日本大阪燃气公司与三菱重工业共同开发了中型的利用余热发电的燃气发动机 ,其发电效率达到世界最高水平 ,即 4 0 %。这种机型是在稀薄燃烧的燃气发动机上首次采用了密勒循环。比以往机型的发电效率提高了 5% ,热回收量提高 1 5% ,CO2 排放量减少约 1 3%。具有经济性和环保性两 Japan’s Osaka Gas Company and Mitsubishi Heavy Industries jointly developed a medium-sized gas engine that uses waste heat to generate electricity, generating 40% of the world’s electricity. This model is the first to adopt a Miller cycle on a lean-burn gas engine. Compared with the previous models, the power generation efficiency increased by 5%, heat recovery increased by 15%, CO2 emissions decreased by about 13%. Economical and environmentally friendly two
