碩士 === 國立交通大學 === 機械工程系所 === 96 === Based on the low-heating-value fuel obtained from the bio-process from marsh gas by removing H2S, it develops a micro gas turbine (MGT) with turbine wheel diameter 40mm by modifying the system from a liquid-fuel burning gas turbine system into a gas burning one to generate the combustion power, which is used to drive a generator to produce the electricity. It is a co-generation process, which can be one of the potential candidates for the distributed power supply systems. In the experiment, the pressure and the volume flow rate of fuel, rotational speed of turbine and the temperatures of important parts of MGT have acquired. According to the data, the better generator can be chosen, and the output by using 90% CH4 with 10% CO2 reaches about 170W at 85,000 rpm. When low-heating-value fuel of 60% CH4 was applied, the power output was extremely low. Also, this research would be compared to gasoline to ensure its practical utilization. Finally, the MGT system also intends to evaluate the possibilities of the system integration with other renewable energy resources, such as the wind and solar powers.
