Abstract
Micro gas turbine systems have been developed as a portable power supply. In this study the utilization of kerosene spray with pre-vaporized system for the micro gas turbine combustor was tested. Characteristics of the model combustor of micro gas turbine were investigated experimentally. Twin fluid atomizer was used for the fuel spray formation. An extension tube was set at the exit of fuel injector for the enhancement of pre-vaporization. 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.
