Secondment at Bekaert Company

• Furigas started in 1972 as manufacturer of atmospheric burners.
• Premixed technology + condensing boilers started in the 1980’s
• Driven by low NOx and higher efficiency demands
• NIT was bought from Bekaert
• 2000 acquisition : Bekaert Combustion Technology
• Premixed technology is sensitive to thermo-acoustics instabilities
• Since 2005 BTC has been developing a dedicated team in order to

predict and prevent thermo-acoustic noise
