A turbo generator is the combination of a turbine directly connected to an electric generator for the generation of electric power. Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships.〔(The turbogenerator – A continuous engineering challenge )〕 Smaller turbo-generators with gas turbines are often used as auxiliary power units. For base loads diesel generators are usually preferred, since they offer better fuel efficiency, but on the other hand diesel generators have a lower power density and hence, require more space. The efficiency of larger gas turbine plants can be enhanced by using a combined cycle, where the hot exhaust gases are used to generate steam which drives another turbo generator. ==History== The first turbo-generators were water turbines which propelled electric generators. The first Hungarian water turbine was designed by the engineers of the Ganz Works in 1866; industrial-scale production with dynamo generators started in 1883.〔http://www.sze.hu/~mgergo/EnergiatudatosEpulettervezes/2013_1_feladat/ErosErika/V%EDzenergia%20hasznos%EDt%E1s%20szigetk%F6zi%20szemmel%20EL%D5AD%C1SANYAG.pdf〕 The turbo generator was invented by a Hungarian engineer Ottó Bláthy in 1903.〔(Bláthy, Ottó Titusz )〕 Unfortunately for Bláthy, Parsons had already demonstrated a DC steam-powered turbogenerator using a dynamo in 1887, and by 1901 had supplied the first large industrial AC turbogenerator of megawatt power to a plant in Eberfeld, Germany. Turbo generators were also used on steam locomotives as a power source for coach lighting and heating systems. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Turbo generator」の詳細全文を読む スポンサード リンク
