Westfalen AG in Munster has developed a new type of burner system for rotary drum furnaces. For the first time, the system combines a natural gas/hot air burner with a natural gas/oxygen burner, so that depending on the furnace charge and the progress of the process, the two burner types can be operated independently of one another or together. The aim of the development was to optimise economy and achieve in-situ after-burning of the total hydrocarbons within the rotary drum system.
