Duvha Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom. The tall chimneys at Duvha are the second and third tallest structures in Africa, only a chimney located at the Secunda CTL plant is taller. ==History== Construction of Duvha Power Station started in November 1975 and the last unit came into operation in 1984. In 1993 Duvha became the first power station in the world to be retrofitted with pulse jet fabric filter plants on three of its six units. These plants contribute largely to the reduction of air pollution by removing 99.99% of the fly ash, which otherwise would be released into the air through the station's chimneys. On 8 January 2003, Unit 2 generator exploded while being returned to service after a malfunction.〔http://www.massengineers.com/generator_accident_in_africa.htm Generator Accident in Africa〕 On 9 February 2011 another unit failed catastrophically while performing over speed testing.〔http://www.eskom.co.za/live/content.php?Item_ID=17647 Media Statement〕〔http://www.news24.com/SouthAfrica/Politics/Eskom-makes-R3bn-boo-boo-20110327 Eskom makes R3bn boo-boo〕 The units are over speed rated at 3600rpm and the last recorded speed before failure was 4250rpm. The first power station in South Africa to have a black power station manager, Ehud Matya. 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「Duvha Power Station」の詳細全文を読む スポンサード リンク
