Patent
·
OSTI ID:5610749
The present invention relates to a method for efficiently incinerating waste material, particularly dewatered sludge, in a multiple hearth furnace by controlling the temperature of the individual hearths of the furnace within certain prescribed limits by modulating the amount of combustion air, and controlling the temperature of the afterburner or combustion hearths to within certain prescribed limits by splitting the feed sludge between the first two upper waste material handling hearths.
