Outline of Final Research Achievements

This research aims to develop the lean premixed, prevaporized combustion of liquid fuel by using the porous material injector toward the realization of combustor for several hundred W-class micro gas turbines. The kerosene fuel was successfully vaporized in the cylindrical ceramics porous injector. The results of flame appearance, flame stability limit, and exhaust gas emission indicated the occurrence of the lean premixed combustion. The combustor attained the NOx emission of less than 15 ppm under the combustion efficiency of more than 99.7% and the pressure loss ratio of less than 2%.
