Resumo

Energy efficiency, equipment reliability and cost reduction are of the key factors in any efficient plant. Badische Stahlwerke (BSW) started using its own burner technology in 2001, this was developed by Badische Stahl-Engineering (BSE). Over the past 15 years, Badische improved all aspects of its Virtual Lance Burner (VLB), to perfectly fit all steelmaking requirements. This tiltable VLB was first tested at BSW’s electric arc furnace no. 2 in 2012. Promising results like reduction of refractory wear, energy efficiency, reliability, etc., were obtained. At the same time the existing VLB system was further improved with regards to the design of the water-cooled copper box. Today in 2016 both EAFs at BSW are equipped with the new patented tiltable system and the new copper box design. The paper will describe the results of the past years at Badische, but will also show the performance at other installations.
