UP Rajya Vidyut Utpadan Nigam (UPRVUNL) is constructing two large new power stations using Super Critical boiler technology. One is the Obra “C”, 2 x 660 MW project, and the other is the Jawaharpur, 2 x 660 MW project. The Jawaharpur project is owned by Jawaharpur Vidyut Utpadan Nigam Limited (JVUNL) which is a 100% subsidiary company of UPRVUNL. Both projects are designed and constructed by Korean company Doosan and both will use efficient “Flue Gas Desulphurisation (FGD) Plants” as mandated by Ministry of Environment, Forest, And Climate Change (MoEFCC).
As a result of using FGD plants, the flue gas in the chimneys will have a low temperature and it will be highly corrosive. In order to ensure that the chimneys would be durable and reliable, UPRVUNL had specified the use of high quality, well-proven chimney lining system from the United States, which has been used by power stations worldwide.
