Getting fired up about primary NO measures in India28 October 2018
GE reports that its (formerly Alstom's) low NOx firing system has been selected for installation on NTPC’s 2 x 490 MW Dadri coal fired plant and on a 136 TPH Tata Chemicals coal fired boiler in Mithapur, Gujarat.
The low NOx firing systems, a “primary” emissions reduction measure, can reduce NOx by as much as 40%, and when coupled with secondary measures, such as SCR, reductions of 95% can be achieved, GE says, noting that India has over 170 GW of subcritical coal capacity and that coal is India’s energy mainstay and will remain so for a long time.
“This is the first order by any utility or industrial company in India for the firing system modification”, said Andrew DeLeone, MD of GE Power India Ltd, reducing NOx generation at source in combustion boilers. “The success of these projects will benchmark the technology and technical specifications for future low NOx firing system modifications in India.”
The projects are being implemented in response to India’s new coal plant emission regulations, which require all utility boilers as well as industrial and captive plant boilers to modify their firing systems to reduce NOx.
Earlier this year, GE announced successful completion of NTPC’s first wet flue gas desulphurisation (WFGD) unit, at Vindhyachal power plant and a contract to install a new WFGD at NTPC’s Telangana site.
