| Abstract | Toshiba has supplied and experienced long operations of several thousand kW to 110-120MW plants, thus we have now share of approx. 30% in total capacity of geothermal plants all over the world. The amount of total capacity of Toshibaís geothermal steam turbines has reached approx. 248MW with 7 units for Japanese domestic plants and more than 2556MW with 45 units for overseas plants. The recent Japanese domestic geothermal plants are represented by Uenotai plant(28.8MW) which is the first unit of a totally rationalized plant, Yanaizu-Nishiyama plant (65MW) applying parallel operation of gas extraction system by compressors and steam ejectors for high gas content, and Kakkonda No.2 plant (30MW) first applying a dry-wet cooling tower in Japan in order to prevent visual white exhaust moisture and icing of surrounding trees. |
