  • Process and apparatus for firing pellets
    Patent number: 4221559
    Abstract: A charge of pellets is moved on a traveling grate in succession through first and second drying zones, a preheating zone, first and second firing zones, and first and second cooling zones, in that order. The pellets are dried in the first and second drying zones, preheated in the preheating zone, fired in the first and second firing zones, and cooled in the first and second cooling zones. Cooling air is forced through the charge in the first and second cooling zones. A first stream of cooling air is exhausted from the first cooling zone and delivered at least in part to the first and second firing zones. A second stream of used cooling air is exhausted from the second cooling zone and delivered to one of the drying zones. A first exhaust gas stream is withdrawn from the second firing zone and cooled in a waste heat boiler.
