Abstract
Micro gas turbine systems have been developed for a portable power supply. In this study kerosene spray with pre-vaporized system for the micro gas turbine combustor was tested. Fundamental characteristics of the kerosene spray with fuel vaporization on a hot wall were investigated experimentally. A model combustor of micro gas turbine was used for combustion test of kerosene spray. In the combustion test, an extension tubes were set at the exits of fuel injectors for the enhancement of pre-vaporization of kerosene spray. The effect of the extension tube on flame stability was discussed. As a result, the blow off limit became wider when the extension tube was set at fuel nozzle exit.
