GE Power India Ltd. (GEPIL)* has been awarded a Rs 142 crore (USD 20 million) order by NTPC for supply and installation of low NOx combustion system for 10 GW of thermal power plant capacity across the country. This is the first project awarded on such a large scale by NTPC to install low NOx combustion technology at its thermal power plant fleet.
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% of NOx emissions from these coal-fired boilers up to a level of less than 400 mg/Nm3 at 6% oxygen (O2) content in flue gas on dry gas basis at Induced Draft (ID) Fan outlet.
The projects that have been selected for installation of low NOx combustion systems includes Stage-I (2X500 MW), Mouda Super Thermal Power Station(STPS); Stage-I (3X660 MW) & Stage-II (2X500 MW) Sipat STPS; Stage-III (2X500 MW); Stage-IV (2X500 MW) & Stage-V (1X500 MW), Vindhyachal STPS; Stage-II (2X500 MW) Simhadri STPS; (3X500 MW) Vallur TPS; Stage-III (2X500 MW), Talcher STPS. The low NOx combustion system will be delivered in a phased manner over a period of over 30 months.
"We are truly delighted to have received this prestigious order from NTPC which is reflective of the commitment of GE towards helping the country address the critical issue of emission from the coal power plants. With more than 150 GW of coal-fired plants operating at sub-critical level, India is the world's second largest NOx emitter, contributing close to 30% of annual NOx emissions of the country's industrial sector", said Lalit Sankrani, Clean Combustion Leader - GE South Asia.
"While the industry is slowly waking up to adopt new technologies such as Flue Gas Desulphurisation (FGD) for curbing SOx emissions from thermal power plants, there is still a journey to be covered as far as addressing NOx emissions are concerned. It is high time de-Nox solutions are also taken seriously to address the emissions compliance needs for the country," he further added.
