日本通产省研究所推出最高热效率为29.2％的小型节能燃气轮机。这种燃气轮机的燃烧室、气道和其它主要零件都采用了耐热陶瓷。普通金属燃气轮机的最高热效率只有20％。陶瓷燃气轮机样机在39小时试运行过程中,发出的功率为300千瓦。
The Japan Institute of International Trade and Industry launched the small energy-saving gas turbine with the highest thermal efficiency of 29.2%. This gas turbine’s combustion chambers, air passages and other major parts are made of heat-resistant ceramics. The highest thermal efficiency of ordinary metal gas turbines is only 20%. The ceramic gas turbine prototype emits a power of 300 kilowatts during the 39-hour test run.
