GE achieves WFGD firsts in India and South Africa18 July 2018
GE has reported successful trial operation of a turnkey full flow wet flue gas desulphurisation (WFGD) project at NTPC’s 500 MW Vindhyachal pulverised- coal-fired plant in Madhya Pradesh. The FGD installation at Vindhyachal is described as “the first limestone-based WFGD commissioned in an NTPC power plant suitable for continuous operation at a 500 MW unit for 100% gas flow.”
GE’s scope, as well as delivery of the WFGD system, included design, engineering, manufacturing, testing, civil works, erection and commissioning. GE describes the project as a key step towards implementing SOx control systems mandated by India’s Ministry of Environment Forest and Climate Change (MoEFCC) for coal fired power plants.
Andrew DeLeone, managing director, GE Power India, said completion of the trial operation put “GE Power in a unique position in the country as India gears-up to implement deSOx solutions in an installed base in excess of 150 GW.”
GE’s other FGD installations in India include seawater based systems at Tata Power, JSW Ratnagiri and Adani Mundra.
Meanwhile, in South Africa, GE has successfully completed performance testing of the wet FGD system installed on unit 1 of Eskom’s 6 x 800 MW Kusile power plant, currently under construction. It is South Africa’s first FGD system.
During the tests, the WFGD system achieved a “93% removal efficiency rate”’ says GE, and “exceeded original performance commitments.”
GE took on the Kusile project with its purchase of the Alstom power businesses in 2015. As well as the WFGD technology, its scope includes EPC of six turbine islands and air cooled condensers.
