| 内容記述 | We have proposed two types of hydrogen-fueled micro combustors: one is for an Ultra Micro Gas Turbine (UMGT) generating a 16-W output and the other is for a Micro Gas Turbine (MGT) generating a 3-kW output. For the ultra-micro combustor of the UMGT, we clarified the most important issues, such as quenching distance, heat losses, shortened diffusion characteristic time and flow laminarization. This clarification led to a unique burning method, which is called the flat-flame burning method. A prototype of a flat-flame ultra-micro combustor with a volume of 0.067 cm3 was made and tested. It was found that the flame stability region of the flat-flame, which is governed by the heat losses in the combustor, satisfied the optimum operation region of the UMGT. The combustion efficiency achieved was more than 99.2 %. The excellence of the flat-flame burning method in the ultra-micro combustor for the UMGT was confirmed. For the MGT with a 3-kW output, an annular-type hydrogen-fueled combustor with an air flow rate of 50 g/s was designed, and a sector-model test combustor of the annular combustor was made to determine its combustion characteristics. By using swirlers with a strong swirl intensity and four-hole fuel injectors, outstanding performance was attained for flame stability, space heating rate, temperature distribution and combustion efficiency. |
