  • Process and equipment for firing pellets
    Patent number: 4332551
    Abstract: Pellets to be fired are treated with high-temperature gases which, before being supplied to the pellets, are heated by combustion of fuel in a combustion chamber to a temperature above the temperature at which the pellets are to be treated and high enough to ensure that slag formed during combustion can be tapped in liquid form. Cooler gases are then admixed to the high-temperature gases outside the combustion chamber and before they are supplied to the pellets to cool the gases to the temperature desired for the treatment.
