Over the last decades, many countries have periodically tightened the NOx emission regulation for thermal power plants, and the trend towards lower emission limits continues. With 30 years of global experience in designing and implementing low-NOx combustion refurbishments with various fuels, Fortum is in a unique position to offer advanced low-NOx combustion know-how and technology. We have the expertise to meet the desired emission levels, regardless of the current set-up at your site. An optimal combustion solution is designed to fit any original equipment manufacturer's (OEM) technology with minimum capital expenditure.

Fortum eNext has been a forerunner and developed its own low-NOx solution based on primary methods. Implementing this technology and using low-NOx burners or modified burners in conjunction with carefully designed overfire air (OFA) nozzles, the NOx emissions in power production can be reduced to a level below 300 mg/ Nm3. Employing primary methods has no impact on operational expenses nor boiler behavior, therefore always being a wise choice of technology. In case further reduction is needed to reach even lower emission level, additional secondary methods can be applied, still keeping the total investment as cost-efficient as possible over time.

Why employing primary methods for NOx emission reduction is cost-effective?

Fortum eNext low-NOx delivery steps

Fortum's low-NOx delivery always starts with an assessment of the current design and performance of the boiler, and by analysing data provided by the customer. As a second step a computational fluid dynamics (CFD) modelling is conducted to design an optimal OFA system and required burner modifications for the case in question, to achieve the required NOx emission reduction.  Technical implementation will be carried out as an efficient turnkey project in co-operation with our local partners with short production downtime.

"Implementing primary NOx reduction methods entail lower operating and maintenance costs as compared to secondary methods, thereby ensuring that overall life-cycle costs are kept at minimum. Moreover, primary methods not only reduce emissions, but also enhance plant performance through optimisation of boiler operations."
