Industrial applications of Tenova FlexyTech
flameless
low NOx burners
M. Fantuzzi and L. Ballarino (Published online: 1 May 2008)
Abstract
Environmental emissions constraints have led manufacturers
to improve their low NOx recuperative burners. The development
by Tenova of the FlexyTech Flameless burners with
low NOx emissions, even below the present "Best Available
Technology" limit of 40 ppm at 3%O2 with furnace temperature
1250°C, air preheat 450°C, is described. The results achieved
during the R&D programme have been also improved in
the industrial installations. Some details and performances of
the recent furnaces equipped with such burners are provided.
