Metso Outotec launches Ferroflame[TM] LowNOx burner for travelling grate pelletizing plants

Metso Outotec Corporation’s press release on March 24, 2022, at 09:00 a.m. EET

Metso Outotec is launching the innovative FerroflameTM LowNOx burner for travelling grate pelletizing plants to enable pellet plant operators to achieve the stringent NOx emission targets with ease. The new burner is part of the company’s Planet Positive offering focused on environmentally efficient technologies.

The FerroflameTM LowNOx burner uses high-speed dilution, which is an effective way to improve the combustion process and reduce NOx emissions. It works seamlessly with natural gas, and tests demonstrate that can also be used with diesel and coke oven gas. 

“We are very excited about the FerroflameTM LowNOx burner, our emission- and cost-efficient alternative to minimize NOx emissions from the combustion process. Its functionality and performance with natural gas have been proven on-site. The burners have been operating successfully at a client site since 2019,” shares Dr. Andreas Munko, Senior Product Manager, Ferrous and Heat Transfer at Metso Outotec.

Metso Outotec’s FerroflameTM LowNOx burner provides the following benefits:

  • Up to 80% reduction of NOx emissions
  • Expected thermal penalty on natural gas ~10%
  • Increased pellet homogeneity and quality
  • Increased refractory lifetime
  • Optimization of NOx vs. Opex with digital solutions possible
  • Proven technology
  • Easy retrofit of existing plants

More information about LowNOx burners is available on our website.

Metso Outotec will host a free webinar where the LowNOx solution will be discussed in more detail on March 30, 2022, at 10:00 a.m. and 15:30 p.m. CET. More information on the webinar including registration details can be found here.
