New burner technoloqy: Turning low-grade scrap metal into high-efficiency savings

摘要

Faced with today's tough economic conditions, aluminium plants across Europe are looking for better ways to process low-grade scrap metal. It makes good financial sense, but it also presents many challenges. Low-grade scrap metal is often contaminated with oil, paint and plastic and this is where the problems emerge. Heavy fumes, flames and post-combustion outside of the furnace cause high temperatures in the ducting system and influence baghouse operation, efficiency and emissions.
