The burner in a rotary kiln functions as an injector the purpose of which is to draw the secondary air coming from the cooler into the flame in order to make the fuel burn as close as possible to the centre line of the kiln This explains why the momentum of the burner is the parameter that determines flame formation A higher• reduction of kiln inlet gas temperature thanks to improved combustion efficiency • reduction of kiln/riser duct plugging thanks to lower sulphur volatilisation in kiln • improved clinker quality Well adapted to the new challenges of modern rotary kiln firing using low grade fuels a ROTAFLAM burner retrofit to the latest VERSION
