R&D Trends

Radiant tube and direct-fired burners are both used for heat treating furnaces. Radiant tube burners have historically been used in batch annealing furnaces. Direct fired burner technology is being applied more due to advancements in firing techniques that produce better air/fuel ratio and temperature control, improved gas circulation techniques and new materials for metal inner covers. Direct-fired reducing burners are being developed for continuous heat treating lines as discussed in the R&D section.
