Fortum eNext, a part of Finnish clean energy firm Fortum, has completed its first commercial combustion modification project in India at Hindalco-Mahan Aluminium, in Madhya Pradesh. The project was aimed at reducing nitrogen oxides (NOx) emissions on one of the 150-MW boilers located in the state of Madhya Pradesh, a Fortum statement said.
According to statement the NOx emissions of a coal-fired boiler are for the first time cut down to such an extent that NOx levels reached well below 300 mg/Nm3 in all loads and mill combinations.
The project started in June 2019, and the boiler was commissioned in March 2020, and has been in operation since then but due to COVID-19 the comprehensive Performance Guarantee Tests were completed in October 2020.
Fortum has advanced technology for bringing about NOx reduction up to the statutory limits by using only primary combustion modification on the boiler with minimal capital expenses and no operating expenses, the statement said.
