Enhanced Control by Visualisation of Process Characteristics : Video Monitoring of Coal Powder Injection in a Blast Furnace
This master thesis, based on work performed at Luleå University of Technology in cooperation with Mefos, is about measurement of pulverised coal flow injected into a blast furnace, compensating for some of the usually used coke. Coal is drawn from an injection vessel and transported under pressure w...
