific value of 3400 kJ/Nm3, steady and low NOx combustion has been accomplished under a fuel ratio of 1:3:1 for a jet and a swirler on the first stage and a swirler on the second stage.
