New Delhi: GE Power India has been awarded a Rs 142-crore order from state-owned NTPC Limited, under which it will be responsible for supplying and installing a low NOx combustion system for 10 GW of thermal power plants at various locations in India. The order makes for the first big-ticket order awarded by the PSU on such a large scale for installing this technology at its thermal power plants, a statement released by GE Power said.
“The project involves in-combustion system modification of the boiler by staging the combustion air in the furnace to reduce the generation of fuel and thermal NOx during the combustion process. The combustion modification technology can help reduce 30-40 percent of NOx emissions from these coal-fired boilers up to a level of less than 400 mg/Nm3 at 6 percent oxygen content in flue gas on dry gas basis at Induced Draft Fan outlet,” the statement said.
The thermal power projects on the list
The projects where the new technology will be installed include the Mouda Super Thermal Power Station (STPS), Sipat STPS, Vindhyachal STPS, Simhadri STPS, Vallur Thermal Power Station (TPS) and Talcher STPS. GE Power is going to deliver the combustion system in a phased manner over a period of over 30 months, the statement said.
In 2018, GE Power won a contract from NTPC and Tata Chemicals to upgrade two coal-fired boilers owned by these companies with low NOx firing system — NTPC’s 2x490 thermal plant in Dadri, Uttar Pradesh and the 2x136 TPH Boiler Tata Chemicals Ltd in Mithapur, Gujarat. These orders were the first standalone order for low NOx firing system upgrade in any coal-fired power utility and industrial boilers in India, the statement said.
